Just got a 2005 250F. Strange thing was the 1st starting. Pulled choke "on" and the thing would not start. Once choke was "off", and the throttle was cracked while kicking, she fired up. This has been the only way to start the bike, hot or cold - choke off, throttle cracked on about 1/8.
Runs funny. Idles up and down a little, and backfires when decelerating.
Strange thing is people say backfire is often a lean condition. If its lean, why wouldn't it start better with the choke on?
If I fatten up the pilot jet, wont that make the choke that much less effective?
Anyway, it was cold (high 40's), and I only adjustde the air/fuel screw 1/2 turn out.
Sounds like I need a 42 pilot, raise the needle one, and mess with the fuel screw. The choke thing has me befuddled...like most 4-stroke issues...
Any words of advice from those in the know???
