Hi all,
I wonder if any of you could helpme, whilst out on my Sunday ride I noticed a hestation at 11500rpm , it's more apparent in 4,5,6 gear than the lower ones ! My bike is an nc23 rrk but it has an rrj cdi fitted to it. It's only started this weekend which is puzzling me

The bike had been in storage and in a very neglected state ,until it was rebuilt over the last winter. It's had a full carb clean and service under a 1000km ago!

Any ideas to what could be causing it?

Hiya, Has it got the standard can and jetting etc?

Yes standard can and jetting, the only change is in the cdi and the gearing , i've gone up one tooth on the back to 41, that's all!!

Could be because you are 18 stone now. (sorry andy)
