Trans-Shaft Bolts

Post by ksiemon »

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.

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 !!

Even Grudging Approval is Nice

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.

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

Progress

Post by skychs »

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 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

Post by khittner »

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.

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.

I saw the early and late model seats but they also have two identical looking ribbed seats, 1975 and later. I think they called one premium and one standard. The difference could be the quality of the seat cover or the pad. It doesn’t differentiate.

I guess I need to give them a call.

Sargent seat has really disappointed me on this one.

Seat

Post by skychs »

Progress on the build today. The long awaited seat finally arrived from Moto-Bins in the UK. Cost .... 273.99 GBP or $382.77 delivered in 3 days. Now thats service. IMHO the quality is top notch. New pan, foam, seat cover, rubber pads, everything but the two hinges which I already had. Once installed everything lined up. The pin striping matches and the seat lock works like a charm. Photos from the day.

Thanks Khittner for the advise !!!

Now its back to the electrical harness. Grrrrrrrrr

Side covers

Post by skychs »

Question .........
The battery box went in today so I installed the side covers to check the fit. The side covers just slide in the groves on the frame and are connected/held in via a rubber band? Am I missing something here? Should there be some kind of rubber bumpers or modifications to the frame slots so the covers will not rattle around? What a horrible fit.

Any suggestions on how to secure the side covers so they don't move around and rattle?
