Fcr carb

[Norris3710]

I have a fcr sudco 39mm race carb for my 400ex and i was wondering what the difference was compaired to the stock yfz carb, the only reason i was asking is because i was getting ready to replace the leak jet in my yfz and i had my other 400ex carb apart and realized the it doesnt have a leak jet.

if it doesnt have a leak jet, i bet it also dosent have a accelerator pump, seeing as i think the leak jet and a/c pump work together

it should have an accelerator pump. i have used those frc 39's before but i don't remember ever looking for a leak jet. are you sure it doesn't have a permanent leak jet?

It may be permanent, i do know it has an accelerator pump
