    Super Jet Speedwerx Dry pipe on 62T 760?

    Looking for any input regarding putting a speedwerx dry pipe on a 62T 760 in an 08 style superjet. The pipe was previously used on a 61x big bore cylinder. I'm assuming just drill out the bolt holes for the larger bolts? Do the exhaust and cooling passages on the manifold and cylinder line up...

    Other Two stroke at 200:1 mix ratio.

    Cool Article I found. I like the part where the EPA is conducting their own study regarding the elimination of particulates. Maybe there is some hope for the two stroke without using complicated DI or EFI. http://twostrokemotocross.com/2010/06/can-a-two-stroke-run-at-2001-fueloil-mixture/

    Help me find my superjet's 500 missing RPM

    I recently purchased a PET tach, so I could make sure my SJ is tuned properly before dumping more money into the motor. But after several smooth water peak RPM tests, I saw I was only hitting 6450 rpm. That's about 400-500 shy of where I should be. Dave/Impros said I should be about 7000 give...

Seems like mine is hotter than it should be. How hot should a waterbox be; cool, warm, hot to touch, too hot to hold...

    5200 didn't stick to my footholds

    A couple years ago when I installed my footholds, I used 5200. I sanded and wiped with acetone both the footholds and painted surface of my ski. When I removed the footholds to inspect some hull damage, I found that the 5200 didn't stick at all to my holds and had been letting in a little bit of...

    Why is my FX1 so loud?

    I put a mod bpipe on my FX1 recently, and just took it out to the lake last weekend. The rest of the motor is stock. It was way, way louder than my RN with limited pipe. Same cooling line routing. I reconfigured the stinger and bypass lines at the tee for more water to the waterbox, but with no...
