K&N Powerlid woes

[jobbyjim]

I installed a K&N airfilter a couple of weeks ago on my 2008 LTZ400 and it ran great. I just installed a K&N Powerlid and changed the jet to the K&N-supplied #160 Main jet. Buike is cutting out under throttle. Instructuions say to adjust the fuel mixture screw but my bike doesn't appear to have them (at least not what is shown in the K&N instructions). Any suggestions?

it has a fuel mixture scew ,but has a plug covering it. looking from the bottom of carb were there is a indentation in the carb bowl there is araised boss area that has a plug in it. u drill a 5/32nd hole in it ,being carefull to stop as soon as drill goes thru then use a sheet metal screw to screw into it and pry out the plug the adjuster is under the plug ,this adjustment will have very little to do with open throttle

at what point is the throttle cutting out? 1/4, 1/2?

I think that main they supplied you with is too large. I have a powerlid and a k&n intake with a slip on and im only runnin a 150 main. Do some plug checks and see what happens.
