I have had similar experiences in the short months I've had mine...specifically, my bike is returned with more problems than it started with. I have become a total believer in this forum. Everything you need done to your bike - including diagnosis - can be be started here. I'm not not a "stealer"
basher really, but I've learned the hard way (scratched pipes and rear fender) that even a simple oil is a big risk. Fact is, I've bought a couple bikes now from this same stealer, and have become somewhat friends with the salesman. He actually came to my house yesterday to remove a rusted trailer ball from his hitch, b/c the shop guys at the stealership couldn't do it. I had it off in about 30 seconds.
Bottom line, use and trust the 4M. I do it all myself now, inlcuding all the basic mods.
