I had some slight issues with my Riva 125 so I decided to clean the carb. Discovered some monkey messed it all up:huh I can't believe this thing was even running! Multiple issues, but : The electric choke is showing an open circuit - not good. Plus it looks as if someone took the black plastic barrel off the metal part and removed a pushrod with a beveled end that pushes on the cam which depresses the choke plungers. I don't know - never seen one before, but that's how it looks in the manual. There's a brass piston inside the plastic deal that looks like it's extended pretty far but no way it could contact the cam, plus the mating surfaces wouldn't match up. I there any option other than buying the $200+ plunger assy from Yamaha? (I did find it for $159 at least). Has anyone just permanenetly depressed the plungers and ran the thing with no choke function? Will it even start? I'm on the RivaRiders Yahoo group but every single message has to be moderator approved:huh Takes forever to get any answers.
