hi ppl

i put 285t2 cam kit on my rst 5 days ago went to power enginnering get it tuned, they got on to the rollers and started to look at my engine and was listening to the engine they took the rocker cover off pulled 4 of the follwers out they told me the followers were faulty, iv had the followers and the camshaft taken out to send back to piper but iv noticed that on of the follwers hasnt been spinning at all cos theres no pattern on it and another one has been spinning then stopped and has two warn marks the whole kit only done about 50 miles, now would it be a faulty cam kit or my engine.

cheers
