1977 'garage find' R100s

Let's go for a ride

Mike,

Bike looks great. Can't wait to see it in person and go for a ride together. I've got mine sorted out and I'm enjoying the airhead experience.

Can you email a photo of bicycle?
if you are interested a friend knows everything about vintage bicycles.

I also just drove a 1978 S home that is in line for Inspection what I got.
 
Well - completed the final items on the 'To Do' list to get the bike on the road. My friend, Brian Tinkler (owns the beautifully restored 1979 RT - transformed into an 'S' by him above, and knowledgeable wrench/airhead) - offered his services and stopped by the house Saturday. I was planning on pulling the trans to lube the clutch splines. It was suggested (by Brian and Valdi at Valdi's Motozone) that since the trans will be out might as well replace the rear main seal and oil pump 'O' ring - since the bike has been in non operational status for so long. Thanks again to Brian's expertise, and assistance (he did most of the work) these tasks were accomplished Saturday by around noon. I put things all back together, changed all the fluids, and Sunday morning fired the beast up. What a sight when I installed the battery and turned the key on and the electrics came to life after a 25 yr. hibernation, beautiful. She fired up relative quickly, blew a lot of carbon our of the pipes, there was quite a bit of soot covering the garage floor. I rode her briefly down to the gas station (no plates or registration yet) to get some gas in her. She didn't run all that well though (at idle and low RPM's), and it is carb related. I rebuilt both of the carbs and set them up with basic stings, per Bing instructions. The bike when warm idled too fast and was slow to drop RPM's when the throttle was released - the trouble shooting section in the Bing Manual states that this is probably due to an air/vacuum leak (usually at the cylinder side of the carb). Everything looks as though it is tight and leak free. Over 3,000 RPM she seemed to run well - I realize this is on the main jet vs. the idle jet. I need to visit Snowbum's site and do a little research. Any suggestions for this rookie?

Also, when cleaning up found the work area found the below two rubber pieces (both are rubber), any idea where they are from. Did see them when we were taking things apart, might have been on the floor and come from something else. At any rate, I'm getting real close to having this beauty on the road in her former glory real soon!

Was anyone "helping" you work on the bike? I once "helped" a friend rebuild a carb from a Mustang. I had a few carb parts left over from rebuilding other carbs, so I snuck a few in his pile of parts on the floor. After I left he spent a hour trying to remember where those parts went, I never did tell him about it. That said, I do not recognize those parts from any BMW that I have owned.

I don't think the rubber parts are off of the bike - I have 3 kids so who knows. As far as the carb rebuild I did them myself. I bought the rebuild kits along with the Bing Manual and a 'How To' DVD from Bing. Actually, the rebuild was pretty simple with the step by step in the DVD. Anybody with a modicum of mechanical ability could do it IMHO, with the DVD, a few basic tools, and a gallon of carb/parts cleaner. Now getting the carbs set up, another story - will keep you posted on that one.

Did you remove butterfly & replace oring?
I believe it was a oring, never went that far curious if that is doable with DVD or manual.

Yes, removed the butterfly and replaced O ring - was relatively easy to do. Again, well explained and demonstrated in the DVD. I took the carbs completely apart and reassembled with #6 (complete) rebuild kits from Bing.

I think people are making a mountain out of a mole hill here. Yes, if you don't get the butterfly installed properly, it could be a problem. But, I don't think it's that difficult to do. It takes time and patience. I typically stare at the sky (on a bright day), and keep adjusting the butterfly until I see no or next to no light coming through around the sides. I keep pressure on the butterfly so it won't move, then I install the screws. I check again to make sure that the butterfly didn't move. It's a bit time consuming, but it's pretty straight forward.

Thanks have always avoided that butterfly will get the kit & DVD.
