A FARTING NOISE?

[350BANSHEE350]

i started up my shee today and let it warm up till the pipes were warm and i went to just drive it up my driveway and into my garage (20 feet to get it in)and half way there it made like a fluff pop fart kinda sound and so i went back down the driveway and it did it again

i didnt even put much work on th motor because i was using the clutch alot

i did turn the TORS screws up 1 turn, would i need to rejet for that?

it is only 2 degrees celcius outside and i can see my breath so im guessing thats the problem

BTW my bike is all stock the only thing i did was the TORS screw thing

 

just wanted to make sure that nothing is wrong with it before i take it out on may long weekend

 

thanks for any advice

wtf are tors screw. im guessing you mean the idle screws on the top of your carbs in the big ass tors unit. try a new set of plugs sometimes then foul out over time more so when you mix your gas with alittle extra oil. if new set of plugs dont work jetting could be the issue because of the cool weather. but ry some new plugs.

sneeze could be carbs out of sync or a little lean if it was jetted for summer
