Yesterday I rode my m600 2001 for 2 hours.then took a gas from gas station out of the town.After that bike started poping,especially When I was off the throttle while down shifting.Today I changed a gas with new one-still poping.I checked carburator if I didn't lose mixture screw or something,checked spark plugs-o.k.so if anybody knows what can be cause please some advice.

once again I checked everything and I can say there is backfire while deaccelleration.any idea?

Is your bike running normally otherwise?

Idle speed and quality are OK?

Do you have the stock exhaust on the bike? If it's aftermarket you could have a small exhaust leak where the slip-ons..er...slip on.

Even if you have the stock cans, make sure they are seated and tightened down.

yes,bike's running o.k.idle speed is o.k too.I already checked for air leaking.I have got stock exhaust-o.k.does anybody know what mixture adjusting is for m600 2001?I have 3 turns out.

since it happened right after refueling, why not drain float bowls and see what comes out. drain into a clear container and if there is water it will be on the bottom.

My 2001 m600 mixture screws are turned out 4 turns. I also put in some hotter plugs NGK DR8EAs I think and that relieved my popping problem.
