I know a stocker superjet 650 makes 50hp. But what is the ballpark horsepower with a full pipe? I've looked around and cant find any numbers. If it helps my ski has a full pro tec pipe. Thanks

when i bought out coffmans, i got all their dyno test results for their pipes. bone stock 50.4 @ 6000. with their sizzler, a whopping 56.4 @ 6000. the #s go down as the rpm goes up or down. no pipe is going to get those #s any higher. tiny ports are the reason the 650 motors suck.

That is pretty disappointing. Thanks

60hp @ 6250rpm to 80HP @ 6750rpm on the 61X motors with the coffmans rocket pipe. 20hp and 500 rpm gain.
Wow, do you have any dyno results with other pipes and motor configs, or know where I could find them? I am just curious, these little two strokes are impressive.

Can you post the dyno results please? I am getting my 650 dialed in and would appreciate some jetting help if possible if you have all the Coffman sheets. And water routing
A stock 61x cyl is good for 60HP with a stock pipe and in the low 70s with a typical wet pipe. In 1996 they added a carb and changed the HP claims to keep up with Kawasaki. Somehow the 95 blaster went just as fast as the 96 with 10 less HP. A coffman Sizzler made a noticeable improvement on a 650 cyl and is even better on a 701 cyl.
