I picked up a used 2011 XR 2500 miles on it. The original owner told me he had the dealer "make the pipes loud" before ever picking it up. When I took the bike for a test ride it did sound great, but it backfired regulaly and popped constantly. I put a Llyods fuel Controller on it so I could add more fuel. Amazingly the bike would run best with the idle setting at its lowest (#1). whenever I tried to set the controller for more fuel the backfiring got worse.
Then the scariest thing happened. I was on the throttle quite spiritedly and came up on a nice right hand turn. I
ked the throttle off as a entered a right hand turn and the back tire locked up completely! I was thrown on to the handle bars as the bike started a full slide, handle bars pinned on the stop to the left. I quickly grabbed the clutch and rolled to a stop.
WHAT THE ________?!!!
Best I can figure is the motor backfired bad enough to stop the motor solid.
TIME TO SOLVE THE PROBLEM. I took the mufflers off and realized they had NO BAFFLES AT ALL ( no wonder it sounded so good).
I ordered a set of Bassani slip ons and thank God it solved the backfiring and popping problem.
The bike runs best with the Llyods idle setting at 2 or 2.5 which is still suprising but I am not sure what the Dealer did to the settings when he took the baffles out. I alway thought back firing was a sign the bike is too lean not too rich. Oh well it runs good now.
I am not Mr. safety but I wanted to put this on a forum to say, No baffles and a backfiring bike almost caused me to crash big time. Be careful folks, my Victory likes back pressure and with out it, it is dangerous to ride.
