hey guys i bought this cylinder about 15 years ago from trenga. it works really well. im not sure what category porting was done to it. it also has boost ports in the exhaust. can these be ported any further or is this pretty much a drag port??

it was sold to me a long time ago from trenga before they went out of business. it was called "ultimate 200cc cylinder" our porting looks very identical but urs says its 225cc? either way could our cylinders be ported any more then they are??

To certain point yes. Majority of power is made with exhaust port. You need to measure degrees open and width of main port. It all depends on use? Trails, Mx, drag ? Also because it’s plated makes it more difficult.
