I have heard of stock cylinders makin quite a bit of when worked over. Sandtrix has a stock cylinder in a drag frame and its pretty damn quick. Setup makes or breaks anything

 

i have read reports of a stock 250r doing 34hp.a guy on one of those other forums said his esr 310 cylinder 250r dynoed at about 53hp with the type 11 drag porting.who knows..

 

well i know talkin a car or truck the hp can change drastically from crank to wheels, but on a quad is there a huge difference, i have more experience on larger machines,

10 percent ish, that's a lot when your talkin 50 to 80 hp

 

I think stock was 27 or 28. Not sure if that was at the crank or the rear wheels. It is important to make that distinction. CT claims their 350's make 58 rwhp without anything fancy. Basically 50/50 race gas, mx porting, pipe, and 38 or 39mm carb.
