bike was pissing oil out when I bought it from under the tacho drive where it had burst through the head due no doubt to some ham fisted arse not ensuring tacho gear was engaged properly with cam gear before tightening cam down!
been a right ballache with a mix of welding, putty and epoxy resin but think it should be ok now..........time will tell!
this photo was before dressing area up with porting tools
