Yfz450 Idle Problem

[YFZ450Rider]

Hey i jus put a dubach racing slip on my 450 and rejetted it with the GYTR jet kit, followed the instructions put all the recomended jets and needle settings played with the pilot screw, and adjusted the idle knob on the carb and now my bike wont idle. it runs amazing, but as soon as i let off the gas and the RPMs begin 2 drop the bike stalls. and when i start it i have 2 give it gas and hold it. there is NO idle what so ever... can anyone help me? PLEASE

Turn Up the Idle Thumb Screw on the side of the carb until it idles without the help of the throttle and go from there

still sounds more like the pilot screw to me i ran into that on my honda after a blown head gasket. but also check your slow jet for any restriction.. its not a very hard job to do.

What pilot jet did you put in it??? It's probably to rich at idle. What is the mixture screw set at?
