heres the deal; last year I had my 450 jetted about perfect then in between seasons it sat for a while now when I ride it it pops and backfires real bad when I let off after hard acceleration.
what is the cause I think it is the jetting, is it too rich, too lean? I looked at the plug and it looked fine. some one please help.
