    Let me start by saying THANK YOU for all the usefull 660 raptor tips i have gotten from you reading the forum as a guest over the years. You may not know me, but you have fixed my 04' 660 raptor many, many times!! anyway, since you seem to be the master of all things 660, i was hoping i could pick your brain for a minute. my machine has developed an off-idle bog. meaning if its idling, and i stab the throttle, it will almost die. i can roll on the throttle slow and it absolutely rips just like it always has, pointing the front wheels to the sky! but i cant seem to get rid of the low rpm bog. just past the low rpm bog point, i can punch throttle hard as i want and no problem.
    im so confused because it has ran AWESOME for 2 years now since i rebuilt in in 2015, so im sure my jetting and fuel air screws are good, but i am lost on this. any input would be awesome. thank you for your time.
