Hey guys, I have an 02 SXR600 tripple. At the end of last season I put stabilizer in the tank and ran it for a few minutes to make sure it got into the carbs. I also fogged the engine. I went out the other day to start it up for the first time of the season. It had a little less than 1/4 of a tank of gas. It fired up in about 8 pulls. I shut it off and about a half hour later I went to start it again and as soon as I pulled it over it backfired then started. But this was no normal backfire! It was as loud as a gun shot. I called the dealer and explained the situation and they said it was normal because it had a lousy ignition due to me fogging the engine. Is this normal? Thanks for the help.
not normal, but not uncommon either. could have been left over fuel igniting inside the exhaust, poor quality fuel, or any number of fuel related issues, or the engine didnt come to temp on the first start up. dont worry about it unless it happens repeatedly. be sure and let the engine come to temp before shutting it down. you should be able to feel heat of the exhaust gasses coming out of the outlet through the bellypan.
