Rev counter on my K1 is similar in that it's fine to 5k than just jumps around when above this. Built it out of the best bits of two a year ago and its just been taped together this year as I was trying it out. But just about to look inside again.Is it just a matter of cleaning or is further dismantling necessary or is it likely to be a problem with the damping pot? (it's fairly smooth up and down to 5k.)
