I recently bought a 1980 Honda CB900, and it’s having trouble staying at idle. It’s also started leaking oil. The previous owner said the engine was rebuilt, but I’m not sure how reliable that claim is. The leak seems to be coming from the front of the bike near the radiator area. The throttle also sticks while riding, and I think it may need to be replaced. I’ve noticed some sealant near the fuel petcock as well. I wasn’t sure if it might have gotten into the carburetors, but a neighbor mentioned it looks more like carbon buildup. I’m trying to figure out what could be causing the leak and what a reasonable repair cost might be depending on the issue. Any advice would be appreciated. I’m located in Las Vegas, and if anyone knows a fair and trustworthy mechanic, I’d appreciate recommendations.
