loosing coolant rad overflow pipe

Recommended Posts

It does not normally loose water, so switching caps is not necessary, unless there is something abnormal going on.

My guess is that the gasket on the cap is dirty. Clean it with a brush under running water.

Also make sure the filler neck is perfectly round, it can become oval in crashes.

If this does not help, try a buddys cap. They fit from all bikes.

If that helps, buy a new cap!

How much coolant are we talking about?

Are the radiator flutes clean...can you see through the rads? Water pump maybe failing causing overheating. A leaking head gasket can cause combustion pressure forcing coolant out. Is th coolant discolored at all?

BTW these bikes were not made to sit idle for very long so keep the air circulating through the radiators or it will boil over pretty quickly.

its not long had a full engine rebuild so from wot u mentioned i wouldnt be surprised ifa head gasket is leaking now is that from incorrect torque setting or does it need stripping down and replacing

If the head gasket leaks that way, you should be able to see some bubbles and/or some oil discoloration in the coolant.
