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 The previous version was outdated and no longer supported.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

TE/TC My One Fiddy

Pvduke, thanks for the compliment but I will be retiring this year, I do have some other projects I’m working on before selling the shop and will post them soon.

a work shop that sweet is like a favorite dirt bike...sell it and regret will soon follow! i hear ya though...but man wow thats nice. hope yer diggin the 150. i was on the fence with that one or the TC 125. but i was stepping down off the open class smokers and wanted the lightest bike i could find for these old bones and after 30+ yrs on the 1/8th ltr i missed not having one the passed couple years and since i didnt need lights and all the enduro stuff i got the TC 125 saved a bundle and put the TE 150 tank on it, perfect fit BTW, that a sparky and barkies n bash plate and done for off-road basically mreep mreeeeep. but man the 150 is NICE. really nice. im afraid if i rode the 150 first i prob would have gotten it and not Trigger! hehehe.
 
Nice shop Mr Bunker. I only wish mine was that clear and clean. Only have 1,000 sq.ft - and four project cars taking up dirt bike room.
 
First I've heard of the Intelajet. Have you just installed it or have you run it for awhile? OK, I see it's on the Keihin carb, have you tried it on a Mikuni? More details please when you have time.
 
she's a keeper man....nice stuff

nice install on the jet seen those plumbed into the boot and what not and that's gets pretty messy pretty quick good job john

I haven’t installed it yet, waiting to finish another engine project I’m working on.

You have to make two modifications to the carb body to mount the Intelajet so I won’t be using it on the Mikuni.
 
Is there a performance expectation for the copper? They're too pretty to hide under the coolant shell... perhaps you should make the shell out of copper, too?
 
The SXS head from KTM Hard Parts are made out of copper too. :-)


The grade of copper I used was highly pure, not alloyed. The material is somewhat soft, well at least compared to a tool steel but also pretty tuff so the chip was hard to break meaning it was hard to control.
 
I'm John's other half... I'm running the Lectron, but thinking as soon as I get the $ I'm going to be changing carbs too. My Lectron is pretty dialed now, but still lacking a little. He's making extra, so I don't doubt one of those heads will have my name on it. Currently also have the RK Tek one. These 150's are FUN FUN FUN! And I have to add: John is still the best machinist I know. No brag, just fact. And having the toolroom access I've had, it's saying a lot.
 
I can understand those who might doubt me for using copper for cylinder head inserts.
But copper is an excellent conductor of heat, it has a much higher thermal conductivity than aluminum, Cu is 401K compared to Al which is 237K.
Aluminum is able to radiate heat into air better than copper only because of its lower density but when used with liquid cooling copper allows heat to pass through it quicker.

The reason you don’t see many copper heads is most likely cost, the copper material I used was industrial grade C10100 at $62 per piece where the aluminum grade 7075-T651 was $16 per piece.
