vacuum lines

[Miltofeburg]

Need assistance or a schematic for the vacuumlines to the carbs for a 2002 Yamaha Royal Star Venture.

 

Thanks...

Go to the 2nd Generation Tech library and then the guides and parts diagrams, and there you will find a downloadable copy of the factory service manual. I'm sure you will find the information you are looking for there...

There are only two vacuum lines on an RSV - one goes to the front AIS valve near the radiator, and one goes to the rear AIS valve below the right rear of the engine. these lines are very important, as the high vacuum shuts off the air induction into the headers when you close the throttle, thus eliminating popping and after-fire on deceleration.

 

You must make sure that these hoses are not cut or nicked at the intake nipple, as well as making sure the other two vacuum caps are soft and have NO age cracking when you bend them. It is common for ham-fisted mechanics to nick those lines with pliers when taking them off to sync the carbs, and the caps need to be replaced every 3 years or so due to heat and fuel contact aging.
