Hi im hoping someone can help, i have a 2002/3 yamaha viper sx and it wont idle. i have set the 3 piot screws to the factory settings which is 1 7/8 turns from the seated postion. it will idle however with the choke out in the mid posistion, but i burn through the fuel obviously. sled season is here so i would appriciate any ideas.
hey thanks for the reply. Im not mechanically minded at all but i actually took the carbs out and all three pilot jets were blocked. i cleared them out of course and every think else looked good. It took a few pulls to get it going again but i got it started. After about 1 minute with the choke half on i turned it off and it Idled perfectly, then adjusted the idle speed and it seems to run better than it has done since i bought it.
