I just had a weird thing with my LT450r. THe damn thing wouldnt run and we thought it was the fuel pump, well our idiot local dealer,(pro-caliber in longview WA) said dirt had gotten into the motor and it needed a whole new top end(never had the head off by the way). Well i picked it up becuase it just had a high comp piston in it a few weeks ago, it turns out the fuel filter wa plugged, bad. When i went to order a new one the guy on the phone said they cant keep them in stock becuse the filter reacts bad with race fuel. Im blown away, does anybody have any advice or a similar prob?
