No bottom end powe

[Noaly125]

Last week I found out that one of my carburetors was junk so I ordered two new keihin carburetors 35 mm put them on and now I have no low in power I can feather it through decoder half throttle and it comes alive the tighter the air screw the better it does it has 160 and 55 jets in it

I I'm guessing it's a knockoff now

Might be a problem ...160 and 55 seem awful Rich also?
What did you have before?

I've only had the four-wheeler for a week and a half and I'm trying to figure this out it wasn't running off of one cylinder because of the carburetor and I swept carburetor sides and it went to the other side so that is why I ordered new cards and now it will idle find and top in is fine but it's just a low end take off

Drop the pilot jet to a 45. See if it helps. If your carbs jet like airstrykers you'll end up around a 35.

Once you get idle and the pilot set, then start working on the main

170 main and an 65 pilot is what it took at the  motorcycle shop today
