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 The previous version was outdated and no longer supported.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

07 on the Dyno

Wow the poster says the bike is stock which means he has been riding around for 12000 miles with the stock exhaust (you can see it in the pic ) which has a highly restrictive cat exhaust !!!

My 06 gained so much power when i swapped the exhaust out it was ridiculous.

My "SOTP" dyno indicates about about a seven HP gain when properly jetted and a good free flowing exhaust.:D
 
I wouldn't take those numbers to heart. I've spent some time running bikes on a dynojet and there are a few things that I can see from this picture that are making a big difference with crank vs. rear wheel numbers.

BTW- I wouldn't be surprised if the 450 made more power than the 610.

True on the forast part.

As for the 450 -v- the 610. I own a 06 TE610 with a Barrett muffler on it and a bone stock (motor wise) TXC450. The 610 has way more torque and bottom end and i would guess more power everywhere. The 450 might have an edge on top but i doubt it. I think my 610 would leave my 450 for dead in a pavement drag race. Might have to do that one day soon.

I have no problem hanging with and leaving these two 650 twins...

Most of the "tests" that I have seen indicate that the 450 and 610 are pretty close when it comes to peak HP but the 610 delivers it over a much broader rpm range.
Yeah Kelly I think you are right that in a asphalt drag race the 610 probably has the edge over the 450, like the old adage goes " there's no replacement for displacement".
 
I was always told by a local dyno guy that knobbies and dyno's do not work well together. I watched his 45o KTM gain 6+ hp over a knobby when he spooned on a street tire.
 
Yes, I agree. There's a knobby on there and they'll kill a run. I've also found gearing has a huge effect.

450 vs. 610, Just as stated above, I think the top end HP number would be close, but the 610 will make WAY more torque and HP over a much broader range.

BTW- I think the 610's basic motor design is a great one and that's why it's still around. Husaburge and KTM basically used spin off designs to get into the 4 stroke market. It was the first truly competitive, light weight four stroke motor, IMO.
