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 The previous version was outdated and no longer supported.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

Husky 511 Dyno run

After being disappointed with the performance of the bike with race map 3 I purchased a Power commander 5 and tried both of Ziptys provided race maps (Big thank you to Tinken for providing these) the difference was night and day. Knowing that Zipty is 1000+ meters above sea level and I am only 250+ I thought it prudent to get the AFR checked out on a dyno. So myself and 2 friends went yesterday.

My bike has the Akra end can, TC airbox lid, PCV with Burson map installed. Below are the results.

Looking at the AFR it looks like it could do with a little more air, is there a race airfilter we can get for the 449/511?

Bikes run

Husky 511 SMR with Akra end can, TC airbox lid and PCV 43 bhp
KTM 690 with Cam work and Leo Vince exhaust 51 bhp
Husky 510 standard 47bhp
 
Just got my 511 back from BPH Motosports in Sacramento. He installed PCV and did dyno tune.
46.05 HP with FMF slip on and home-made airbox mods (extra holes).
Have only done one short test ride so far and tried to get it to flame out... Didn't happen.
Looking forward to a nice long dirt ride next week.
 
Not sure if more holes would help, too much air and you loose bottom end torque and I definitely don't want to loose anymore from the bottom.

I'm wondering if I can lean the percentages out a tiny bit on the burson map to bring it closer to 12.5
 
The "more holes" just brings it a bit closer to the way the TC's airbox is made. Sounds like putting a TC's lower airbox is a fairly common mod for the TE's. I don't know if bottom end is lost, but I'm fairly sure it will lean out the bottom end which means... in my opinion, one should have a PCV to richen it up or the added air flow will mess up the way it runs down low.
 
Was that 510 that made 47 a FI or Carbed bike? Wow, I had no idea the older 510's were so strong.
