Help my cr250 has coolant in the barrel????

Question

Hi, I am currently restoring a cr250, 1987, and had a problem with the radiator coolant, firstly whenever i filled the radiator up the coolant ran straight into the gearbox. I found a small hole in the gearbox cover by the water pump and filled it, so i thought i was ready to go. However, i filled the radiator with coolant, the radiator held the coolant fine, but when i kicked the bike over there was nothing. I took off the exhaust to take the head off and i noticed the exhaust was full of coolant. There is obviously coolant getting into the barrel and diluting the petrol. Does anyone have an ideas please???

Answer 1

head gasket

Answer 2

like the other 30 people before me said, head gasket

Answer 3

It is either a Head Gasket or a cracked Barrel Sleeve. I think these sleeve can be removed and a new one can be installed. Not a home project tho, unless you have an Oven and a Press. Indexing the new steel sleeve to the barrel is critical.

Answer 4

preasure test it....make up one using a foot pump tube and a old rad cap...drill the cap,tight fit the tube,fit other to the bike tyre/valve...pump up the system and listen for leaks ,...

Answer 5
