So I recently acquired a crf 150.. mind you I'm 6 foot and weigh about 175. But hey it was 300 bucks. So when I got it burned oil like a mother, and only had 50 psi compression (surprised it still ran!) Any who ripped it apart and found : bent exh valve, Piston to cylinder clearance way to much.. so I'm looking at piston kit, cylinder, new exhaust valve and probably new guide.. question is my size.. rebuild and sell and get bigger bike? Or big bore it and beef suspension to handle my weight. I have an r6 so that takes care of my need for speed. Just looking for something that's slightly competitive and fun to ride! Any input would be great!
