I installed tbolt 141 bbk, now the bike is making a loud sound and broke valve rocker. I bought a new head hoping that would be an easy fix I timed it with t mark and notch on head. Should be perfect. I adjusted valve clearance 0.03 and 0.04. still making the noise don't know what to do at this point. Don't want to put old jug on just to find out it didn't fix anything. Anyone else know what it could be it's not timing and it's not valves. What could be the fix? Is the piston hitting valves? when I replaced head the piston looked fine.
