I have the 2006 WR450 with the stock jets in it as listed here: Main Jet = 165 Pilot Jet = 45 Pilot Air Jet = 80 Starter Jet = 65 Leak Jet = 50 I went for a ride this past weekend and she did not want to start. The bike had been in the back of the truck enduring the cold rain for 3 hours previous to the ride. I had to bump start it to get it going. So far, I have installed the TT AIS kit, PMB exhaust insert and removed the snorkel. It is still backfiring and popping like crazy. What should I do to help resolve the issues?
