hey guys i have a 06 xb12s  and it has 6000 miles. when i got it had no muffler on it so i got a stock xb12 muffler of a wrecked 08 and got it put on. well before it was backfiring thru the airbox and i thought it was from no backpressure and its still doin it. its bone stock. ive put about 40 miles on since ive bought it. can somebody lead me in the right direction? thanks

i'm guessing there would be some interior changes to the muffler between the '06 and '08. i would also get the AF ratio checked.

I just had mine serviced a few days ago and it still does it.   I keep wanting to do the hose reroute to get rid of the gasses.  Thinking it could be crappy gas in my area not burning like it should.  And my the white wire but I can't find it.

just to let you know, that some puffing is normal, but it shouldn't be a frequent thing.

Same happens with me when clutch is fully disengaged and in neutral. Thats why I never rev in those situations . I think its the spark skip technology that causes this, to prevent excess unneeded heat.

Quote: well mine does it like when you try to rev when the clutch is in or in neutral It will do it more often when the bike is not at optimum operating temperature.  Its probably part of the emmissions control.  If you dont have to get your bike emmissions tested where you live, do the breather re-route, this should solve 99% of it

You are running premium right? You're engine will run like crap on anything else, also, you might have gotten a tank of bad gas, has this lasted for more than one fill-up? Try changing your gas station... The breather re-route will help with the surging from idle-3k that is common on all of our bikes.

Octane Booster is fine I use one that is good for up to 20 gallons at least every other tank. Just makes it stand up faster is all..
