wesw Posted April 9, 2007 Report Share Posted April 9, 2007 if your getting gas to back wave thru the carb you most likely have reed problems. will it even idle?? Quote Link to comment Share on other sites More sharing options...
r/atvshee Posted April 9, 2007 Report Share Posted April 9, 2007 bad floats could be an issue too Quote Link to comment Share on other sites More sharing options...
J-WELDO Posted April 9, 2007 Author Report Share Posted April 9, 2007 if your getting gas to back wave thru the carb you most likely have reed problems. will it even idle?? Yes on one cylinder but when I rev it up the other cylinder starts firing but when I let it come back to idle the other cylinder dead again Quote Link to comment Share on other sites More sharing options...
wesw Posted April 9, 2007 Report Share Posted April 9, 2007 are your carbs synced at all. all i know if your getting gas to shoot back thru the carb you have issues. rn brads bike was that way at the dunes wouldnt idle ran like ass. i think he is getting new reeds. i had some vf2 go bad wouldnt idle it would idle high the fall on its ass. motor ran like barely on one jug. i would start that. pull the reeds off and you should see any light. the pedals should be closed completely.

ALTVATER Posted April 9, 2007 Report Share Posted April 9, 2007 my 421 did that this weekend also i just took my carbs apart and cleaned the hell out of the floats. i think my oil in my tank settled b/c my floats were covered in oil. just an idea i don't know if it will help u and u might have already went through ur carbs. but after i did that it fired up and ran great.
