Ohh, I am going to pull out so much hair!!!! So, put the carbs back on, bike ran ok cold, warmed up kept bogging down. Went out this morning, and looked it over, discovered I am an idiot! When I put the carbs back on, I somehow pinched one of the fuel bowl drain hoses, between the carb boot, and carb body. DUH! Big fat air leak. Sprayed WD-40 in there, and it immediately sucked right through the gap. So, re-pulled the carbs, re-installed correctly. Runs a lot better. But, still a little rough. Pulled the plugs, and weirdest thing, the front passenger side plug looked brand new. I mean shiny, white tip brand new. Put it in the plug wire, and started the bike, it is throwing a nice spark. Just to be safe, put in another plug, runs even better. Still a ways to go though. I did discover the "slap/knock" sound goes away if I pull in the clutch lever. Wonder if that means bad clutch? It shifts well though.
