Carb issue driving me nuts.

[duck9191]

I put an aftermarket exhaust and a pod filter in place of my airbox on my storm. Now I'm having a hell of time jetting it. I've tried with my stock Pz30 and the pz30b I got from Tako with the same results. Idles beautiful, past quarter throttle it falls on its face, full is OK for a second. I have tried a 34-42 pilot with neat the same results. Also have tried 110-20 main with no luck and a the af screw between half and 3 turns out. Only other thing than changed is I adjusted the valves when I had it apart. Ran perfectly before this adventure lol. I attached a video of me rolling on the throttle in nuteral. Once you get to near 3/4 throttle it clears up, at least in nuteral. While in gear if you crack it full throttle it takes of for a second and starts sputtering, adding choke doesn't help either so I don't think it's lean .any suggestions?

Since it clears up at 3/4 throttle, I'd shim the needle to raise it up.

Forgot to say it is shimmed some, the stock needle is not slotted so I'm shimming with machine screw washers. I need to measure the needle off the other carb I guess and see where this one stands. Swapping needles can cause issues of its own.

Ugh, I'm an idiot... Cheap ass pod filter I got off amazon is the issue. Inside diameter is tiny, never noticed. I blame Amazon because the unifilter I wanted was out of stock lol. Took it off and jetted back up and its 90% there. Currently have it at 45/118 1.5 turns. Has a flat spot at the 3/4 to full transition I need to tune out but the damn thing goes down the road again! Will probably drop to a 42 pilot as it seems rich down low.

Several ppl reported the issue with them cheap pod filters
Stop buying them folks!

MtnManPoe had the exact same issue with that pod filter. Poor fella bought 2 additional carbs and a slew of jets for his Hawk before figuring out it was the filter. Be sure to post a long nasty review on Amazon so others don't fall victim to that garbage filter.

Do any of you guys have any links to some better quality two stage pod filters?

[NzBrakelathes]

Leave it stock
Easier simpler less drama

Uni 2-Stage Angle Pod Filter - 44mm I.D. x 102mm Length UP4182AST https://www.amazon.com/dp/B000WJIX6W..._RSLFDbY5J9N8N

Unifilters are normally solid, oil the foam if it's in a dusty environment.

I have had great luck with the cheap ($10) 43/44mm I.D. angled dual foam pod filters from ebay. I have a couple on hand to swap out so I always have a clean one. No inner restriction on them.

[duck9191]

Going to order a foam one, do you remember what ones you bought Dan?

Got the unifilter in the other day, good as new.

Rad. I have washed and re-oiled mine several times, once a month for a year. I bought the 20 dollar KN oil spray and cleaner spray kit at auto zone. I’m guessing the kit and filter are probably going to outlast the motor.

I have a K&N kit somewhere in the garage. I ride most on road so it should stay clean for awhile. May put a sock on it to help keep water off it if i run into rain since there is nothing blocking spray off the tire now.
