I just purchased a 2002 Wr426F. I have read all the reviews, and everyone tells something a little different. Do I remove the entire airbox lid, or just the snorkle? Do I cut down the throttle stop 7mm or 10mm? How is the stock air filter, what is a good recommendation, K&N or UNI? I have removed the baffle from the exhaust, but eventually want to replace it? I am considering a Hot Start Relocation Kit for it, I know the pros, but are there any cons? Thanks!
