Need some advice and help

[RNL]

Hey everyone, last month I bought a 2012 YFZ450. I have rode it a few times, but today I got it out, and after I let it warm up for 5 minutes it bogs and sputters when I hit the gas. Also I'm noticing a slight pop when I let off the gas, and turn it off. Also it dies sometimes when I pull in the clutch. Any ideas whats up? Its about 42 degress out if tht has anything to do with it.

I did some searching and it sounds like all YFZ's come lean from the factory. Bad thing is, with this new carb, I cant find any info or advice on the 2012 YFZ.

I would take it to the dealership where you bought it from and let them deal with it, seeing as it should still be covered by the warranty.
