Vintage Derale Oil Cooler

Work is finally completed for the season. Will be heading South this coming week. Looks like we'll have good weather for the trip for a change. Typically we are racing snow storms heading South.
Have a large list of repairs to do this Winter.
Finally found a vintage aftermarket "Derale" oil cooler which hopefully will fit the sidecar rig.
Cooler was listed for $80.00 + shipping on takers and it continually dropped in price until it was offered for $30.00 Total, shipping included. Couldn't pass that deal up.
UPDATE: After some research I found  some facts concerning this particular cooler set up. The design led to some failed engines and were known "in the day" to be a piece of crap. Tom Cutter stated that many people who installed this cooler soon became "pedestrians"$30.00 "down the drain" I guess. Won't be installing it. 
I'm glad I reached out for others experiences prior to using this.

 Been running the side hack with only the "Brielle" oil pan cooler. It's cooling effectiveness is marginal at best. Plus it has developed leaks around the gaskets. I'll renew both gaskets this winter while I have the bike pulled apart.

Still "on the fence" as to whether I'll install the newly rebuilt 5 speed or the newly rebuilt 4 speed on the sidecar. The 4 speed is a bit more robust, but I do like the 5 speed for the extra gear range. Bob C. at "Bob's Motorwerks" rebuilt both transmissions and found serious issues with the 4 speed. It now has all new bushings, bearings and springs, plus other parts. It had evidence of getting pretty hot at some point due to a poorly adjusted shift fork. Bob was confident of it's rebuilt condition though.
I'll have the rig torn "down to the bones" for a week or more. Hoping to do some long range rides next season so will address any issues / upgrades I can think of. 
Due for a couple of tires on the side car and the Gold Wife hates the word "tire" it always seems to be a topic with

The old Gold Wing has developed an issue....either starter or solenoid. I know the 8+ year old battery is shot so will replace that first. 

The Slash 5 will get a "newer" pair of later model carbs which I obtained. I will need to tear them down for a rebuild likely, although they appear to be ready to go. I'll go through them of them has a different float bowl on it with dual independent floats.

BMW Transmission rebuilds update / Beartooth & Yellowstone Park

Appears that Bob @ "Bobs Motorwerkes" has completed the 1974 five speed rebuild. He found that the transmission was a VERY early manufactured unit. Shimming limits were found due to the case design....available shims either left the gear train sloppy...or too tight. Bob called and had a simple solution....double gasket on the rear cover. This will allow the use of available shims and leave enough end play. He said in all the hundreds of transmissions he has rebuilt, he had never ran into this situation. He did not like the "double gasket" solution but short of changing the rear cover, it was the only option he could come up with. I told him to continue with that scenario. Over all the transmission was in very good condition. He changed all springs, and all the bearings showed no wear / issues, so they will be reused. 
The 4 speed, which I thought would be an easy rebuild was another matter.... all the bushings were worn out, bearings not much better. Also someone had forced a reassembly in the past and "galled" a shaft....also, the rear output seal was installed backwards. So, the cost of this rebuild will be higher than I hoped. All new bushings, bearings and springs, plus machine work on the galled shaft. But the bottom line is that it will be a reliable unit for the sidecar, and I'm looking forward to tearing down the sidecar this Winter for a refit.
On the slate: Oil pan leak needs to be addressed.....push rod tube/ seal replacement  (seal retainers are loose on tubes, causing leaks) .....change out rear swing arm to a "cush" unit I have....change out transmission......maybe even touch up some of the sidecar frame

Didn't get many miles on the BMW's this Summer. My old /5 is suffering from Carb. issues so I bought a pair of newer model (1973/ 74) carbs to rehab this Winter. The early Code /3 /4 Bing Carbs had inherent design issues.

Did have a nice day ride through Yellowstone Park via the Beartooth Highway on the old Gold wing. It performed flawlessly as usual. Took advantage of the 320 mile fuel range.

