Title: YAJQ (Yet Another Jetting Question)
Post by Greg on 06/17/12 at 18:31:37

My jets should be here soon. I have been reading everything I can find on the jetting procedure. I am going to attempt to rejet with carb installed. I am just wondering if I am understanding my jet size starting point. I have a Dyna muffler with a 1/2" hole in the baffle. Not quite straight through but getting close. I have the stock air filter with no immediate plans to go to a K&N or cone. I am not doing the white spacer mod either. From what I am able to piece together I should start with a 152.5 main and a 55 pilot jet. Does this sound correct?

Id call that a good start on the main, IDK about th pilot.

Whats your elevation above sea level?

If you were in Colorado,, that mite be a bit rich of a setup, but down there, I think it makes for a good startin spot.
I guess if one of the Carb Gurus steps in & says otherwise,, I was WRONG,,

Its the best I have to offer. Thers a few guys here who have a better grip on jetting, tho. If one O them pipes up & has a different idea, ditch what I said & go with them. If I was guessing, Id guess you may be a hair rich with that main, but not a lot, & the pilot? Ehhh,, it doesnt sound far out either, Id be interested to hear what others say, Youll know in a short while & the solution is easy,even if youre a bit rich, who knows, it may be a great setup. Anyway, Id rather start a hair rich ,,than lean,
