antifreeze coming out of exhaust

Postby j.maclean » Fri Aug 20, 2010 9:14 am



Hey everyone. I started my bike this morning (which was very hard to get started) when it did finally catch I had a little bit of antifreeze come out where the exhaust pipe connects at the muffler. It wasn't a large amount but enough to wet the ground a little. What could be causing this?? Is this something I should be really worried about?? The bike has been getting hot recently, since it started happening I haven't really been driving the bike, just starting it up from time to time. I was suppose to flush the coolant and replace the thermostat last night but I am still waiting (over a week now) for my thermostat to arrire at my local Honda dealer. I ordered one from Carquest as a back up. Any ideas???

G-day Mate, Well my guess would be a bad head gasket. Antifreez in the exaust is not a good thing. I would pull the plugs and see if you can tell which clyinder is the beast. If it gets enough liquid in the clyinder you could get a hydrostatic lock and bend a connecting rod, when trying to start. The leaking head gasket can also cause the over heating. I would check further before you do some major damage. Have you also checked for coolant in the engine oil?
Let us know what you find.

Enjoy the ride. They are all good, just some better than others.

Hey there, I just started working on it today..we changed the antifreeze and thermostat, filled the bike with water, let it run to get hot, it went to 6 bars and stayed there, the fan didn't kick in at that point and then we had to shut it off to go on a tow call, we are going to continue this evening, drain the water out and replace it with antifreeze (no silocate), then give it another try. When starting the bike today however..it was very hard to start so I pulled the plugs from the left side of the motor and they were both fowled with gas, now I had just replaced those same plugs about a month ago with the same issue, and they are fowled up again, lucky I had a spare set of plugs in the bike. The bike started no problem after changing the plugs. I wonder why the same plugs fowled up in such a short time? I haven't had the carbs syncronized since I bought the bike, and the bike sat for 2 years before I purchased it..maybe I should look into that next. I'll let you know how I get along with her.

Thanks!

It sounds like 2 cylinders are running very rich. If the bike sat for 2 years you could have a badly gummed up set of carbs and gumming usually causes the float valve not to work correctly in the float bowl, which leads to the float height being too high (float valve doesn't shut off due to gum/residue of old gas) and that causes the carburation to be very rich. It sounds like the carbs to those 2 cylinders need a good clean and degum!! If you do those 2 I would suggest doing the other 2 just to be sure..

If you do 2, do all 4. No sence in doing the job half way! You may not have a problem in the other 2 yet, but odd's are you will sooner or later. Look on EBay for the carb kit's. It's cheaper than buying them from Honda.


How many times do I have to tell ya,,, The right tool for the right job!
