Time to take the Kawi out for a run, so, because of the overheating I experienced I presume water is not circulating through the engine?
1. Back-washed engine;
2. Checked the impeller for debris, none;
3, Blew air through hose going to pump, all clear;
4. Pulled exhaust pipe extension chamber muffler, blew air through brass fitting;
5. Removed exhaust pipe elbow,
6. Removed exhaust manifold, cleaned ports.
Reassembled and took to a nearby lake and engine overheated within minutes just like before. Of course, when the engine overheats, the engine goes into safe mode so can't accelerate.
Returned home and repeated the above process, but this time....
a. I removed the head cover and when I blew through the engine ports at least a couple tablespoons of wet sand blew out of the ports;
b. So, I removed the engine cooling cover and saw a build up of sand inside so I cleaned the cover and the two brass fittings.
I was told by an unreliable source that there are a couple holes behind the cooling cover that let water into the engine, but I see none.
Before I re-assemble, did I do everything possible to solve the the problem?
