Sean, I have been to Barnwell many times. 'course not on a MB! Since my motor has no specs or tags anywhere, I don't plan on putting anything about what size it is. No need to call attention to anything that isn't there already. I just got back from an 18 mile shakedown trip. (and with these hilly country roads, I mean "SHAKEDOWN"!)
So far, everything is OK. I even managed to get back before the thunderstorms rolled in. Good luck down in Barnwell, it is about 94F here today, so it is probably even hotter in Barnwell.
