4 mill jetting

[chevybanshee350]

Yes i have a 2004 banshee it has HJR mx hardcore porting, 65 mm pistons, 4 mill stroker 5 mill long rod, DMC alien pipes, 34mm keihin PJ carbs, no airbox, +4 timing . HJR said 158 main, 48 pilot, and needle on 3rd clip. This thing just has no and i mean no bottom end, and has no throttle response on the bottom end, but runs like crazy on mid and top. It almost feels like the choke is on its that bad on the bottom, ive tryed turning the air screws out, doesnt help, ive tryed the stupid choke/idle things at every postion, and it wont idle. Should i try a smaller pilot or what do u guys thick is wrong with it. Thanks

Try and drop down one or two jets the 48 should be ok maybe 50 also can try a 156-154 see what that does keep checking the plugs make sure ur not running it to lean, don't wanna fry that top end

Pull your reeds out and inspect the peddles! I bet a reed is cracked or frayed real bad

[chevybanshee350]

Just put new reeds in it . The main jet is fine ive done plug chops,little rich but nothing crazy.

Little rich on the main you say but wont come out of the hole?

[chevybanshee350]

Yes it runs amazing up top, but nothing done low, it just acts like u let the choke on, but it not. I have a 250r and its like a four stroke down low, but this banshee is driving me nuts.

Sounds like the needle is about 2 or 3 clips too rich.

Im i raise the clip to to make it leaner, will it mess with my main jet and make it lean too ?
