My 06 450 has about 20 hours on rebuild. but recently will not start unless i pull it down the road. when i get it running it stays running but it does seem to backfire alot. THe weather has cooled off but didnt have this trouble last year. the bike will start when its warm

I would check your valves first, it's easy to do. Depending on what you find out there I would give the carb a good cleaning and recheck the jetting.

Check your pilot screw, if its turned in to far your bike will be a pain to start and will pop like crazy on decel. Is your bike Backfiring or popping? There may be an air leak in the exhaust if it wasnt installed correctly.
