Depends on what ur looking for. After my build i found that ny motor drank gas AND i was running 110. Not a good combo on a trail motor. So i switched to pump gas ( from 180 psi to 150) and went to stockers. Lost some peak hp and a little torque but who cares? Still 70+ hp and 40+ torque on an unported motor and my gas milage rocks now. Dont be afraid to run the 28s. If u do run the 35s dont set it up for race gas like i did.
