Re: R69s Tire Pressure

One way of testing your tyre pressures is with a digital temp gauge.

The tyres should not be building up excessive heat above ambient temperature.

On my 4x4 when travelling I have tyre pressure sensors and I adjust the tyre pressures if the heat builds up.


Just a thought.

Re: custom made Clutch push rod

That is interesting what you say about the Ducati's.

If this design fails then I guess a different approach can be tried.

Any suggestions are of course welcome.

Re: custom made Clutch push rod

Re: Anyone have Mark Huggett mufflers?

I have a set of Mark Huggett R69s mufflers. While I cant vouche for the internals, I weighed one muffler at 3.5Kgs. So obviously there is something in there. They are dignified and quiet as I always remember a BMW to be. Your call, or email Mark and ask him. He is a very knowledgeable fellow and I b...

I tapped a small thread into the bottom oil pump gear and use a small screw to retain the gear during assembly. Not essential of course, but I find with the case hot and all the o...

I have given up searching and figure if one comes along, well it is meant to be. Just dont want some clapped out high mileage bike that I ha...
