Yamaha 944 Union Bay/Fastrax Billet Big Bore and Jaws pipes

[TRIPLESWILLNEVERDIE!]

I've got a Billet 944 kit with fresh 2nd over bore and new pistons. Wasn't blown up. Just worn beyond spec. Fits Yamaha Red head triples. Will require upper cranckcase porting to fit on your bottom end. Comes with Jaws pipes. $1700 or may sell minus pipes for less. 406-293-2958 or PM me.

Union Bay 944

hay how much hp are you getting out of the motor? And is the 944 just as reliable as the stock triples? thanks

 

[TRIPLESWILLNEVERDIE!]

180 to 200+ hp depending on choice of carbs, pipes and compression ratio.
Nothing is as reliable as the stock engine but yes these are very reliable and will outlast the twin cylinder big bores on reliability for sure.
These engines use cast sleeves with Nick's Pro-X pistons originally designed for Sea-Doo watercraft and the sleeves can be overbored 4 sizes.

I see you have a price motor running bender pipes, how well do those work with the motor? Did you run this motor? Who originally ported it? Thanks.
