Just wondering if anyone can give me some advice. I was riding on the highway at about 85 mph and my Katana started spraying oil all over me. Didn't lose power or anything, but I stopped immediately and turned the bike off. It proceeded to leak the rest of the oil. Got it back to my place to inspect it to see where the oil leak was coming from. Filled it up with oil and no leak. Turned it on and oil seemed to be gushing out of the slots where the spark plugs are. I ended up taking off the valve cover and cleaning everything up in there and replacing all of the gaskets, as well as replacing the spark plugs. Put it all back together and it runs like crap. Full choke and it'll barely run. Any ideas or suggestions?
