once and a while i will be riding on my blaster and it revs really high all of a sudden whats that mean

 

My neighbors did that, If memory serves correctly something is caught in your floats. Take your carb apart and see if something looks bent.

 

Or it could mean you accidently hit neutral instead of second! lol

 

opps double post

 

The same thing happens to me when I'm nowhere near 2nd. I know for a fact it is my clutch from all the tight trail woods riding. I'm putting in a new clutch next weekend, so everything should be fine. anyway, check your clutch.

 

It would only be the clucth if it was revving real high and not going anywhere. I think his problem is an airleak or throttle cable/carb problems.

 

My blaster did that to at the race saterday. Comes up that its sucking in air check you airbox and carb bots for cracks if not try to adjust your idle under the seat will check back Bet that what it is greg

 

My blaster used to do the same thing, it turns out the carb flange i think it is? [connects carb to cylinder] was cracked sucking in air, if not fixed it can seize your motor up in no time. a new one is $35 from your Yamaha dealer and its pretty easy to install, loosen the clamps that hold the carb in, take carb off or slide it out of the way, then unbolt the 4 bolts that hold the carb flange on.
