just finish restoring a 89 lt250r looks sexy but the bike ran when i got it and still runs went to put all fresh fluid in this thing after i started it the coolent starting pissing out and was getting exaust from the radiator i bought a top end rebuild kit im thinking i might have a head gasket or base gasket leak anywere else i might be leaking exaust into the radiator?

 

Sounds like a headgasket to me.

 

or how bout a leaking water pump prop seal letting pressure into the radiator notice when i polished the water pump cover there was a resadue on the prop kinda oilly?

 

Don't know about lt's but on Hondas when you get fluid in the water it's from something called a mechanical seal in the waterpump.

 

Did you replace the "o"ring between the two engine halfs. On mine 86 quad mine had a "o" ring between the two halfs.
