For jets,...a good starting point would be 17.5 pilots and 117.5 mains.

It sounds like there's one accelerator pump --- two would be unusual.tbird wrote: hey Steve . thanks for replay , yes has 2 pumps one square has rod on it and a triangle one on bottom ,

The triangular setup is a vacuum sensor --- I think it acts to shut off fuel to the accelerator pump when the engine stops. The thing is disabled at the factory on some models (such as my 81 650).

Only the 26mm 's had both diaphragms fitted.
The 28's had the triangular one blanked off.

3/16 seems like the logical size to try. Metric --- probably 5mm [(3/16) x 25.4 = 4.8mm]
And all 4 bowls should have a ball, weight & clip, and on the pump nozzles at the carb body gasket surface each nozzle should have an o-ring.
