I’ve got some TM K11B’s collecting dust since my local track put in a clutched karts only rule
Putting a clutch on them was not an option without putting in a JICA crank half. Then I stumbled upon the jackshaft… all problems potentially solved.
Though I have some questions on the best way to go about it.
I normally run 10t front and 80-85t rear. My first thought was put 10t either side of the jackshaft, but this would result in the clutch running at up to 20,000rpm! So I was wondering, should I gear it down to reduce the clutch rpm?
A lot of people run Yamaha KT100s here (I'm in Australia), so a clutch to suit one of these would probably be best for replacement parts … most are centrifugal, though there is also the Tomar (have never used such a clutch so no idea if they are suitable for 15000rpm+).
Anyone have an idea on the best approach for implementing a jackshaft on a high-rpm motor?
