greetings ! new member here .........


1. important question:


are the gs 850 & the raptor petcock sizes the same ?


what I mean is ..... will the raptor petcock bolt up to my gs 850 tank ?


I need to be rid of the vacuum style petcock & the 2003 660 raptor petcock is the one I should use.........


but I`m not sure if the bolt holes are the same or not ?
this is very important .


I may have to go to Yamaha to find this out

 

The rebuild kits for the vacuum operated pet ***** are very inexpensive. There are a number of after market suppliers.

 

sounds like air cleaner could be clogged, causing an off ratio, (rich) condition. Fuel levels could be too high in carb float bowls. Did floats get saturated and sink? This is a less likely scenario because that sort of thing does not usually happen the same way to all cylinders.
