So, went riding for the first time on my 2000 426 yesterday and had a little problem with the idle staying high after getting off the gas. Like after doing a hill climb I would let off the gas at the top and it would idle much higher and not decelerate very well. I just jetted it a little richer and have not messed with the fuel screw. Could that be the answer if it were out too far? The bike idles fine after a minute of higher idle and starts easy.
