QT50 60cc keeps seizing.

Justin Cabral /

got an 86 qt50. after cleaning the exhaust and giving it a tune up it ran mint.

shortly after i installed a 60cc kit with the stock head, bike soft seized twice. no matter how rich i tried it always kept getting hot.

my current setup is yt60 jug

qt50 head

ngk bp7hs plug

pw80 carb (jetted rich)

and a pocket bike muffler welded to stock header.

bike runs pretty good.

occasionally will bog at wot because its rich

but after about a 8 mile ride today it soft seized again on my way home.

any thoughts?

im running one base and 2 head gaskets

i was considering picking up a 70cc high compression head off treats but dont know if that will help my cooling issue

any help is appreciated.
