Hello Gents, I haven't posted in awhile but its time for me to do some refreshing of my FX motor and I am thinking about increasing the displacement.
I am wondering what the next logical bore size is, and what cc that would ultimately be. I guess one thought is a 570cc sized piston on my stock 450 stroke, I am not sure what that would end up being in displacement, or if that is a combination of parts that is a good idea or not. Also would I have my cylinder bored out and resealed or would I want to buy a different cylinder in the correct size?
This FX is my trail bike but it has a license plate and does some road riding to and from the trails. I changed the transmission to FE gears and am currently running 14/52, hoping with a little more torque from the engine I can run 14/50.
Back to the motor rebuild, this unit has about 225 hours on it. I plan on a new piston (the opportunity to go bigger). I am wondering if it would be wise to do crank and rod bearings too instead of just freshening up the top end.
Appreciate any wisdom!
