Leaking Coolant

My bike is leaking coolant from the overflow tube on the expansion tank. It is fine on short trips but anything over 10 or 12 miles it happens. I have flushed out the rad and put fresh coolant in but it still happens, anyone got a clue why this is ?

could be a blockage in the coolant system? any signs of the dreaded head gasket?

No not realy, there is no gunk in the oil and the bike doesn't get too hot

Not above the top line. I have just looked at the rad cap and there is a small split in the large seal, would that cause this prob?

certainly won't help. Swap that cap and see how it goes.

sorry to be the bringer of bad news .. and of course i may be wrong .. but if its blowing water out of the expansion tank on runs longer than 10-15 min and NOT overheating/running hot.. its quite possibly blown the head-gasket and is pressurising the cooling system.
