I have PSI pipes,clutch kit Vforce2s,36mcarbs bored to 38.5m. Tried PSI for info always busy signal talked with tech once. Apparently I caught him on a bad day :hallo1: Any info would be great..

not alot of info to work with but ill get you in the right direction, psi wanted you to buy there clutch kit for the pipes right? dont know how much but if youre gonna try it yourself your gonna spend more in the long run and may never get it right, there pipes will probably have to be tuned to operate properly at 9200 rpm, stock was 8200. youre given up power on low rpm gaining on top rpm, so lighter weights maybe 52grams stiffer drive spring like a 170-330 or 350 engagement at least 5000 driven a 57-51helix mayde a cat redwhite spring set a lil stiff, lets change the 52s for say 50s bored carb can be a nightmare, stock jets were 350 id try there they were to fat anyway, now you see the cost of all this its a guess psi tests it all and when it comes in a box you just put it on.
