srx 151, it want climb

[srx 700 151]

I have a 1998 srx 700 that I have been long tracking to 151"/2".
Gearing:20-40
stock engine and secundary clutch(yellow-white-yellow)/43deg helix/ 80deg.
My primary: stock yamaha clutch (green spring), whith A-1 comet clutch weight in it.
The sled is ok, but not fast up to 50 mph,after that it is very slow.The engine rpm seem to be ok at about 8500.In deep snow it`s slow too.
Is there anyone who knows what is wrong with it,ore what i could do to get climb in the mountains

I would give Tom a call.

I would either check your springs or check your wording, ...I believe the green should go on the secondary (helix end) and the YWY should go on the primary (weight end).
