Exhaust flap moves from what I can tell from the outside,can see through honeycomb on one side of cat,most of it is missing on the other side. Also getting loud backfire out exhaust. Whats the chance of the material from the missing side of cat clogging the flap?
Just thought about the flap being clogged and reliazed it wouldn't matter since it's still running crappy with the cat section off the bike. I'll test coils after work tomorrow. Maybe valves need adjusted? Could bad gas be causing this much trouble. It seems to run worse since I changed the plugs though.
