Anti freeze leak !

Post by squirrel »



After the bike has been sitting for 1-2 days there are 2 small pools of anti freeze /rad fluid right under the engine on either side (under plugs) could this be head gasket or water pump . Gl11 00 82 ...could this also be a symptom of losing power under load .thanks

Not water pump that's a weep hole up front on the 2/4 side. But you may have a leak from the water tubes on top of the engine that are leaking down into the weep holes in the head..and dripping out the bottom of the head. especially if the bike is on the center stand and level??? Or yes could be a head gasket issue but both side at the same time ...??? very usually unless you over heated the engine..low oil or low water???

Thank you ,I'm thinking along the same lines .it looks like I have 2 issues ..1, missing under load at 3000-4000 rpm.(tickover is good )plugs/leads/coils / igniters all changed no difference . And the antifreeze issue ?

check YOUR BATTERY FOR GOOD CHARGE UNDER LOAD..WEAK BATTERER OR charging system/wiring could cause the miss..

Leaky head gaskets usually leak between the coolant passages and the cylinders, never seen one leak external. I'd go with cooling tube o-rings.

Little 1 inch dia tubes that run from the top of both heads to under the carburetors, they are the return path for coolant from the heads back to the radiator. There's o-rings on each end of them where they press into the fittings.

First you want to drain down your coolant so you don't have a flood....

You have to remove the little elbow on top of the heads where the tubes go (two little bolts). Be sure you have your new o-rings and new gaskets for the two elbows first. Once the elbows are loose, it all just pulls apart. There's o-rings on both ends of the tubes, so you will need four of them. A little grease on the o-rings helps everything slide back together.

Pretty simple, really. The hardest part is scraping off the old gasket from the elbows and heads.
