Jetting driving me nuts!

[Lethaface]

Ok here's the deal..I recently bought a Speed Tech ported cylinder..I bumped my main's up to a 320 from my old 280's..So i was riding about 3 weeks ago and it was running great and then broke a reed petal..For the price of stockers i just bought a set of TDR's Hyper tension reeds for a ported banshee, and ported the reed cages..While i had the carbs off i noticed that the old owner had the air/fuel screw almost 6 turns out..So i took it back down to around 1 and a half turns out and now i am having some hesitation in the top end..I'm not sure if its being caused by me turning the air screw's back in or if the reeds made that big of a difference on the jetting..But i know that the air screw should not be 6 turns out!!..

 

THe problem i am having is i will be going through the gears and right when i get into the heart of the power band, it will hesitate for a brief second and then start pulling again..It sorta acts like for a brief moment the motor lost gas then catchs and bulls like a bat out of hell..Anyways its driving me nuts..The current set up is stock carbs with 320 mains, needle clip is in the center position, and stock pilots(27.5's should be here monday)..I'm at 3,000 feet elevation..The motor is ported with DMC 916 exhaust, TDR reeds, and milled head putting out around 150 lbs of compression..If anybody has a idea what is going on i would greatly appreciate a tip as it's driving me crazy!!

lean mid

 

raise your needle

This could be totally retarded but dosn't rasing the needle make it leaner? I could have it backwards but i thought rasing the needle made it more lean?? I'm probably wrong though, your advise b4 worked good on the pipes..come to think of it i think i did go from the 2nd from the top to the 3rd from the top when i was rejetting...I went out and noticed the left leg side carb was leaking slightly out the float bowl overflow..So i got to go out and make sure the floats are within specs..I'll try it out when i'm setting the float..If that doesn't work i'll just take a pic of the plug ..Anyways thanks again wes

raising the needle is lowering the clip which raises the needle. 4th clip from the blunt end.
