Backfire after reving engine
Just bought a 2009 gz250 with only 320 miles on it. Engine would die with zero choke even when hot. I then adjusted the idle speed per owners/service manual and now getting small backfire after engine back down after reving. Any ideas on what to do.

Re: Backfire after reving engine
Go with what Blaine suggested. The carb is probably all munged up from stale gas and varnish from sitting so long. You should never need the choke except for cold starting and warm up of the bike.

Re: Backfire after reving engine
Or, look for an intake air leak. It could account for all your problems. (I suspect you actually have after fire, out the exhaust, not backfire, which would be back through the carb.) An exhaust leak can cause after fire, but wouldn't account for the idle issues.
