Well, I have just done 50 miles and when I got back the engine was completely dry, so it looks very much like the PVR being only finger tight was the culprit. Like I said in an earlier post I don't know how or why it came to be like that. Hopefully the two new fibre washers and thread sealant have resolved the problem. I must say that I am rather glad that I did not go at it like a bull in a china shop ripping off the timing cover gaskets. Sod's law being what it is I could well have created a problem where there was no problem! Obviously the oil had been blowing back and lead me to a false assumption. Richard, I did not put anything in place as you suggested while I was out riding, but I have done so now in order to highlight any drips that might appear while the bike is standing over night. It is still a darn good idea though. Just one problem while I was out. Approaching the traffic lights the engine stalled. Can you guess what I am going to say? Of course you can. Would it re-start? no way!!! Anyway I did eventually get restarted (why do they do that I wonder?) and I stopped a couple of times to check out the starting. Needless to say it had reverted back to being a first kick starter. Lord only knows what the problem was, anyone got any suggestions? Oh the joys of motorcycling.
