I put some SuperTech 20w50 conventional oil in yesterday, along with the 140 jets to replace the 145's that were in there from the previous owner. It seems to run stronger, probably more due to the jets than the oil. I'm starting to get just a little popping under deceleration if I cut the throttle with the revs high, but no pinging under load. Hopefully the rings will still seat okay and things will keep improving. I will say that riding in a hot climate is borderline painful on my feet due to the heat coming off the heads and the exhaust. I think I'm going to wrap the headers, just for my own comfort. Don't worry, the headers are already pitted and in need of replacement, so I'm not risking destroying anything irreplaceable. Is there anything else I can be doing to minimise the heat on my feet?
