i still have my old cats and i was thinking if i could get my cylinders bored out to an 800cc. i see that psi has it for the 700. since all the brands have 800cc`s now there should not be a prob. getting pistons.but i was just wondering if anyone has seen these kits or how to get a hold of weisco for these questions.i am thinking of taking the old crate out of retierment .by todays standards it is kindda light now....lol... my engine can not be ported anymore. it has [email protected] and 91lbs of torque. so if i could sqeese out another 10 -15hp plus adding the ufo`s for a fiew more it just might be competive on asphalt in the 660
