I'm tearing down my scrammie lost the fricking piston skirt. It's a Art piston and has an AAEN pipe. I'm trying to figure out the last owner had done to it. The head looks like a he sharped the edges. Does anyone know what comes stock in the clutches it currently has a blue (drive) and a red Secondary (gear case).

 

secondary should be red, but primary i cant answer since i dont know what bike your have, the 400 i believe came with white, and the 500 came with plain.
let us know what bike you have and year and someone will know.

i too lost a piston on my bike and i recommend you replace it with a wiseco, i did and have had no problems since.
good luck

 

Sorry it's the 400 4x4

 

then it should have come with a white primary, mine did from the factory, but i have a 2x4 400, the secondary should be red.

good luck bro.

 

The early 400 scrammy had the blue/green primary and red secondary.Bet his is stock because the Aaen spring kit is ussually a green primary (about like a brown polaris)and thier blue secondary.

 

brad your right cause when i bought my aaen top end aaen rec. using their green primary and blue primary. so obviously he has the aaen clutch kit and pipe!
