Tapp blowing belts compared to stock primary

[max rolph]

sooo in the adapt sec and boss is ron switching to a tortional spring?? from a compression that is stock in both. i dont know if adapt is factory compression or tortional.

Both adapt and boss come from the factory as compression and Ron’s set up for both clutches is torsional. He includes a carbide drill bit and a template so you can drill a few holes in your roller hub and you also drill one hole in the clutch next to where the Tang goes for the factory compression spring.
