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 The previous version was outdated and no longer supported.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

Hi,
I have a TE450, and now I own a WR300 as well. I picked the bike up over the weekend, but the bike won't idle. I adjusted the idle screw (on the carb with a jam nut?)..nothing...and then I adjusted the throttle cable...bike starts let it sit and it will die....clogged jet?

As the bike is stock, is there a sticky on all of the mods available for this bike? I love the smooth acceleration, bike runs good...I just need to get this idle licked.
Thanks,
 
i had the same problem with idle on my bike. ultimatly i ended up changing my carb to the Keihin PWK. Its still a bugger to cold start but im working through that, but it idles sooooo much better now... good luck!
 
What year 300? First of all, your throttle cable needs to have some slack in it. You probably have a clogged pilot circuit causing the problem. Take the float bowl off, clean anything that looks gunky. Remove the pilot jet and air screw. Clean the jet. Make sure you can see day light through it. Blow compressed air through it. Blow compressed air through the hole that the air screw fits in. Are you running a Mikuni carb? Make sure that you have the right size pilot jet for your carb. I ran a #45, then a #40 to get things close. The air screw should be reinstalled and turned in til it lightly bottoms out, then turn it back out about one and 1/4 turns. Set your idle after the bike warms up. If you have a Keihen carb, Somebody else will have to tell you what size pilot jet will be ideal.

that's not the AS. that's the idle screw and should not need messing with. back it out til it's flush with the nut, maybe a thread or two poking out, then lock the nut.

the air screw is between the fuel line and the boot. lil tiny sucker way in there. back it out 1.5 turns from all in after the clean out dirtdame suggested. if you are not familiar with the jetting process please take it to a mechanic. not a chop just saying its not worth burning it up. i got mine to go ok with the stock needle/nozzle with some fiddling but its super easy to go way wrong with the stock nozzle/needle combo.

i finally got the JD kit and replaced the jet nozzle with the #9, the red needle @ #3, 430 main, the rest per directions.

it was good before, it's outstanding now. just the sound it makes idling and coming down the trail makes peeps comment. and, move the hell out of the way.

if you hammer hard and are using the stock stuff do a #45 pilot to start, AS 1.75 out, needle clip in the bottom groove, 440 main as a safe baseline and trim from there. again, its easy to go way wrong with the stock nozzle/needle combo. if you try and lean anything out from this, turn the AS back into 1.25 to 1.5 at thevery max and keep reading that plug.

i HIGHLY recomend the JD kit at the very least, no room to type all the reasons, next would be the Lectron carb.

do you ever lay the bike over on its side until the gas runs out of the carb then pick it back up and kick. Sounds bad but it really does work when the bike is cold Just try it
