Here is the problem with old gasket, bike was overheating and spitting coolant out the breather hose of overflow tank.

Mine just blew the whole bottle and then some all over me and the whole right side of the bike yesterday. Will be tackling this job soon, just need to find gaskets 1st. It'll give me the opportunity to investigate the connecting rod big end bearings also, as I suspect they are failing.
