carb fix

4 posts in this topic

Hi, on http://www.borynack.com/Bruce/XR650R/xr650r_caruretor.htm

There is a fix for the carb. Something about removing the choke flap of the choke plate. But what is it good for???

I get the idea of fixing the Air cut off valve, (I think) but not with this choke fix.

Can someone also please help me with the honda parts No for 70s jet, 178, 180 and 185 main jets.

Thanks,

Tom

Removing the choke flap does two things. First there has been a couple choke flaps that off and was sucked into the engine. If that happens the small spring and rod can make it into the cylinder.....not good. Second and not as important is that the flap makes some what of a turbulence in air flow. Once the bike is jetted right, the bike will start easier on full choke.
