Picked up a set of benders a couple of weeks ago , just got new gaskets and jets 50/150s ride at around 1000 ft. Weather is getting warmer (9deg today) and sled is running great , stock other than reeds . Searched through the forums and cant seem to find much on a clutch setup for me , don`t want to waste last bit of winter trying out testing clutch setups. The one i did see used 8-ca weights with no rivets ,o-p-o primary spring , stock secondary spring and helix @ 70deg wrap. Any help would be awesome , tks .

Check out the tech pages for clutch set ups.
if there is i cant find one , that one i found from a old post 2003 . Everything else is higher elevation ,gearing changed , or aftermarket helixs
I have the bender paperwork for those pipes, send me a pm with your email and I will send the info to you.
thanks srx1000 , just what i was looking for
