Need part numbers for oil pump and check valves

[mcutcher]

I have a 1994 200 (200TJRS) that is leaking fresh 2 stroke oil from the air silencer. I pulled the tube off the bottom of the silencer which goes to the crankcase and it drips constantly with motor tilted up or down. I read from other posts that tell me, I need to install check valves and possibly replace the oil pump. Does anyone know the correct part numbers to order? Or does anyone have a cheaper but effective remedy?

Thanks, Matt

Depends if you have original Keihin oil pump or later Mikuni pump that replaced the Keihin pumps. On the Keihin the check valves are part of the pump. On the Mikuni they are in the lines.

You can add the check valves to the lines of the Keihin pump but the valves are not cheap.
