TE/TC My One Fiddy

Good eye, there is no difference in that picture; it just shows the new parts. This pic shows the old and new barrels.

jon super nice looking shop man love the OG "molester" van hehehe kidding of course....nice rig. no windows. cant see the husky inside keeps prying eyes away. my riding buddy had a white one just the same and we'd jam pack it with two huskys and gear for rides at weekends end it was pretty nasty inside hehehe gear fast food junk pop cans. impressive work you are doing sir. love the turndown tip.

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.

Winter project:

Did a little more work to the Keihin, getting ready for spring.

I wonder how well the INTELAJET works?

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.

Gentlemen, welcome back. I was told to make these center hubcaps for the Boss’s Chevy Colorado before the shop closes. :-)
She also rides a TE150.

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.

I’m just a rookie at this engine stuff but I’m trying my hand at designing and machining a prototype combustion chamber insert for my bike.

It’s more compression than stock but a little less than other aftermarket ones.

Sweet work John! How wide is your squish band?

The design above squish band width is .375 and .037 deep at the outer diameter.

This other slightly different head design’s band width is about .03 less with a depth of .025

I also made a set of heads out of copper. This stuff is a bitch to machine and very expensive but what the heck I thought I’d give it a try.
I’ve been called a lot of things but being smart ain’t one of them.

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?

gotta be heavy... but good heat conduction.

what makes copper so hard to machine John?

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.

He married me... I'd say he's pretty smart!
