water in cylinder

[multisat]

:( bought a 2002 derbi gp1 off of ebay full race mods 65mph or better runs great. rode a half tank of gas around the neighborhood checked coolent was low, filled it up ran about 10 miles was smoother and a little less noiser. parked it over night went to ride some more today motor was locked up. pulled plug cylinder was full of coolent . blew it out dried plug fired right up runs good. any thoughts on what is going on? cracked head, blowen head gasket? HELP PLEASE.

Your head is probably sealed with an O-ring and that has probably dried up some and torn. I would drain all the fluid then pull the waterjacket head off and check.

hopefully its not a motor from europe bc you'll be spending a ton of money on a 3$ gasket bc of shipping.

Yea, and with the extra shipping, why not just get a new Yasuni pipe. lol
