2 Stroke Powerband

It may be underpropped too. The strong mid hit of porting for racing is intended to help pull a taller prop/impeller/swirly thing lol

the light switch power is due to the porting, period. it wasn't built to be ridden like a baby carriage. let the squids and flounders ride the turds, unless you want on the turds too lol

I was hoping you might stumble across this and chime in, thanks for the input buzz.

I like to try to limit my ski count to two - it's currently a superjet and SXR. If none of my squid and flounder friends want to ride the kawi, I'm just stuck on it all weekend. I'm not complaining, well, maybe a little bit. I do miss the superjet, barely rode her this year.

I agree with Buzz, I bet Vforce tells you to put a stock cylinder on it, pretty much what your asking for.
 
Props to all you smart people with friends!!!

Send me some pics of said ported cylinder that hits like a fat girl at a buffet. I may be willing to take it off your hands. (I'm a team player, ya see)

Asking the obvious question. Have you played with the Factory Wet Pipe Head Pipe Screws? (which are a joke, 3/8" nut with a 2.5mm allen?!@!@)

I just installed a Wet pipe on my SXR, and the light switch effect was from not enough water in my scenario.

If this engine is ported like it is, the pipe should still be able to soften the "hit".

Is there any way to smooth out the power delivery? The powerband hits hard around 1/4 throttle

There are several ways to shift the power band but you might start loosing efficiency especially if its a porting issue, cant get something from nothing

Try drying the pipe out as much as you can without letting the couplers melt, this should help shift the power band later. This is the easyest thing to try but might not get you to where you want to be unless the pipe now is flooded with water.

You can also add a couple degrees to the impeller so it takes more RPM to hook up
 
Again, why are you trying to modify YOUR SKI because your friends can't handle the hit?

If you want to mellow it out I can totally understand but like I said if they don't like it then they can find another ski to ride for free.

If it is a ported cylinder that is probably a big part of the problem as porting moves and can make the "hit" worse. On as stock ski it is made to be mellow for the general public. On a race ski its in the upper rpm range where they typically run and on a freestyle/surf ski it is down low, generally speaking.

Most of us on here have friends with ski's. Some of us don't, and those friends that don't also don't have the money to buy said ski's for them. Really not the difficult concept some are making it out to be.
