My "new" project bike - 76 R90/6

Here's my new bike (well new to me anyway).

Amazing shape for a 36 year old machine with 95,000 miles which hasn't been on the road for 10 years. There is a bit of rust in the tank which I will line with Kreem. I've ordered the parts to rebuild the petcocks and gaskets for all the fluid changes. Once I have the carbs rebuilt and install a new battery I'll see if I can get it going.

Nice bike Bill. I bet you just want to spin that front wheel and watch it go on an on and on! At least my R50 did ... maybe the disk brake models don't turn as long. Have fun!

Nice find.......welcome to the airhead community.

Nice one. It'll be nice to see/hear it running.

Thanks Dino, I'm looking forward to working on and maintaining this vintage motorcycle. Seems that the airhead owners are die hard enthusiasts; I'm getting that way myself and just getting started

When we get it on the road you'll have to take it for a spin.

And here's mine. A 1974 R90S, Silver Smoke. On the road last weekend for the Airhead ride. 38+ years 148+K MILES, that old way of measuring distance. Congrats on your acquisition. It'll be good to get the '76 R90/6 back on the road. Thanks to the care of this bike by the PO it should be on the road soon.

Congratulations Bill.Nice find,it appears that you have an excellent starting point.Airheads are simple by choice,and there is a wealth of information and experience within the membership.Looking forward to seeing it on the road in the near future.Ken J.

Purty bike Bill !
I'm sure BMW still has the highest percentage of bikes built before 1990 that are still on the road.

When you rebuild the carbs, check out http://www.bingcarburetor.com/bmw/bmw.html

If you call them with the numbers on the side of the carbs, they'll be able to provide you with all the parts you will need and at a fraction of the price at the dealer.

I've been told the R90 is the smoothest running airhead, though my R75/5 is pretty smooth.

Be nice to see you and the bike on the road.

Thanks for this NSKayaker. Do you know where they are from? US or Europe?

Hi Willard,

They are in the US (Kansas) and the shipping is minimal by US Postal Service (USPS). Their phone number is 620-767-7845. Don't bother trying to email - I tried that and didn't get any response. Just call them and things go quite smoothly as long as you have the numbers that are on the side of the carbs. I found them good to deal with.

They seem to have a good stock on hand as they are the Bing agent for North America, South America and Australia.

As an aside, if you're replacing the carb floats, you might like to pay a bit extra and get the alcohol resistant ones. I replaced everything except the jets a couple of years ago but didn't get the alcohol resistant floats. Hindsight being 20/20, I think it might have been a good idea. Our premium fuel in NS doesn't have alcohol in it, nor will it I understand, but if you take the bike to the US some of their fuel does.

Also, check the vacuum tube on the side of the carb (small tube sticking out with a bolt in the end) and if it is loose, replace it. It's a press fitting. It's a vacuum line that you can attach a manometer to for tuning and balancing the carbs. I have a Carbtune Pro and I've found it to be great for setting up the carbs and fine tuning.

If you'd like to chat about this some time, feel free to give me a call (829-2805)

Cheers,

Alan

Here are a few photos of the R90/6. The carbs have been rebuilt, forks have been updated with RaceTech springs and emmulators, new battery installed, brake master cylinder rebuilt, new Corbin saddle, sealed gas tank and rebuilt petcocks, and new tires and tubes. New brake pads on their way from Max's.

I've very pleased with how everything turned out. Classic airhead ride - cool!

Looking good bill. New seat too?
