I'm still pulling 8150-8200 RPMS on top with stock gear and 48-42 helix set at 14lbs. I have 13.6 in middle and 5.2 in heel. I can't add no more weight on tip and I have the stock 160-230 spring in it. Only thing I seen in skidoo race book is a 130-200 and a 100-200. Is that they way to go or should I go with more helix? I would rather not add weight to the middle cause I'm shooting for my buddy's triple. I know I shouldn't be with a twin but I am.
I also could try my 27 tooth top sprocket also.

MidMich800twin,

Take some weight out of the tip and place it in the middle,  also back the spring pressure off on the secondary.  The 160-230 spring is fine.  You just need to change the weight setting around a little.

I'm on my way to try.... You the man GLH
Never dreamed I would have to lighten the secondary up even more but i'll take your word for it.
Thanks