Time for a Sidecar Re-Fit

I'm seriously considering retiring from the working world this Fall so with that in mind will be planning some serious sidecar trips with my Wife. Our last "long" trip (in the only 800 - 1000 mile range) was to Death Valley in 2016. That trip brought forth possible transmission issues when a serious noise developed when I ran the bike hard, overheating the transmission. I change gear lube quite often and am finding metal "flakes" starting to show up on the magnet. So, the transmissions' service life is coming to an end. Rather than remove / rebuild that transmission I decided to have a couple of spare tranny's I had rebuilt for the swap. Both the transmissions came from "derelict" bikes so I have no clue of their condition. Both bikes (I was told) were in running condition before my acquisition. One with the 4 speed was a crash victim, the 5 speed bike had an engine issue. No way was I going to install either of them without inspection / rebuilding. Only want to install once!

Near "As New" input splines:

I had this clean 1972 R75/5 Transmission stored away and have decided to install it behind the R100S sidecar engine. Bob Clement, owner of Bob's Motorwerks, is in the process of rebuilding it and also a spare 1974 Five Speed I had sitting. The 74 five speed transmission has the kick start. That is the same model transmission I'm using in the sidecar now. The 4 speed is a more "robust" design and Bob recommends it for the sidecar.

                                           Bob Clement with his Gold Wing sidecar

I'm currently running a 32/10 final drive with the 5 speed, but that might be a bit high geared for the 4 speed. I also have a 37/11 final drive which is one range lower geared so can swap if wanted.

I've noticed that my rear wheel appears to have a bit of a left "lean" so think the swing arm is probably "tweaked" a bit. Tire wear is normal, handling is not affected so I haven't bothered to do anything about it. Since I'm changing out the transmission, I'll swap out the swing arm with a heavier, later model LWB one I have.

Lastly, I may pick up a pair of matched replacement pistons / cylinders (currently on EBay) to have on hand if needed. The cylinder heads were redone, with new valves / seats / guides a few years ago so should be good for a while yet. I do have a loose pushrod tube on a left cylinder, although it is not leaking, the pushrod tube seal collar is loose and doesn't properly compress the seal to the engine block. I put a couple of hose clamps on the tube collar a couple years ago as a stop gap fix.

So this Winter I will separate the sidecar and go over (at least) the following....Transmission change, inspect clutch (only a couple years old / maybe 10,000 miles on it), change out swing arm, check and /or replace swing arm bearings, possibly swap out Final Drive, reseal oil pan & cooler which have been leaking, replace pushrod tube seals, new tires, and  go over all ignition system components.

As the bike sits now, I would not take off on a multi thousand mile trip as I know the Transmission is tired. Although it still works fine and shifts well, I know its' days are numbered.

Bob works quickly so should have transmissions back in a week or two. His fees are reasonable:
$350.00 Labor + parts for the 5 speed and  $450.00 Labor + parts for the 4 speed. So, barring any major parts needs, I should have both redone for under $1200.00, which I think is reasonable.

Big Horn River / Yellowstone River / Musselshell River Loops

Took a ride this weekend and last weekend. Last weeks ride took me over to the Crow Indian Reservation, near where I grew up. Pretty warm day and I made a pretty "mad dash" for a couple hundred miles. Stopped at an old fishing access site we used to frequent when I was a kid.

River was running pretty high. I stopped for a few minutes....found a nice little pocket knife laying on the rivers edge. This is the "Two Leggins" Fishing Access.

Today I decided to take a bit further of a ride. Filled the auxiliary fuel tanks to the brim and wanted to recheck maximum mileage with all the tanks full. Decided to go North to Roundup Montana, then East to Forsyth Montana. From there I followed the Yellowstone River to Sarpy Creek Road, which leads back to my hometown, Hardin Montana. Also there is a little Bar / Grill, the Spring Creek Bar, along the route. They have great burgers and fries so that was my motive for the route.

I've had issues getting the two auxiliary tanks to draw fuel evenly. I installed vent caps on the vent lines. The problem with the vents installed is that they will draw air into the tanks, but do not allow air to escape. This prevents the tanks levels from equalizing. I've found that by occasionally reaching down and cracking the filler caps loose that the tanks will equalize. The caps are o-ring sealed and take about 6 - 7 turns to remove so chances of one falling off is nil. I will likely just remove the one-way vent caps on the vent lines, which are routed under the seat to the rear.
The bike quit at 135 miles thru the auxiliary tanks, so with 5 gallons more in the main tank, I should have a minimum of 350 mile range. I was running along at a leisurely pace of 60 - 65 MPH. Typically get about 42 - 45 MPG at that speed.
I would bet that there is still fuel retained in the auxiliary tanks as they each took 1.8 gallons when I installed them. I think the only way to get every drop out, would be to plumb them separately with two petcocks, one for each auxiliary tank. That would be a plethora of fuel lines so don't think I'll do that....

