At least at the moment, and already for years, there are no pistons for the 19mm Grimeca

I have been. Currently rebuilding both Borranni rims, new stainless spokes, nipples and doing a silly amount of cleaning. Update soon.norbert wrote:Fine, so get on with that project
Sounds like the clutch might need 'shimming'.Paz2112 wrote: So I was unable to use my colourtune to correctly set the mixture, somewhere along the way I have lost the HT lead from the box. Thankfully Gunson were very helpful and a replacement lead is now on the way. With this and the balanacers I hope to get the carbs close to perfect next week. I suspect however that the clutch is going to need a closer look. Any suggestions on what else to look at? I have a tiny amount of drag when the bike first starts (back wheel rotates slowly) but it stops after a few minutes. Clutch is adjusted correctly as far as i can tell. It does also feel quite short when pulling away.
