I'm rebuilding carbs and keen to keep it all stock.
They are Keihin VB42, I've bought a rebuild kit which came with different jets [some numbering on top, others with numbers on the side]
Originally the carbs had 68 and 100. Rebuild kit came with 102 and 89.
Can anyone assist with the standard set up is on these?
Cheers

68 in the front spot for primary and 100 in the back of carb for secondary.

The 102s will work in the back and for a K since the exhaust flows a slight bit different.
