Re: R90S Flywheel Ring Gear?

RealOEM says that part number 11221256966 was used on all /5 and /6 bikes 1969 - 9/1975. There was a different part number for /7-on through 1980. Seems like there were some issues with the size of the bolts/holes into the crankshaft for the early bikes. Not to mention that the timing marks changed ...

Re: R69S battery

I did something similar with a battery from Bench Mark Works. it's basically a UPS battery with those spade terminals. I had to use some wood to shim the battery to sit better in the tray so the rubber strap would hold it. I went to an electronics store to pick up some quick disconnect wiring like u...

Micha -

No I don't. You would probably need to start with Mr. Google and see what you can find.

Re: R90S Flywheel Ring Gear?

Yes it is heat shrunk or possibly staked to the outside of the flywheel. Have not heard that people have tried to replace just the ring gear...I suspect the way to go is to buy a new/used flywheel.

Re: Petrol Tank Internal Coats questions - Paint & Sealer

Michael - I guess I'm the one that doesn't understand! I think that either situation you mention the solution is the same. You must first get the interior of the tank rust free by using some sort of method to etch or kill the rust...plus getting rid of any left over debris. The final step then is to...

Re: Petrol Tank Internal Coats questions - Paint & Sealer

I wasn't aware of a paint application over a sealer. Usually one would etch and/or clean the inside of the tank and then apply a sealer. I've heard of POR-15 as well as one supplied by Caswell Plating. Snowbum discusses gas tank cleaning and sealing on this page: https://bmwmotorcycletech.info/fuelm...

Re: /2 service

I doubt there is a controlled experiment that will show how slingers fill up these days with the newer oils. But my understanding is that it comes down to particulates that are captured in the oil. Any engine is going to create by-products of combustion some of which will end up in the oil. In the o...
