Couldn't understand why bike was running hoptter than normal, pulled over and low on coolant. Wasn't far from home, so no problems, went straigh there. When I got home I looked around for leak and found sidestand and electrical plugs below waterpump were covered in coolant. Seems to be weeping from the bottom of the waterpump housing. Can anyone tell me if it is a gasket between the housing and the block or an o ring. I nipped up the bolts I could get to (how you do the rh one that's facing the block is beyond me!) - they were tight, but did move them a bit more. Haven't road tested yet, just wanted to see if anyone has come across this before?
