  • 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 The previous version was outdated and no longer supported.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 WR 300 porting?

I'm new to owning a 2012 Wr 300 (6.8 hours new) and I was having issues with it falling flat in the mid range. This was after putting on the pwk carb also so I took it to a well known fellow near me to dyno tune it. While its there I have the option of porting it out and was wondering if anybody out there has done this? Is it worth while to create more power all around? Am I wasting my time and money? Any feedback is much appreciated!
Cheers!
Chris

I would take a deep breath before going in any direction, the bottom pulling power is what makes it so great to most
now let me say I have a 360 and not a 300, albeit the same architechture a different bore stroke combo
on the 360 the word is to reshape the intake behind the carb as it seems to be the biggest constraint past lower mid range
I was getting ready to do that to mine also and will post results
 
porting yes iam porting one right now .2premo is correct slow down .make sure your jetting is correct. pipe combo is what you want. gearingis usually to tall. head mods are important 250/ 300s.stock huskys have that double power band.problem is in pv design /jetting/gearing.300 porting is different than 250 slightly .port timing is good on both .husky copied honda cr 250 port timing wich was great.you can fix your probem with out porting.porting will help . do other mods first and you will get to know your bike that much better.huskys improve dramatically with small adj .this in my opion shoud have been done at the factory.
 
I bet your using a jd needle,I had the same issue.Try a CEL needle in the middle clip. You can get them shipped to your door for $9 on Ebay. Huge improvement over the jd needles.
 
yep i'd fiddle with the carb you can't unport it if you don't like it your screwed why did you not get a lectron?
 
It is the JD kit, blue needle I believe. 175 main, southeast PA, 50's when I rode it. I went with the pwk because of availability and the fact I didn't know anything about the Lectron when I purchased it. Prior to finding this phenomenal site! I dropped it off to a guy around me who's been in the business forever, always kept me happy. I'm gonna hold off on porting it and see what its like when I get it back. Ill keep ya'll posted with results. Thanks for the input!
 
I'm in southwest pa,My jetting is 45pj 172mj and CEL needle in the 3rd clip. My bike does not like anything above a 172mj,once it is above 60 I will drop it to a 170mj. The blue needle is very rich,the red is better but wouldn't run clean unless it was in the leanest position.
 
I have 175M Red in the middle and a 42 pilot and the bike runs clean all around....starts 1st kick and pulls great all over. Sounds a liitttttttlle pingy in the mid range but gets 22 mpg in So NJ enduro racing.
