I just bought a kawasaki 550sx 94 or 95 reed valve stand up. it has nearly every aftermarket part and mod you can do to it. 44mm single carb, shaved head, exhaust, scoop grate, stainless prop, ride plate etc.
anyways its having a problem where its difficult to start and floods easily, the battery isn't charging after a half hour ride and it is extreemly under powered. have been through 3 sets of new plugs, it has new leads,spark seemed fine, emptied the tank, cleaned the pick up and put in fresh fuel with 45:1. I have also had the carby off and cleaned it.
Still wouldn't go so i took it to a jet ski mechanic. they did a compression test, checked the spark timing, tried hotter plugs, however they think it may have week spark. i dont think they have worked on these before (being that old) and just couldnt pin point the real problem.
anyways they could get it running (still hard to start and fueling up plugs) and it seemed to rev freely. i took it down for a test and its exactly the same. hard to start, under powered and not charging the battery.
to me it sounds like something in the electrical system is not working correctly, giving it weak spark, poor performance and hard starting. i just wondered if anyone has had a similar problem before and had any ideas?
also what should i replace first?
