I have a '79 XS650. I just switched from the stock CV carbs to 34mm Mikuni carbs. When I start the bike now, my idle is ridiculously high, between 5k and 6k. I have adjusted the idle adjustment screw but that doesnt seem to really help. Right now I have the screw all the way on both carbs. If anyone can give any advice or suggestions, they would be greatly appreciated as I am kind of stumped. Thanks in advance.
