AFAIK the only after market jets you get for mikuni come in those ghetto carb rebuild kits you can buy, and the jets are trash.

Buy genuine Mikuni jets only! You can get any jet you want from sudco or jetsrus, or your local dealer, as was wisely suggested.

My advice would be to buy a couple of each in larger than stock sizes so you can see what difference they make. Alot of the time if you find yourself wanting to try an even bigger jet the dealer will simply trade you for one of the ones you just bought. That and you don't have to pay shipping.
