When in to A dealer that is A Team dealer and they couldnt match the numbers that are stamped on it or couldnt tell me what helix and spring I should use.The build date is "02" the numbers that are stamped on it are US Pantent#6120399 and then there is 3 sets of numbers 420313 111802 00287.Also its painted red.I bought from A guy who says it was on A 01 800 xc.The mods I have on my sled -V Force reeds,heel clicker clutch kit,SLP single pipe,studs.I would like to set it up to my type of riding, we do alot of drag racing,whole shots and top end, is there a helix anyone can suggest?

The spring they recommend is a Black/red - 140-240lbs
The Helix is a 66-42.46- 66-44.46 twin trax helix.

However, with your heelclickers, you may have to play around with the secondary spring. 140/240 may cause overshift because of how quick the clutch upshifts and how aggressive the weights are near the beginning. I would go to a Black/purple (160-240) or even a black/white. (160-260).

I'd buy a few different springs and try them. I wouldn't bother trying the 140/240. It will most likely be too weak. Heelclicker does favour a lower angled helix. YOu may even get away with a 58-44. You have the ability to load your heel with as much weight as you want to compensate for any overev out of the hole. I'd start with their recommended helix as a starting point - but I wouldn't use the spring.
