srx 600 clutching

[swede srx]

My srx 600 overrevs, about 9000-9200rpm.
I made race logic porting,cut heads .010 and change my inner rivets from 3.1 to 4.5. The change of rivets made almost no difference at all, maybe it load the engine a little more at low speeds. I have a 1.5" track (camoplast 9803) everything else stock. Suggestions? rx-1 51/43 helix?

8bu-00 weights, 1st hole empty 2.4 gram rivet in tip, 45/39 helix silver secondary spring at 60 wrap. 51/43 won,t change rpm,s.

Thanks Turk, will I still have a good backshift with this setup?

Backshift will be OK as long as you don,t go off trail. If you want better backshift run some 8dn-20 weights with a 51/43 helix with about a 2.4 gram inner & outer rivet.
