It happened on my 03 RK. The bike was covered under the extended warranty, but they would not pay to have it tightened, per the new HD guidelines at the time. They said it was maintenance issue. I asked the dealer if any where in any of Harley, service manuels, does it call for checking the compensator nut.
Guess what the answer was. NO.
The extended warranty would not pay. I was told that I could argue with them, but I valued my time more. They charged me $30.
Good reason not to buy an extended warranty, I guess. I like I told a guy once who was trying to sell me an extended warranty, If I have to buy the warranty to feel good about my purchase, I guess I did not need his product.
