front forks

When you removed the fork tubes from the fork clamp, how did you go about it? I was reluctant to "pry" the clamp after I loosened the bolts.

Forks and wheels

All I had to do was loosen the bolts ..... then I took a medium size regular screw driver and lightly tapped it into the fork clamp gap to open it just a little bit. The two tubes fell right out.

Today I had the chance to check the front wheel. The arrow was right where you said it would be, around the stem hole. Luckily for me the arrow on the wheel and the front tire were in the same direction. All I had to do was replace the stem plug and fill it up. Im so happy I didn't have to take everything apart again and start over.

The rotors are now on the wheel and snugged up to 18 Ft.lbs.

The only Service/repair/maintenance manual I have is the Clymer BMW R-Series . 1970-1994 M502.

I would use a piece of wood

I would use a piece of wood as a wedge to open up the gap.

Progress

Progress in the shop today ......

The front end is in ... not all buttoned up but in place and looking good. The front wheel is on. The shocks are in. Calipers and rotors are on. The pads will go in once I get the master cylinder and lines finished. For fun I threw on the front fender. SMILES !!

Here are the photos of the front brake master cylinder. Yuk. Nasty. It all cleaned up so Im not too disappointed. I found some O-rings but I will still need to replace the two seals. I love it when this stuff comes out nasty and ends up looking like new.

Do I paint or powder coat the master cylinder? With brake fluid Im thinking a good powder coat will hold up better.

rear wheel

Progress on the rear wheel. It came back from being blasted. Cleans up fairly well but its a PITA polishing it. I slapped the temporary handlebars on it so its now a rolling chassis again with new rubber. Looked funny with the wheel and no tire. Smile

Note: Even the rear wheel has an arrow for direction of roll. Imagine that. Kind-of obvious isn't it?

The plan now is to roll the bike off the lift and start working on cleaning up the engine. Its not too bad but I wanted to do as much as I can before I slide it back in the frame.

Rolling Chassis

Certain stages of a rebuild are very memorable. Rolling it out of the garage the first time is one of them. I even got a smile from the wife.

The front brake master cylinder is also back on the bike. If this thing drips as much as one tiny drop of fluid Im upgrading it to the next version. I hate brake fluid. Smile

Motor

I have been on vacation so progress has been slow. However, this morning I was able to install the engine. Soooo much easier without the transmission attached. I assume the tranny will go in easy peasy right? Anything Im missing here?

Now its back to work and the R90S sits for another week.

Trans-Shaft Bolts

I't been awhile but I remember pulling the swing arm pins out and pulling it back into the fender for more room. Others here may have a better way. Also the new shaft bolts are different and do away with the lock washers. Some of the locks have broke, so they recommend
using the new stuff.

Work and more Work...... so we can get, and work on more Bikes!

Your right. It shouldn't be too bad. I just need a little extra room. On the R60/2 I just had to tilt the engine up and forward. I may try that first just to see.

I have the new bolts (no washers) for the drive shaft. Everything right now is just in place and not tightened down.

Tranny

Its in. All I did was pull the swing arm pins. It laid back just enough to slide the tranny right in. Lining the splines up was the hardest part. Electrical harness is next. Oh Boy !!

Daytona Orange works that way, even with most spouses' cold and hardened hearts.

Progress

Good progress this weekend. The electrical system is going in fine. The only glitch so far is not having the turn signal wires routed before I put the front end together. Grrrrr.

The body work is coming together. Im really happy with the progress and hope to have more to install when I get back from work next week. I ordered a seat from Sargent early "last" December and have yet to receive it. I may have to go to sMeyer from Germany to finish the seat tray. They have two different seats but I'm still not sure what the difference it. There is very little description on their products.

Here are some photos from the weekend. Im not building a show bike. Im building a bike to ride. I want it to look nice and run well but Im not really concerned about it being a perfect replica from the factory in 1975. Id rather the bike have character than look like every other R90S.

The more I work on it the more excited I get. If all goes well I plan on having this bike on the street before the end of March.

Looks good from here. Nice

Looks good from here. Nice work. Went to my shop today for about 1 hr. Then started to snow some. So rather be inside in front of the boob tube. Then I took a power nap for 2 hrs.

90S Seat Covers

There were two different seat cover patterns for the R90S, which probably explains the two seat options from Meyer. The '74-only cover was plainer, and had essentially two big rectangles embossed in the cover. The '75 and '76 bikes had a cover that had ribs embossed in the cover across both the rider and passenger portions of it. This later cover continued to be used for later bikes with cowled seats through the mid-80s. Your bike would "properly" use the later-pattern cover.
