Trying to find out what RPM to clutch this new motor with.I can't get a hold of Bender . On a stock motor Bender recomends 8750. With this new 780 it's been trail ported, mega power head, etc. Bikeman is not giving me specific info on peak torque and peak hp RPM becuase they don't seen to know to much about Bender pipes. If anyone has peak torque and hp for a 780 ( any 780 ) it would help!
Thanks Steve

Arn't the pipes only good up to a certain RPM, even with porting and or mods?Imho Porting only helps the motor breathe better, there by making more hp and torque(getting the work done more efficiently) in the "normal" power ranges. T
Bender big bore pipes should run at 8300 to 8600. 8300 short pull 85-8600 long pull.
