Hi guys
Finished off a rebuild last year, but I noticed that when the bike is left for some time then there is coolant weeping out through one of the main head bolts on the right hand side. When the engine is started and warmed up, it is fine the leak stops. Any quick fixes? Bodge jobs ? as I don't want to strip it down when the summer is here, i want to ride it . I suspect it is one of the o rings not sealing correctly.

Try re-torquing the head down.

Swap it for a 550. they're air cooled and tend not to leak coolant.

Re: Water leak through head bolts
Which one? The usual place to leak is from the stud which on some castings is open to the water passage.
If the head is correctly torqued down already, the head should be removed and gasket replaced. It's a fairly quick and easy job. No need to remove the motor to do that.

Did you put radiator seal in always best too.
