Hello everyone - last year (2010) I bought a new leftover '06 WR450. It ran great all year and most of this year. Over the summer it sat for a few months and when I fired it up this fall it now boggs and runs very rough when I open the throttle quickly. With the choke on, the bike idles very high (as expected) but has good throttle response, and runs well. I havent made any adjustments to the carb or adjusted any of the jets from the dealer set up. The only thing i've done is turn up the idle speed a bit to prevent stalling (when the bike was running properly early in the year). I've since turned it back down (i think) but I'm not clear on exactly the right setting. I dont have a lot of knowledge around how carberator settings work on a bike like this and would greatly appreciate advice on how to get the bike to run / idle properly with the choke off. Thanks!
