Topic: Tuning CR31's for 836

[jman19]

Hey Everyone,

I am brand new to the forum and am so greatful for all of your help. I have a 72 750 with an 836 kit. I have a RC 315 cam in it with a ported head.

My CR 31 Specials arrived on Friday. Obviously I would have gone with 29's if I could have. So my question is does any have suggestions as to what adjustments I need to make to the carbs for maximum performance. Currently 120 mains with the needle clip dead center out of the box.

Help Please,
Josh

I run 31s with the same set up although mine are a bit rich on the bottom. 120 mains and needle in the middle
they are very close but I will get he bike over to the dyno to do some fine tuning.

Great carbs

Jim