Yellowstone full....lots of trees / debris floating down the river.

 Yesterday, 2 gals attempted Kayaking the river, both capsized and had to be rescued near Billings. Anyone on the river at this stage either has a death wish, or is just plain stupid....

Arizona - Boondocks near Hyder AZ, Gila River / Agua Caliente

Yesterday was a bit cool and windy, but a perfect day for a quick tour in the AZ, "boonies"...I wanted to test range again with the auxiliary fuel tanks I installed. I made sure all tanks were completely full. The auxiliary tanks run off one petcock. The bike stumbled at a mere 72 miles so I switched to the main tank. I made a stop at Dateland AZ and opened up the caps on both side tanks...finding fuel still visible in one of them above the "metal foil" in the tanks.....after sitting for a minute with the caps off, I could see the fuel level change, equalizing itself in the tanks. I got back on the freeway and ran another 35 miles before "drawing air" again. So I now know I can run a minimum of 100 additional miles with the side tanks, using approx. 2.5 gallons (at 40 mpg) of the tanks quantity. I might now drain the remaining fuel just to see how much is retained in the tanks. If my original "fill" quantities are correct, only a 1/4 to 1/2 a gallon would remain in the combined tanks.

Running 2 individual petcocks / isolating each tank might take care of the non-balancing fuel issue. It is also possible that the OEM fuel pump cannot draw the fuel up high enough as the tank levels drop down.(?)  Isolating each tank will require adding another petcock (which I have) and at least one more fuel line "T".  This set up will end up with a plethora of fuel lines so I think I'll leave "as is" for now.

Got on I-8 and headed East to Dateland AZ  then another 20 miles East to exit
North towards  Hyder AZ. which was a WW2 Military Camp. (click on link) ....a Million Troops trained there according to the "link" info...

Crossed the "Gila River" which is dry most of the time...I suppose a major event will have it running water once a year or so...

Took the old Agua Caliente Road. A local told me years ago that the Hot Springs Resort shut down in the 70's due to loss of the water source....seems that the onset of irrigation of surrounding farmlands upset the aquifer feeding the hot springs and the source gave out...leaving the hot springs dry...

The location now sits boarded up and abandoned. So quiet here...not a sound to be heard.

"Hyder Valley Supply" now out of business.....with the small local population I can't see how any business could survive. Judging from the thousands of empty beer bottles along the miles of road shoulders, bottled beer is a main staple of the locals....picking up the trash is not.

When heading back West, I got off the freeway at the "Mohawk Valley", following the frontage road for the final 60 miles.

Ran across a group of Border Patrol Officers on a hill above an abandoned old gas station location. They had some sort of mobile tower erected, likely looking for illegal people / activities. Did not take a photo of them.
A nice day ride totaling 175 miles. Actually very pretty desert country. The bike worked flawlessly as usual. The Gold Wing likes to lope along at 65 - 75 mph and is happy there....I boosted it up to 90 mph a few times just for fun....Will likely need a new rear tire for next summers riding season as this one is getting a little thin.

Colorado River Ride - Arizona

Took a quick ride up to Quartzsite last week to check out one of the local "Flea Markets". Also wanted to check the highway range of the auxiliary fuel tanks. Riding around town they ran out of fuel at 60 miles. I re-filled them and surprisingly they only took about 2 gallons initial fill showed 2.8 gallons so I think the fuel pump meter was off at the gas station.
I ran to Quartzsite and hit "air" at 80 miles...haven't refilled the tanks yet. Either the tanks are not drawing fuel evenly or their capacity is around a gallon each. I could pull the fuel line off each tank and see if any fuel is remaining. If they are not drawing evenly, I could isolate each tank and add another petcock so each tank has its' own.

