I recently got a 89 phazer and rebuilt the motor, secondary clutch, replaced the primary clutch, and the breaks, belt and track. I want to set it up a little better for the trails so a high top speed really isn't that important to me. I want it to be a little quicker in the trails. I have 96 studs on it, and am thinking about installing a stiffer clutch spring, but what do you guys that have phazers set up for trail riding run as gears in your crankcase, and does it really help it out much? I just want it to pull a little harder coming out of corners and up hills. I appreciate any help, and safe riding.
