you should have orfered a manual with that to find out the stock setting

tigmaster · 05-27-2008, 07:29 PM

Are you talking about me? What does he need to find stock jetting for? He has issues that heavily change jetting. Also with the addition of a pipe and reeds that actual seal, his jetting will change lots. The pass technique is going to be best. Leaves no guessing to be done, well technically at least.

i was talking about him, meant to say ordered, not offered

tigmaster · 05-27-2008, 08:23 PM

I see know. He should hopefully have no trouble getting it dialed in now with working parts.

well this is to doomed, if you do get the stock jetting numbers, make the main jet one size smaller and the jet clip one notch lower because of your elevation, that should get you close
