Best Carb/Pipe for 960ccm PV engine ???

[Kawastyler]

The name Frankenstein is a popular term for mismatched engine components such as a 61X case with a 760 cylinder on top. This looks like an inexpensive way to make a bigger displacement engine with power valves if it's not to much trouble with the machine work.

Is the base bolt pattern the same on the Sea-Doo cylinder and Kawi cases?

Did you happen to check the port timing on the engine you built?

The reason I ask is because if the Sea-Doo stock 951 engine uses 140mm length rods with a 78.2mm stroke you would think there wouldn't be any need for a spacer plate with 133mm Kawi rods and a 74mm or 76mm stroke?

Hallo 0#,
stock kawirods......cylinderhousing shortened arond the sleeves.
Basebold nearly the same,buy only nearly.
I screwed and glued the spacer with new treats on the case and bored seadootreads in the spacer.......will see how long it works

So basically WFO Speed Racer's idea of making a set of cases like Brian Reed is doing for the GP800 engine platform is a good idea. It would be nice to have a set of new cases where you can use the SD 951 top end gas valves and all. Problem is an exhaust manifold will be needed too.

I use the FP Bpipe manifold....is a 15mm spacer Seadoo to FP.
at moment it is a Pipe from a friend, if i have a new Pipe i mashine the bores to cylinder wider in the manifold to get an oval like seadoo.

brandon reed has also set up different cylinders to fit on his billet cases, several different polaris snowmobile cylinders fit on his gp800 crank and custom cases


This is quite the motor, Its a very interesting approach, I love it when people get creative. Good work
