  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

250-500cc idle hang??? wont go away

The last video I think it might be good. What odd is the first video there is a hang. All I did is change the clip. I wasn't aware that you can clean up a hang by changing clip pos.

But the other day I had it way rich all over and it was hanging. So I'm confused on how I can lean it out and clean up an idle hang
 
I had issues with the JD red. I have 09 wr300,head mod , pwk with RB mods , aftermarket silencer. My jetting for 0-2500 ft , 50:1 mix , non ethenol 92 super.

CEL # 2
42 pj
178 winter
175 summer
 
Finally got a chance to try the red clip 5. Lol what a joke it bogged Sao bad I couldn't power threw it. My Ktm buddy had some needles so I tried his red clip 2. Wow clean as can be. I have no idea what the ktm300 jd red converts to? Anyone know? I got a CEL on order ascwell since it seems to be a popular needle.
 
On the top of the red under the clip grooves how many lines are on the red you computed to be close to the ceq? My guess is 2. I have two different reds. One has 2 and the other 3. Te red that came with my pwk has 2 and if it converts to the ceq no wonder I was having lean issues. That diameter is almost as lean as you can get.. I tried the CEL yesterday and don't like it. The taper is too rich for my taste. So I'm gonna try the CEM or CEN. My guess us the red with 3 lines will convert over to a CEO-CEP

maybe Im missing something, but did you try the air screw/Idle screw adj. (didnt read anything here about the air screw) By turning the air screw too much will make the idle run on higher rpm for awhile.
If you adjust the screw where you no longer have the rpm run on, and it wont idle, then you need to drop the clip on the needle valve. So adjust the screw 1 1/2- to 2 turns
out, if it doesnt idle drop the clip one or two nothces. Your muffler packing will effect the idle too, if its all gucked up.

Needle effects idle and off idle running, as well as the airscrew, all other jetting doesnt do anything to the idle. So if we set the idle, airscrew, correctly, then move the needle clip
is the way to go. We dont want to run any two st lean, so it needs to be a little fat all through the jetting. Again dont over look the packing in the muffler.

ohh, in the video's the bike idle seems a little slow, and I didnt hear any idle run on,
and you didnt wack the throttle hard enough to clear the bit of oil on the spark plug.

Yeah it's fixed. Current setting.
Ktm300 red 3rd clip
40 pilot
172 main

Runs clean from idle to WFO with a ever so slight sputter at 1/2. In clip 2 it's a tad lean for my taste but clip 3 is a c-hair rich. The Ktm 300 red converts to a CCN. Called sudco and ordered some needles. Now since each clip position is actually 2 steps I ordered needlesso I cam make 1 step st a time.

The second letter "xEx" is nothing more than 2 clip positions different compared to "xCx".
For example, the needle setting CCL#2 is the same as CEL#4.
Another example, needle setting CCL#3 is the same as CEL#5.
 
It sounds like to me it is scavenging for fuel.. which is causing it to rubn on..I would set your idle and then adjust pilot screw to the mid between highest idle and the lowest. Take it for a ride to clean it out, then readjust idle jet again... Mine does this when I get it too lean on the pilot.. I have a WR300 2010 std every thing.
