Just wondering what everyone does for main jet supplies? Think I'm going to need a few while setting up and my rgv ones dont fit!

you can get main jets from honda . the parts numbers are shown in the tuning section on this site.
Main jet part numbers follow this pattern: 99101-393-xxx0 (where xxx is the jet size required). E.g. a 185 main jet has a part number of 99101-393-1850. This formula can be used for EVERY 250 NSR, MC16 through to MC28

i get mine from allens performance , give them a call you will get them the next day

I'll second Allens. I bought a kit from them, running 130-150 from fleabay, so maybe try searching on there...

I've used them too - went in person to their little shop/unit in Bingham (i used to live in Nottinghamshire) - they have a bunch of display cabinets with various carbs and bits and pieces on view. Bought a load of main jets for the MZ race bike.

Ideal, thanks guys I'll give them a shout!

Oh and to save me digging the carbs out, what size are the jets? I know they are keihin slots but what head and thread size?
