Hi James. With pods on you are running way too lean with 102.5 main jets - a 1000 fitted with the standard airbox and zorst runs well with those. (I presume 79 = VM carbs)

You need to go at least 130 on the mains and raise your needles - try lowest clip position first. Trial and error is the only way. If you aren't experienced in setting up carbs and still have the original bits you can save a lot of time and grief by reverting to original.

Take some time to search this website. That question gets asked a lot. There already are many great posts about how to get your jetting right. In fact, nothing personal, but that question is just so common that you might find that people don't answer it. Seriously, search the forum. The truth is out there. Welcome to the board.

Hi James. Where do you hail from. Do your needles have the grooves in them.

Buy a DynoJet kit and be done with it.

[James]

[James]

The Way It Was Acting I Didn't Know what Was The Problem The Carbs Are A Lot Different Than A holley 750

I hope you mean the lowest groove (closest to the middle of the needle).

The top groove (closest to the end) is the leanest.

[James]

Yes That Is What I Mean Is The Lowest Groove Thanks
