Happy Monday everybody. I have gen 1 and its making quiet a bit of drive train noise. I had a valve adjustment about 10k miles ago and Im currently at 38,000 miles on the bike. I ride about 500 plus mile a week of mostly highway and do not race the bike. I am not sure if the cam tensioner has ever been replaced so with the being said... should I go with the stock or the APE manual one? What are the benefits of either one? Also where do you guys source your OEM parts from since the OEM one is about 110 dollars and the APE one is 52 dollars? Thanks everyone.
