Stupid fuel leaks on the PC800

I rode my Honda Pacific Coast PC800 motorcycle to work today. It’s been running well enough the last few months but I hadn’t really taken it on a long jaunt. As I was going through Sherwood, I started smelling gas. By the time I got to work, the bike was peeing out gas.

I disassembled the bike behind the office to try and fix the issue. A little premium gasoline and some seafoam, and I was able to get the float valve unstuck that was causing the float bowls to overflow and dump fuel out of the vent port on the back side of the carb. However, I can tell this problem is going to keep coming back. It’s time to search for a new carb. I’ve rebuilt this carb enough times that I’m getting sick of it.

Fuel Leaking from the Plastic Tree Between the Two Carburetor Bodies on the PC800

While I was working on my PC800 the other day I discovered that the carbs had gotten gummed up while it’s been sitting. This is the result. Fuel leaking out of the plastic tree between the two carb bodies. I pulled the bodies off of the bike, opened the float bowls, cleaned out a little bit of gunk that had built up and exercised the floats, put it back together, and it was fine. This is usually an indication of a stuck float valve or a flooded float body. It’s an easy enough fix to do in an afternoon.
