Definitely not the clutch pushrod - that was the first place I looked! I have done all the usual troubleshooting stuff involving talcum powder etc - no signs from cylinder base/head, oil pressure switch, oil filter, oil cooler hose joints etc etc - I am 99% sure it's coming from the casing itself! Hopefully will get a spin on the bike this weekend to see if my temporary repair has plugged it up (I have used some Oilite Stick - it's stuff we use in the airline business to plug up running fuel leaks on our Jumbo's...). Does anybody know if the clutch cases on 2 and 4 valve motors are the same? RX |
