After 58 years riding and so many bikes the time has come for me to call it quits and it is far earlier than I expected but my health c...

Re: Break-in oil

I use Brad Penn 30W break-in oil with new rings or with something that sat for a while (like 30 years!). It stays in the motor for the first tank of gas or so, 200ish miles. Break-in riding is mostly accelerating and decelerating in gear, up and down, from 2K rpm to about 6K rpm. This has worked we...

Re: Neutral Light stays on when clutch pulled in

My apologies, I think I may have misread the original post. The way I read it, the neutral lamp was working exactly opposite to the way it should be. Re-reading, I don't think this is the case... so The correct function of the neutral lamp is that it should be on when the gearbox is in neutral and ...

Re: That's AI for you

I got so fed up with Google AI I have managed to turn it off in Google Chrome, it's a worry when you are trying to find real true information.

I was hearing a clicking noise from one of my engine heads, so, at the suggestion of my friend, who has much more experience with BMW bikes, we took off the oil sump to see if there was a potential clog.
