Thanks for the opinions but I'm shocked at how much this could cost. I'm not talking bout 4 to 5mm I'm just thinking 2. And keep it stock maybe .20 over on bore and nice port work to line up with the ports. I got a 3mil 240 blaster back in VA. Didn't need a trenching to cases, but I know it could be a more affordable way to customize a lil stroke increase. And to make up rpm I would get vforce reeds shearer pipe and gear changes plus a pwk or pj carb. It would take a lot of comparing other cranks and motors to see if it can really work. And y'all right aftermarket just never praise suzuki enough to up some hp.
