I have a 98 ZXi 1100 that is completely stock and has a top speed of only 48 MPH verified by GPS! Here is the history of the ski:
I bought it from a friend of mine who submarined it in salt water on the last ride of 2003. Thinking nothing of it he towed it to shore put it on the trailer and let it sit that way for 5 months! Needless to say the engine was destroyed including the carbs.
I bought it and installed an SBT engine and a set of used CV carbs from a 2000 ZXi 1100. I ran it enough last year to get through the break in period (3-1/2 tanks) and that was it. I never held it open too long last year so I thought nothing of the top speed until this year plus I did not trust the onboard speedo.
The engine seems to be fine. It starts good, idles in and out of the water, has a hesitation when punching the throttle from idle but this seems to be a notorious problem with these CV type carbs. After the hesitation it will shoot right up to 7000 RPM and stay there. There is no cavitation that I can hear and compression on cylinders 1, 2 & 3 is 105, 105, 107, respectively using a new Sears Craftsman compression gauge with the proper adapter. According to Kawasaki specs compression should be 136 PSIG. Could this be the problem?
Where else do I begin to look? Is the max RPM correct? Also, what the hell is the official top speed for these things (stock form)? I have seen everything from 57 MPH to 68 MPH! I suspect its closer to 57 MPH.
PS I am a 190 lb rider.
Thanks
