Is this a quad since you say YFZ?...or did you mean YZ/F..ill assume YZ/F.

Dude, find a new dealer, obviously your dealer knows nothing. either your jetting is off, or your valves need adjusted...also, if there was gas in the carb for awhile, it might be gummed up, so you might have to clean your jets...its not that hard man. but good luck.

My 06 YZ popped, blurbled, & liked to stall until I fattened up the pilot jet ( I think I installed a 48 ) & now it runs great!!

you need to rejet it.....it is way too lean and the air/fuel screw needs adjustment -

buy a 45 and 48 pilot jet and a 165,168,170 mainjet and a Adj fuel screw.....you will need to get smarter on jetting and adjusting the fuel screw in order to get your bike to run right.....do a search on both here for this forum

start with the 45pj and 168mj and just under 2 turns out on the fuel screw
