just got back from vacation. didn't get to ride a lot, we got caught in the storm that hit the NE. Anyway, as I pulled into the auto train depot in lorton virginia last night, I noticed my engine was tapping loudly. Don't know what valves sound like but this was a very distinct tapping that was present at idle and appeared throughout the RPM range. I was literally loading the bike at the time and did not have time to explore the problem. I did not check the oil pressure. This morning after the bike was unloaded, I checked the oil level, it was right on the money for a cold check. Fired the bike up and there was no tapping but the oil pressure was now reading high. I'd say it was between the 30 and the 60 on the oil pressure gauge at throttle and at idle it would settle down to about normal (32). It stayed that way for about 20 minutes and then began functioning properly. I believe the train car was air conditioned because both my bike and Richards was cold and had condensation on them. I have installed an ultra cool oil cooler about 1k ago but, other than that, the bike is stock with a stage 1. I've heard of certain bikes having issues with their cam shoes wearing and tearing up the oil pump....my bike is an 08 and has the automatic cam shoes so I am confused as to what could be going on. Is it possible something else could have jammed the plunger on the oil relief spring/?
