I did a search and couldn't find anything on this. My search criteria may be off though.

I installed a K&N filter into the stock airbox on my Predator and now she wants to shut off at idle. Once warm, it shuts off less. Other than that, I can tell that the throttle response is better and the butt dyno seems to pick up a little more power.

Should I need to adjust the carb just because of a filter change? I would have never thought it would make that big of a difference.

Any help is appreciated.

 

its their garentee that you dont have to, but i would amagine with a large intake like that you might

 

You might have to play with the idle mixture, its probably a little lean with the filter.

Lets face it, we buy those things, because there is a difference.
The kn will flow alot better, so the mixture is probably leaner. If the idle is the only problem, then make the idle circuit richer, by turning the mixture screw ccw.
A warm motor, will tolerate a lean mixture better than a cold motor will, thats why its worse when cold.

 

yeah, your lean at the bottom that's why it's cutting out on you

 

I put the choke on half way when starting it until it warms up and once its warm it starts fine. I have the same problem after i put mine in.

 

Thanks for replies. I didn't get to ride last weekend, but I plan to this weekend. It seems that once I warm up, it gets better.
