The fan and sensor seem to work. I did over fill it now that you mention it. Looked like the coolant was coming out the spark plug threads??????????? you think it was coming from above?

I just cleared up a very similair problem today. Gas cap.

Hi guys, I recently picked up a used Techno 250 (1997). I ran for a few hours last month and at the end of the ride I heard gurgeling in the coolant system. Check the fan and it was working. I topped off the coolant and rode today for about an hour and I saw smoke and smelled antifreeze. Upon inspection it appeared the coolant was coming out the threads of the spark plug and head cover. Any advise is greatly appreciated for I do not know much about these 2 stroke engines! Thanks.

Just to say Hello and thanks for having me!
