Ideal clutching for 2011 std RMK extended to 163"?

[backman]

Hi
Got a 2011 155" refreshed top end with Wössner and VF3R. Running with std secondary with black/purple spring, primary 11-68 blue-pink spring. Geared 19-42. Running at low altitude 0-1000 ft and with this setup it revs 83-8400. Now, i am extending this machine to 163 with a CE2.5. Any changes i really must do in my clutching? Any suggestions for improvements ?

gear it down to 19-45 and leave the clutching as is.

My 11 163 CE 2.5 likes that gearing.
Low altitude.


A 62-42-.36 helix wouldn't hurt.
Load that midrange a bit.
