what is the bike doing.. Popping , hesitation, no idle ? Have you made any changes at all removed air box lid or anything ?
^^^^^ Just so you guys know, this guy knows what the F he is talking about.
He built the 426 in this bike with the 450 cams and it was a monster. Cranked on the first kick which is bad ass for a 426 until I let it sit up for a winter and clogged the carb. Rebuilt it and walla back to a one kick start.

All of the above. It was completely gummed up, I replaced all the Jets, needles, e t c., it was a complete kit to rebuild both carbs. I used the stock mixture settings, which I believe were two and a half turns out. Since I inherited the bike, I don't know exactly what has been done, but I do believe it was jetted previously. I also know that it has a full exhaust system on it.
So after cleaning the carbs, and replacing all the stuff mentioned above, I can get it to start with the choke on, but it is a rough and high idle. If I try to give it any throttle, it dies. If I try to take it off choke, it dies.
sounds lean to me. check the numbers on the jets you removed. If someone put a dyno jet kit in it they will be way off from what a regular jet says. If you have the air box lid removed put it on and see if it gets any better. just some info I googled on basic jetting for a piped 660 raptor also be sure to drain the tank and start with fresh gas.. be suprised how many people do not do that.
160/165. #25 pilot jets at 2 turns. Raising the clip drops the needles making it have a lean spot off the idle circuit. You want to put the needles back to stock or lower the clip which raises the needles
