i have a 01 pro x 440 with a 800 non ves engine in it it hasv force reeds, slp boost bottle, no air box, slp twin pipes, and slp cheater head. i keep blowing belts at top end so i took the clutches of to see what they had and to replace the springs but there odd colors. the primary is a purple spring with 10-64 wights and the secoundary is what looks like white/ blue but i gess could be called silver/blue and all i could find on the helix was 55-48/36 on it. any one have any sugestions. i would like to replace the springs if i can find them. but also why do you think it blows belts only on top end after been at 8200 for a minute or more. other wise the belts look fine and last fine

Your blowing belts due to heat building in the clutches at wfo.the heat is due to slippage.Try a polaris almond 140-330 in the primary and a p[olaris blue/orange in the secondary.Sounds like an SLP helix.Also you need to verify your clutch alignment,off set and belt deflection.Set your torque stop to just touch the motor once alignment is verified.What gearing are you running the 440 gearing or did you change it.
