what size jet

[mud runner]

what jettimg should i use for a full dg no airbox lid and permix 32-1 i was thinking 280

250-270 prolly closer to 250. the dg doesn't really require going up but like one jet from stock(230) and the airbox is one to two jet sizes usually

 

[mud runner]

what about 260 main jet

 

[Blaaster]

With the lid on go up 2 jets for the DG, 1 jet for 32:1, 230+3 = 260, depending on temp and elevation.

Airbox lid off can make a difference of 1 or 2, so start at #280 and plug chop to confirm.

probably not much change but 280 isnt' a bad start
