  • 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 The previous version was outdated and no longer supported.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!

125-200cc Slow/Strange Return to Idle

Hi Everybody

2012 WR 165 with KTM 200 pipe.

Having some issues getting the bike to run right following installation of the 165 kit. As you can hear from the first 20 seconds of the video, the engine exhibits a protracted, unsteady return to idle after the throttle is blipped. Also the whole response from the motor is off. It's whatever the opposite of crisp is. The engine just sounds off and "fluffy".

I know that unsteady return to idle is a classic symptom of too lean on the pilot circuit but this issue can't be dialled out by playing with jetting.

i have: checked for air leaks, checked the reeds, checked carb float level, fresh air filter, fresh silencer packing, fresh, correctly-gapped spark plug and tried different base gasket thicknesses. I tried VP race fuel in case its a fuel issue. Nothing answers.

Anything else anyone can suggest please? Timing? Help, I'm seriously considering putting the old 144 kit back on as I'm getting tired of messing with this thing!:confused:


 
Thanks for the replies and the suggestions everyone.

As for jetting changes, I went up a size on the pilot jet but it was really blubbery just off idle so I went back
 
Was the return to idle better with the bigger pilot? If it was then perhaps the richer pilot with a leaner needle might be worth trying.
Be sure you are taking note of throttle positions and not engine speed. "Just off idle" could be pilot and airscrew, needle straight section or even clip position depending on where your throttle is (1/16 through to 1/3 open).
