okay,the stock main jett is #58 right? so the bigger number = bigger hole?so 60 would be bigger then 58 and 57 smaller

Can you drill out main jetts using a numberd drill bit set?

yes you can, but it could cause some confusion down the track.

Agree. Jets are cheap to buy. Get some and try them out.

well i drilled out my 58 to a number 60 drill bit and too rich,so where would you guys suggest i get bulk main jets for cheap?

I just bought one from my local shop for $2.50.

DRATV sells them in singles and Hondatrailbikes sells them by the set. Check your jet type before you order.

Note, jet numbers don't line up with drill bit numbers in all cases. I can't remember which is which, but I believe Mikuni marks theirs by their own internal 'flow' rating, while Keihin uses metric sizing, measured in microns.

You'll find that the jets sold by Trailbikes are for the 20-26mm Shengway carbs, and are a different type than the stock Keihin ones used in the OEM Honda carb. They will not work on the stock carb.
