I am puting a new cam, rockers and oil pump in my bike (see post below) I picked up the Honda synthetic without moly and want to know if anyone is using cam lube when asembling the top end. It seams most cam lube has moly and I understand you do not want to use moly with a wet clutch. The Honda factory manual says to just lube with motor oil. This is the second cam and do not want to take any chances. Thanks "I picked up a '99 XR 650 L with 2,500 miles this summer and after riding another 1,000 miles I had the same problem. I changed the oil and filter when I got it and all was good. At 3,700 miles I replaced the cam, all four rockers and bearings. I also changed the oil, flushed downtube and crankcase with oil and checked the screen on the down tube. $280.00 latter was on the road. After 300 miles the same thing occured. After replacing the cam etc. I ran the bike with the valve adjuster caps off and it looked like it was getting plenty of oil"
