Dear Kuttappan,
Been using my bull since college days. I never had the tick-tick (cam wheel) noise on it. But, last time I had the cam cover removed to check the oil pump I noticed that the two Cam Wheels weren't OE, instead they had eccentric spindles. Not only that the two other wheels, #1(idler) that drives the #2 timing gear. Both were made of Nylon

. Ever heard about those before? probably dad had them put in long back. because since I got the bike the cam cover was never opened.
Can you throw some light on these. Should I change them back to OE? As of now the gears look in good shape and the bike's performing ok too. Need advice.
