My motorcycle hasn't been run in about 7 days, and when I started it up today it...
 

...backfired while choked.. help Its about 50 degrees where its stored. Should I be worried that it backfired about 4 or 5 times while choked, and then warmed up fine once I backed the choke down and let it run? Its a 2000 Suzuki SV 650 S (v twin). Its never had any problems before, but I"ve also never let it sit for 7 days before between startings. Thanks for any help!!! Cheers.

this can happen when a plug gets wet from choking then fires all the raw gas in the muffler might want to put new plugs in might help
