Probably isn't a back fire. It may actually be the engines exploding on the PW-70's that you are drag racing.

How do you do that? Do you have to take the carbuerator out? Do you have to buy a jet kit? :cry:

IF it's just your muffler backfiring you should take that one off right away,it's probably gone bad.Put on a different one and keep drag racing any quad you come across. Now if you remove the carb, I definitly recommend installing a jet in it's place. LMFAO :cry: :cry:

Do you think I am stupid? It's probably the engine making it backfire. You Canadians!

It wasnt backfire, it was a pot shot from a disgruntled TT'r who has to read your post here. :cry:

Main jet is easiest to get to, just take off your float bown (bottom bit of the carb) and its screwed in the bottom. You can loosen the carb and twist it round to get access to the screws.
NEEDLE IS MORE TRICKY, LOOK AT THE MANUAL!
