I hate to be a thread hijacker but I've got more turbo crank questions for you Slipdog....

Is this mod available to the public? How much does it cost?

Is engine life affected? Where does the power gain tend to be, bottom, mid, top, everywhere? Is this one of those "gotta be fast to be able to use it" mods?

If this is so good, how come none of the OEMs ever incorporated it into production? There's got to be a hidden drawback, right?

I'm fascinated by this thing dagnabit!

MX563 I agree. Those cranks are a work of art and a jaw dropper!

Yo newmann and fte or anyone that can help. Im looking for a Thor or Thor-type swingarm for a 77 RM125. My Fox bike is nearly done and thats the only missing part. Got original Simons that Thor Lawson is restoring, 17.5" Fox airs, a Doug Childress cone pipe and all the trick , works-type Aluminum billet pieces , but that swingarm is an elusive pain in the ass .

PS Didnt mean to hijack the thread, sorry

Coolest things I ever made was were these 2-stroke turbo cranks, of course I was trained and instructed by the original designer "Dr." Dave Myers of CPE racing.




I remember these being a big deal here in the Midwest back in the late 90's-early 2000's. my memory is foggy but I think both Jackson Performance and Hickman Racing were pushing this technology. Always seemed to be shrouded in secrecy and I never did get to examine one in person.

I made my own seal drivers and a soda blaster.

I built a YZ150 engine that pumps out more hp than a 150SX across the whole powerband.

I built a nice moto van.

My problem is that I want to build and fabricate all kinds of stuff but I do not know how to operate a lathe or milling machine and do not know how to tig weld. Over the past few years I have bought a small 3 in 1 Smithy machine and a really nice watercooled tig for the shop at home. Finally have gotten around to getting the shop close to being finished where I can finally start setting things up for use and then the learning process can begin. Pretty much anything I fabricate now has to be done with basic body shop tools and it kind of sucks. Burnt up a lot of favors over the years and painted a lot of dirt bike parts in exchange for machine work and welding jobs.Woohoo
Fly me out for a weekend and I'll show you how to use the mill/lathe and tig machine. Everything from threading, fly cutters, tapering and walking the cup/weaving in tig......man I just wanna see your stable up close.....hahaha

Har!

Bike stands both roll up work bench type and the toss around ones, assorted brackets, a wheel trueing stand. I'm sure there is other piddly shit I'm forgetting. But yeah just piddly shit.

-No, everything to produce them is packed in storage since I passed on the buyout opportunity a few years ago. The labor to build the crank only was $650.

-There was no difference in longevity of top or bottom end. Power gains seem to be across the board with maybe a slight increase in gains the faster the crank was turning, so not a pro type top end only with no bottom. My first time with one in '92 was with an already built motor so I got to see what just the crank alone did. It made my already fast motor launch harder out of corners and rev much further on top. So much of the powerband is controlled by port timing in a 2-stroke that we still had bottom-mid SX motors and mid-top outdoor motors.

If this is so good, how come none of the OEMs ever incorporated it into production? There's got to be a hidden drawback, right?
-This I can't answer. I can tell you they built a lot of outboard racing cranks for Mercruiser and was negotiating to supply a large volume, but the contract never materialized. Also in '92 Kawasaki purchased several cranks for "testing" during the outdoor season, but would not confirm or deny if the used them in the race bikes.

Reese, those are foot peg mounts off a sachs or DKW. My deek has the same type of mounting system.

I've made quite a few paintings and hopefully a few people happy with my work.

Funny but no one has put "a lot of money!", but I guess none of us are in this sport for the monetary rewards. Just making moto-art, doing what I've always dreamed of doing , is worth far more than money can buy!

I made a bike carrier for the trailer hitch to use on the back of my pickup truck. It incorporates a Bike Shoe to hold the bike, so no straps. I also built in a stabilizer for the unit so the carrier and the bike are rock solid during transport, unlike any other unit out there. Total cost was under $100 including the Bike Shoe.
Paw, did you ever get a chance to round some pics of your bike carrier?

Anyone that's raced an 80's era bike knows that most of them are set up for a midget, with the bars mounted in your lap. Since custom making a top clamp with a modern bar mount position is cost prohibitive, I make a plate to relocate the bars forward about 1.25". It's an easy fab, works great and allows you to ride in a modern over the front body position.

Does the front # plate still bolt right on or did you have to do some adjustments to make it work?

And in regards to 80's bikes having the bars in your lap, I look at old pics of myself and cant believe how far rotated back I had my bars. If only I had a further forward riding style in 86, id be a millionaire from all my championships.Wink

The front plate still bolts on with no adjustments. It's amazing how much more effort that old off-the-back riding position requires. Everything gets easier when the bars get moved forward.

Just a complete off topic thought here but...

I sometimes think when the subject of comparing riders from different eras is brought up that the current crop of riders from Bradshaw on, if put on a bike from 1978 and racing against Bob Hannah, Roger DeCoster etc., would completely dominate based on that forward riding style they would adapt to the 78 bike.

Riding techniques have improved as well as equipment, so if you could take a modern racer back in time, he would have a huge advantage. I also think champions are champions and if guys like Hannah and Decoster were born 30 years later, and had knowledge of modern riding techniques, they would still be winners.

I built up a golfcart for running around at the track. Its a 1988 metal body EZGo 2 stroke.
Before

During



After


I built the lift, bumpers, and rocker covers. Painted the body, powder-coated the red parts, new seat covers and wheel-tires.
Put the graphics on it for my sons company.

The Fun Mover on my profile pick, I rebuilt it also.

I get to make stuff like this every night at work. I work in CNC in a tool and die shop. We don't build too many complete dies in house and they are small if we do. We make all of the trimming inserts that start as billet chunks of steel. Thenwe square the blocks up, CNC programming, CNC mill, heat treating, surface grinding, wire EDM burning, and post CMM.

It's about as fun as work can be for guy who was a "lego kid."

Looks like some hydraulic something or other. Reminds me of when I take a hydraulic orbit motor apart and I never get all those holes lined up right again when I put it back together

It's a stamping die. That one is pretty small. About 10,000 pounds. Some of our dies weigh up to 59,000 pounds. The four poles at the corners are guide pins with a slip fit. They keep everything lined up. Most of the processes in that die have a tolerance of about .002".

It's pretty fun and there is a lot of skill and knowledge involved in making it all work together to produce parts. Probably a lot like those old smoker restores that you do.

Also, there are two halves there. One is the "punch" side and one is the "button" side.

BTW......reading comprehension got me here. I just realized the OP'er said moto related things you made.
7/26/2013 9:53pm
Not really moto-related, but I had some pretty nice logo stickers made by bikegraphix.com. Great price and quality. Control panel is for my automated brewery I am building.
