What kind of assembly should start to put on if i want to get more power of that 09 iqr, but still run the pump gasoline or 100ll ,if its better option than 98e5.

I'm currently buying slp/racedept twin pipes.
motor have 09 cyls and 08 head. And i have 2 cdi box ,but I do not know what they have been.

what about cdi ? racedept reflash? some else?
and what about comp ratio with 100ll ?

the engine is going to my watercross sled.

Common things i see in these 600 sleds are the motor strap bolts backing out of the engine. Make sure you torque them good to specs with proper bolts. I just bought an 09 600 Hi comp twin pipe motor. Sled rips! but i found out only one bolt was holding the motor in. Im at 10,000 ft so i run toluene mixture with 91 and it runs great.
