01 4v 300ex got it a few months ago for my girlfriend, and to use a mule from time to time with chores. got it cheap because it had a pretty good rattle from the top end (almost so loud it sounded like bottom end) looks like someone did a top end on it, and didn't know what they were doing. cam gear was ready to fall off, rockers over adjusted, bolts snapped, head bolts over tightened, yeah it was a mess! anyways thinking the cam looks good, but the cam bearings do not, and were loose on the cam, thinking about the hotcams cam with bearings. but I have a feeling its going to trade bottom end oomph for top end power.. anyone have any thoughts on this?
