Recently bought a 1989 kawasaki 650 sx (and someone else's problems) haha
took it out a few weeks ago and it ran great, it sat around for a few weeks and on my next time going out riding it didnt go so well
jet ski would start but would not go over 5 miles an hour at full throttle, eventually died for good and ended up swimming back to shore
ive been told it could need a new starter, new crankshaft, ground wire done a different way, or an exhaust leak.
anyone have any ideas of what could be wrong with it?