I routed the individual fuel tank vent lines up under the seat and they were open.....bought a couple of cheepo one way vent valves and installed them yesterday. /that should reduce any fumes or chances of leaks due to expansion....although I won't over fill the tanks.
I wandered around the largest Flea Market for an hour or so....found a nice set of Heyco, West German end wrenches for 5 bucks. Upon leaving the area, I spied a friend on a Ural Sidecar rig pulling into the Post Office. He and I have a way of crossing paths by chance quite often....this is the 3rd. time we've had this occurrence. I followed him out to his place for a quick visit and looked at his recent completed Gold Wing 1100 model he has redone....very nice bike and spotlessly clean. Also for sale....if I had room for a 4th. bike I would own it.

His "Adventure Rig Options" stir up some attention at the local Border Patrol Check

Took a break near Palo Verde at a Colorado River access point.

More like a lake here....a few folks were fishing.

Worked my way down to Ogilby Road which then leads to I-8. The road is in rough shape.

So I was able to make the 220 (or so) mile loop without adding fuel....should have 1.5 to 2 gallons left in the main tank. Safe range with the added tanks is now at 280 miles. I would normally have to fuel up at Quartzsite to make this loop.

GL1000 Auxillary Tank Plumbing

Got the parts needed to plumb the tanks in the mail late today so hooked everything up:


I purchased two petcock assemblies but the schematic shows using only one....I guess they figure the tanks will draw evenly (?) The additional petcock lined up neatly with the existing one and both are "Horizontal / Off".... For some reason the extra petcock they supplied is opposite with "Horizontal / On".
I'll try it with one petcock and if the tanks don't draw evenly I'll add the second one.
I'll visit the gas station tomorrow and see how much they hold and check for any leaks.

Nice day (78*) in So. AZ. today....(Home / Montana is near zero & below currently - glad I'm not there!) took a nice little 80 mile ride:


Old Mission overlooking the Colorado River.


Large collection of old military tanks / hardware out at the Yuma Army Proving Ground. They have a couple dozen on display....the old WW2 era Sherman Tank directly behind the bike is heavily "Pock marked" with .50 & .30 Caliber hits....must have been a target practice victim back in the day.


Honda GL1000 Auxilary Fuel Tanks

Finally arrived in Yuma AZ. on Dec. 1st. after a long trek down. Caught by some inclement weather in central Nevada but had no issues.
I had delayed preparing the Gold Wing side tanks all Summer and finally had the time to start work on them once we were here.

The Emblems were simply glued in place so came off without a fight. With not much Paint Stripping experience, I purchased a spray can of paint stripper.....the paint partially came loose but they were quite a mess when the can ran empty.....the next day I bought a quart can of "brush on" stripper which worked quite well. After 3 applications all paint was gone...took a lot of scraping & scrubbing but finally was removed.  I then scrubbed them with SOS Pads.....and some fine grit wet sand paper....finally polished them with "Mothers" Aluminum Polish. Not overly shiny but I wanted the "raw" appearance.

I mounted the tanks as I figured they should be mounted but they crowded the foot pegs quite a bit. did not like that at all....found by reversing the tanks there was a lot more foot room and the lower mounting bracket holes were right above the passenger foot peg mounts.

I had a few old BMW Airhead fender washer plates which were the exact length needed. Just had to ream out the holes a bit. I removed the rear passenger pegs as they are never used anyway, but they would still fit if needed.

I found this schematic for plumbing in the tanks somewhere. I order two petcocks as I'm not sure the fuel would draw evenly from the tanks with one outlet?????....maybe some smart Engineer could educate me on that matter.....or I install one petcock and give it a try.....but maybe it would be better to be able to isolate the individual tanks using two petcocks, which I ordered.

Kind of an "Aluminum Overload" in their "Raw" state....I ordered a pair of simple  "Honda" emblems to attach to the sides. Don't think I'll paint the tanks. If I decide to sell them down the line color match won't be an issue.

 One has some minor  "road rash" damage but nothing some alloy filler couldn't fix. Was going to buy some Aluminum "propane only" brazing rod but haven't been able to find any other than on $30.00 + with shipping.
