just got my motor bak from bms and today was the first ride on the new motor ..after giving to motor time to break in i was on my 3rd 15 min moto and the motor made a big grinding noise and quit running so when i got bak to the house i started taking the motor apart i found it had jumped time by about 4 teeth intake and exhaust ........so i took the head off to check the valves and piston.....so my ? is the shims aand caps on the ex. valves come off easy (normal) but the shims and caps on the intake valves will not come off ( not normal ) so if anybody would no y i would be thankful to find out any info i can .
