Thanks for the responses, some interesting comments here, but I would expect nothing less from this group !!
Oil level is normal, can't be sure of the smell. I'm going to warm it up & change it. I,m running larger than normal big end side clearances, so that is probably where some of the
oil pressure is going, and no
oil restrictors to the rockers. Just changed out the jetting as per jim inglese, so will have some tuning to do.
