there are a few things taht bug me about that...
1 "exhalent" if the dude spells like that I don't want him near my motor.
2, there are no real details on that site, I couldn't find any info on what the sleave is made out of.
3, that crank weld at the pin sucks
4, there is no intake cutout on that piston they use...shitty...

Glen at GSS used to do bigger bore conversions, I would trust him way more.

I'm hearing there are some of these starting to appear on the kart stuff that I do... There is a 550 cc limit, but whats rules? The people that are supposedly running them are constantly ventilating pistons/blowing up.

i wish they would shut the site down and quit advertising, or put up some concrete proof of their work in action . some "real" photos, a youtube video or other proof their stuff actually runs, and maybe a dyno paper showing thier claim of 115hp....then i might be a believer . at this point, its nothing more than smoke and mirrors as far as im concerned

How can anyone take your advice when you can't spell sleeve?
