I just put my ct pipe on, and can't get my air problem tuned in. If I put the lid and snorkle on, it runs good to half throttle, but bogs on top. If I take them of, it bogs 1/4 - 1/2 throttle. WTF? Will playing with needle and air mix settings fix this, or do I just need to find a happy medium and deal with the hick-ups?

 

what size core is in your ct pipe (small, medium, large)(quiet core, race core)

baffle size?

 

Full system, and we'll call it race core, it's the only one they sell.

 

did u change main jet????

 

yes. 165 Main, airbox lid removed, 3rd clip down on needle, air screw 2.5-3 turns out. It has a sluggish spot from 1/4 - 1/2 throttle where it's getting too much air.

 

i have a z400 with hmf slip on 165 dino jet and stock air filter 2 2inch holes in lid and 3 turns out on the air screw it pulls vary hard i love it.

 

i also have stock needle

 

If your runnin a 165 with a slip I wonder if I shouldn't step up to a 175 or so. I can't believe your able to run stock needle with your slip. when I cut out my pea shooter on my stock exhaust, I had to put a washer under the c-clip remove the cap on the snorkle and drill out six 3/8 holes in th lid to get it to run right.

 

Where does the main jet fit, iv fit the idle jet but coyuld u help me by telling which jet i replace with the 170 jet.

This is on a z400..
cheers Gareth

 

i would try a 170 or 175 did u turn your air screw out any?
