What size jets do I need to run on my blaster?

[Motomayhem]

I have a toomey b1 pipe no muffler, straight piped, and a uni air filter no air box. Has a cheap Chinese carb from a top end rebuild kit. Is bigger than the stock 230 size I compared them what should I try?

Do genuine Mikuni Jets even fit that carb?

I would start at 300 maybe even 310-320 depending on elevation and temps and plug chop down from there.

I have a Mikuni carb that came with it, the slide got stuck so I filed that little nick down and will start running it; do I need to change the pilot jet as I up the main jet?

Adjust for your temps and elevation. Plug chop.
