Re: Changing gearbox, r75/5

Ok! Good to hear!

The linkage and all fit on my /5 but i really dont like it, feels sloppy and has play in it. Ill rather just have a shifter that goes straight in the transmission. So now i just need to find a shifter.. :)

Re: Strange problem with ignition timing

Thanks for the help!

Random dancing, not the two marks usually seen when the cam tip is bent. A crank mounted ignition is not an option for this bike. I cant see the F mark at all. When the timing is fully set on one side i can just barely see the F mark but its way out of reach for an adjustment to fix it. I would have...
