BS..... Are you a dealer or are you just brainwashed. I suppose you use high dollar "motorcycle oil" Harley tries to scare the uneducated rider into buying their parts. Add what you want your waranty is fine. As lon g as you change the air fuel ratio by jetting properly you will not have a problem. Guess what, you don't have to use Harley oil either Castrol GTX works fine for $2.19 per quart, compare that to Harley oil!! Things that void your waranty are no oil, loose parts in engine, eg dropping a nut in the crank case and running the bike anyway, ALL COMMON SENSE.

TAKE YOUR TIME AND YOU CAN DO ALL YOUR WORK YOURSELF. If you are not confident or don't have time, I can do anything in my shop for half as much as a dealership charges, all flat rate no hourly charges

1000 mile service $50 plus parts and oil, you can bring in what you want in YOUR bike
