back fire

[v twin]

hi, i just got myself a 1997 firestorm and love it to bits, only problem i have with it is it keeps back fireing, i asked my local honda dealer they told me to higher the revs, i put it up to 1300 revs, it cured it a but not completly, if anyone has any ideas would be good, thanks guys

could be a bit lean, try opening the air screws 1/4 of a turn.

which cylinder, you can normal tell when it's the front cos it's a loud pop where as rear is muffled cos it's under ya ass.

mine was like that at about 3000 revs when i bought it i had it set up on a dyno it was a totally different bike when i got it back so much easier to ride around town etc (and i got a pretty print out of the power curve)
