Ok so my zxi starts off for the first 5 or so min at a top rpm of 7200..then after that it is restricted to no more then 6k on nice calm water...then when i hit a no wake zone or idle for more the 5 min it seems to bog like crazy and wont go over 4k rpm,But if i keep it full loaded it will eventuly clear up and go back to the max of 6k...If I shut it off for about 20min it will start for the same routin..ill get thatn 7200k for a bit then right back to the max of 6k..Driving me crazy and I know it should be faster..im topped out at about 40mph..Should I rebuild the carbs??

 

I don't know a lot about these because I just bought mine 2 weeks ago, but I just got a 93 and 94 Super Sport Xi and the first time I took out the 94 it ran great for the first 5-10 min and then slowed down to 5500-6000 max rpms. The next few times I took it out it didn't get above 6000 rpm.


I knew it hadn't been run for a while so I decided to start simple. I threw some new plugs and stuck a half a can of seafoam in the gas tank and it runs great now.
