clutch engagement and full rpm


yeh i know but its a yamaha site 92 and up carbed 650 used rxl cyl that made them more tempermental advanced port timing did not work as good as earlier years
 
I Can't remember the rest but I know you want to use M1 weights. At least thats what ran best with my buddies piped machines

motor all stock just didnt know the rpm of those motor ....don;t worry i know its a yammy site but alots of people nkow good things here
 
Stock 92 would engage at 4K and run 8-8200 with the stock pipe, they are a little lazy down low so if you get it to engage at 45-48 it will be better.
