Hi all. I ve a little problem with the XTX. Its leaking a wee bit of coolant near the readiator. There's no obvious cracks in the expansion thingy or the radiator itself. The hoses are fine. Ive already replaced the radiator cap to no avail.

Its leaking a few drops every ride. More so when I hammer the bike (pressure related, Im sure). The drops accumulate at the bottom of the lowest hose where it enters the engine.

Is this a common fault on the XTX? Any suggestions as to what it might be? miniature crack invisible to the naked eye somewhere or something?
