I've just noticed something odd with the inlet cam on my YZF this evening - and wondering if it's normal? I had some oversize valves installed a couple of weeks ago, and after checking the valve clearances tonight noticed that the inlet cam wasn't turning as smoothly as the exhaust. With the camchain off and the cam cap torqued down, there's definately more resistance and a slightly uneven feel compared to the exhaust cam (which turns smoothly & freely until the lobes touch the buckets). It seemed to be running fine at the weekend, so it's possible that it's always been this way & I've just not noticed before, but I'm a bit worried about just slapping it back together. Wondering if something may have warped slightly so that it's binding? Don't know if it's significant but he valve clearances were very tight from one side of the head. JonE.
