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.

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.
