XS400 air pilot jet?

[armyofda12mnkeys]

Hello all,

I'm looking for the lil screw-in jet on the left side on the back of the carb.

I think its different than the 'pilot jet' which is inside the carb.... This is called the 'air pilot jet'.

I think the values on that hole are 170 when i looked at it (but on backup carb i have I think i saw 155), not sure whats stock.

I think the 'air pilot jet' is #52 here (vs #12 for the 'pilot jet'):

I think my is a bit stripped so i was looking to replace. MikesXS has 'pilot jets' but i didnt see 'air pilot jets'

Thanks!,
