The frame looks good Mike! Almost there. Just some paint and it is ready to race!

Methinks the frame in the picture is a work in progress and a few more tubes will be added, I hope.

You bet. That was just tacked to get me fitted into the right position. Top tubes and cross braces being added tomorrow. After 3 tries (and 3 wood mock-ups) we finally got me into a good position.  I'll be looking above the front tire and below the lower fork tree so getting the angle of my back was critical  (I've had a few vertebrae fused together in my neck and can't tilt my head as back far as normal).

So, here's the plan..........
Motor is a built Kawasaki KX100 dirt bike engine hopefully making about 30hp at the wheel.
Weight should be 125-ish. (325 lbs raceweight.)
Frontal area will be slightly smaller than the famed Buddfab streamliner. Height at top of helmet is just shy of 32"
Textbook aeros (and a few more tricks  :evil:)
Frame is air pressurized to supply an auto-shifter. No foot controls (rear brake is hand lever actuated).
I've got sprockets to take it to 145+ (on paper, anyhow  :roll:)
Nothing will be overlooked or left to chance.

To put this in perspective, the 50cc Buddfab had 20hp and race weight was well over 600lbs. They used up 1/8 mile just getting the clutch out and still ran 96mph over the first mile and 116 at the 2 mile.

Goal is 140 (wish I could run on the long course!)

I'll try to keep up on this as I think it's going to be fun.

Critiques and suggestions are always welcome!

BuddFab had 3 square feet of frontal area ... coefficient of drag was extraordinarily low ... the driver/rider had to cock his shoulders as the frame was too narrow to lay down in square.   A lot to engineer.

She's a roller!
I'll be locating the footpegs tomorrow. There's a possibility that I may be able to touch my toes together behind the rear wheel. Depends on how close my crotch is to the front of the tire. That would do wonders for the tail aeros!

Top pic shows bungs to be used to mount footpegs behind tire. I'll be almost able to touch my toes together while straddling the rear tire. Only time in my life I wished I was more bow-legged.  :-D

Bottom pic shows the "crotch stopping post" now famous amongst my friends and subject of numerous snide remarks. Actually, the tail section will wrap around it and it won't be visible.
