  • 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 The previous version was outdated and no longer supported.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 WR300 sputtering after a fast wide open run...

Just wondering what could cause the 300 to sputter occasionally after blasting wide open for 5 seconds or more ? Could the bowl be runing empty?

Overall she runs great now with the 170 main jet and 40:1 mix.
General riding is proving hard to keep the front end on the ground even when running 14/45 gearing. Next week I will go to 15/45 + the race head :)

At no point does the 300 feel like its under powered now. My mate (on his husky 510) and I did a rolling start at about 40klm hr to full throttle yesterday and the 300 stayed head to head all the way :applause:

Loving this bike :)

Put a fresh plug in it....do a warm up by shifting through gears no more than half throttle to warm it up then build you speed up to hit 4th gear WOT, pull the clutch and hit the kill switch...otherwise known as a plug chop :)

If the bowl ran empty the bike will noticeably over rev at some point.

What was your throttle position when it started to splutter...3/4, 1/2 or 3/8?

To me it sounds like the the combo of needle height and pilot jet...maybe even the type of needle.

Do a plug chop.
 
Yes, what throttle opening does the sputter happen at? It might well be a bit rich at that point. The 5+ second blast heats things up and will bring out any marginally rich spot in the carburetion.
 
Cool picture , BTW. Looks like you're having fun!:thumbsup:

Better watch you don't dig up an oil well:lol:
 
Cheers :). It doesn't appear to happen on short bursts, only after a longer wide open runs. When i let the throttle off from a fast run and then try and cruise at a slower speed it runs a bit rough from idle up. Give it 10seconds or so and it's ok again.
 
My '09 did the same thing. Lower the needle one clip and see if it helps. That's all I did and mine quit.
