1991 KDX 250 D1 idles very rich and low
Posted: 02:15 pm Apr 03 2017
I need some advice.
Got a 1991 KDX 250 D1.
The bike just,just idles with idle screw all the way in. When I ajust the air screw, nothing much changes. Idle wont go up. It is also smokey at idle and very rich. Even the choke makes not much difference.
Run a 165 Main Jet, R1367N needle, #5 Slide and 35 Idle jet. I've tried a 42 idle jet, but with the same results.
The bike runs great past idle to top speed. Not to rich or to lean.
Just the rich slow idle I struggle to fix.
Also set the float level and cleaned the carb.
Could fuel leak past the needle and needle jet at idle. (Worn needle or needle jet?)
I've tried a Husaberg 300 Carburetor. The bike then idled a bit too lean and too high, but also ran great.
Also tried the Husaberg Slide and needle in my (PWK 38)carb, but then the idle was to high and lean and bike sputters at midrange.
