The bottom end of the rod didn’t seem like it was blue. But I’ll let you know for sure when I have the case halves split. It could just be that it’s blue only right around the bearing and I’m not seeing it. I’m leaning towards thinking that the crank was poorly rebuilt. I was trying to save money, as I’m on a budget that should not be in karting but I love it too much to stop. I had a “guy” from a motorcycle shop rebuild it. I’ll never ever do that again. I was just under the impression that if you have the tooling to separate the crank and rebuild it, it must be fairly universal in method. Please don’t crucify me for that choice, I’ve already paid the price.
