99 ZXI 1100 overheating

[chris134]

I just installed a new sbt engine, pump and rebuilt the carbs on my 99 1100. Rode great for a few days, then started to shut down after a while. Restarted immediately and rode fine for a few minutes then shut again. I noticed the engine was hot and the pisser wasnt leaking on the side of the engine. Noticed the forward spark plug was grey (other 2 were fine), but pisser worked when hooked up to the hose on land. The top exhaust pipe was cool but rest of the engine was very hot. Could I have a cooling system blockage? WHat is the best way to test it and correct the problem? Ski was running perfect before this. Also, temp light never came on. Does the engine shut down automatically when the temp gets too hot??

Check the cooling line from the front cover to the exhaust if its clogged you will burn the front piston.

blew out entire cooling system with compressed air. Engine running fine and overflow line is flowing water, but the head feels very hot to the touch! What can be causing this??? Running about 40-1 premix and using NGK BR9es plugs. Could the water jacket in the head be defective?

I would not think so, how hot is the head getting?

I can only touch it for a second or 2. The exhause is cool to touch and the water out of the pisser is warm.
