I had to go up to American Eagle Harley-Davidson to pick up a 180 main jet today. The 175 just wasn’t cutting it, pinging all over the place, running really hot, and fuel mileage in the mid 50’s. I’m not going to trash my new engine running like this, so it got swapped. It looks like the 180 main/45 slow plus 93 octane’s cured the problems. It’s still running a little warm so I’m going to put on an oil cooler at some point.
