This winter i want to go big bore but duno what i need or how much its going to cost. I want to go with an Nmotion cylinder not sure with a piston, i run 110 already so having a 12:1 piston is just wasting my money really.


So how much money for each bore?

I would say the engine is built to handle the power the way i have it now, maybe not?

call kbr on the n motion cylinder. i talked to kam before i found my athena and they did'nt have any ready to ship at that time. so, a call ahead of time may ensure you get it when you want it. they're not cheap.

if your running race fuel, you may as well have a 13:1 or up piston. with the big bore, your gonna need a new slug anyway. the cost should be the same stock bore or big.

a 97mm bore would make you a 501.

with a 97mm bore would make ya 501 and piston price would be same either one you chose (big bore, stock bore-low comp, high comp) the cylinder is what your going to have to pay for because stock cylinder wont hold stroker cranks when bored out

i'll keep that in my head, i need to figure out how much it would cost for a 501 or 511 and decide then.

The price of your 490 makes it tempting though!
