Re: Lightened flywheel

Hello Charles That looks like a good clean-up job on the teeth, I expect it will make a good fix. a few years ago I had my bike come back from the MOT test with a broken starter nose-casting - the MOT guys had "road-tested" my bike (I think a bit like the garage attendants in Ferris Buelle...

Re: R90/6 project

Hello Chuey, I am sorry I didn't reply, I didn't see your edit until now - nine months later.. The intake suck must work in a similar way to that of the exhaust, using the exhaust to pump down the crankcase means that the engine doesn't have to burn the oil mist though. I opened this page as the R90...

Re: Wishes for Christmas and the New Year

Hello Rob,
I'm not planning to go there again for the foreseeable future, so I'm around. I'd really like to go out for a ride soon if you are on for it. Weather depending as I am a fair weather rider. Best wishes to you and your family. Sam

Re: R90/6 project

Thanks for the encouragement Brad. The front fork/brake work is Jim Cray's. He is a really good engineer and tuner. Charles (chasbmw) has had work done by him too. Sam

Re: R90/6 project

Hello Brad, The oil system is based on the idea that a slight vacuum in the crankcase allows the pistons to descend without costing so much power, deals with leaks which can be caused by excessive crankcase pressure and returns oil which is blown out of the breather. It is based on work done by Udo ...

Re: R90/6 project

Hello, a quick update on my slow progress with the R90/6: Jim Cray collected my bike yesterday to give it a look over and prepare it for the UK MOT test (certificate of roadworthiness). I left the air-box off as Jim will be re-jetting and synching the carbs and I'll fit the front mudguard when I hav...

The oil tank is moving on all I need to do is to plumb in the hard lines to connect the exhaust sucker valves (red and green knobs) to the reed (under that cone at the top r...

Re: R90/6 Back on the road=))

True Tim, though rather than tapping them out, they could just have clearance holes for M8 bolts. However, the fork legs would need to be set up in a milling machine and have cuts made for the bosses to position in (as per the spacing on the fork brace/mudguard bridge), then welded. the alignment of...
