It starts ok it just wont stay running. You have to sit there with it for at least 10 min. babying it with the gas or it will die. After that it starts and runs great and will restart great. When I got it the dealer gave me a little plug that goes the hole in the air box lid that acts as a restrictor. Now can I get by with just adjusting the mix or do I need to rejet or do I have something else wrong.

All stock.

Thanks
Scott

This is where I got mine...I got a 42 and 45 since 40 is stock. It all depends on your mods but in stock form i would start off with the 42.
