Okay, that's a ways away for warranty work then. I'll bet the local stealers probably will tell you they won't honor the warranty, even if you have them do the mods. And the hidden reason will be because you didn't buy the bike from them.

I guess I have been really lucky on the last 3 Screaming Eagles that I have purchased as No Warranty issues have came up that would involve a dealer even contemplating if he was going to do a warranty or not. My 2006 SEUC will be going in for Heated Grip warranty but if a dealer had the gonads to turn that down because I have a different exhaust or cams, oh well he ain't the right dealer to be doing business with. I know and understand that the 07 Screaming Eagles are having some issues with the motor running warmer than it should so I guess what I am writing may not even pertain to 07 owners, I feel for you guys.
I use to take out the extended warranties and I just find it a waste of money:
1) I never keep a scooter longer than 3 years
2) I always make all types of mods - exhaust, cams etc
3) No major failures in last 6 years - really no claims after the 2 year standard warranty again on average keep the scoot for maybe 3 years
4) I don't buy insurance at the black jack table (suckers bet)
Different strokes for different folks but sometimes guys get caught up in riding a stock Harley for all the reason of a warranty that probably will never be used in the first place. If you buy the 7 year Extended warranty that's over $1k in insurance in my mind. For the $1k I would rather make mods and take my chances that I will not have issues and if I do, I hope my dealer helps me or I guess I fund the repair myself. Again in the past actually the last 4 scoots I have owned only had 1 somewhat big warranty issue 2000 RKC cam bearings and the MoCo even took care of it after 1 year warranty was up.
I realize the 110" guys have some additional worries, so maybe my thought process won't work for all of us - Good Luck Guys
