Hi All, grin
It's not much yet, but enclosed is the beginning of my project.
ENGINE-Jawa Model 870, 625cc, 1 cylinder, 4 valve OHC, 12.8:1 comp., 6 speed, counterbalanced, liquid cooled, dry sump. (currently the only one in the U.S.) Approx. 80HP

FRAME-replica British Seeley style roadrace frame ( www.framecrafters.net ), but with 38 degree steering angle, and + 4" swingarm.

FORKS-brand new take offs from 2008 Kawasaki ZZR600

WHEELS-mag wheels from Aprilia RS250

Roughly guessing, the bike should weigh in at under 300 lbs.

Will find someone lighter than a 250+lb guy in bib overalls to do the riding.
650 A-AG
650 APS

As with all things mechanical, completion date depends on $$$.
However, it should be returning home as a roller in the very near future.

See ya this fall at BUB either way.

Sounds and looking good Drew - I love the 300lbs with the power that Jawa should put out. Did I hear correct, you are making a down draft manifold for it ?  Please keep the pics coming as it progresses.

Hey Drew, I raced a Jawa for a number of years...



This one was 500cc on methanol. I had two that were identical. Also had a couple of Weslakes. The Jawas were awesome Speedway bikes. Can't wait to see your "special built" Jawa on the salt. I hope it doesn't run total loss oiling like ours  grin

Best of luck!

"Dry sump"   I run an old total loss (oil that is, not the motor) Weslake.  Does that motor run plain bearings?  Good luck with the build.

Hi Guys,
    Please let me answer a few questions with one note.
First, nice speedway picture Rocky. You should try a few laps on a  new laydown short stroke Jawa.
Much lighter, and you're on the pipe & sideways before you know it.
I too own 2 Weslakes, 1 Godden, 2 Jawa laydowns, and a GM laydown.

HOWEVER, the Jawa engine I'm using in the landspeed bike is NOT originally designed for speedway,
but for roadracing and sidecar motocross.

Dry sump means it has an internal oil pump and external oil tank.
Kind of like the bikes I've made my living with i.e.-Hogley-Davidstone
See the pictures in my first post and notice there are no fins.
All 500 speedway engines are air cooled, and this 625 is liquid cooled.

See Ya

Hi All,
    I received a couple new shots of my frame progress;
so I thought I'd pass them along.
All that is left for www.framecrafters.net to do is mount rear shocks,
and fabricate an aluminum fuel tank.
Then I get the roller back home to do on all remaining work.

I am very pleased with the bike so far, and suggest framecrafters to others.

See ya grin

I really like seeing this project.

Its also good to see that you also take full advantage of having a "shop dog"

Most of the "ole timers" wont understand this but here is my version of a Jawas I knew as a kid... grin



When I saw you were building a Jawa B-ville these are the only thing I ever knew a Jawa to be~

Hi Everyone,
    I just got back from Framecrafters www.framecrafters.net  in Illinois, and picking up my rolling chassis. They did a fine job on the whole thing. The fuel tank looks large, but volumewise does not hold as much as appears. There is a tall arched tunnel section underneath for clearance of the downdraft carb and velocity stack that will protrude into it considerably.
Now comes all the rest of the fun building. I will proceed as money allows, but at least now the bike is at home in MY shop, and I can begin machining things such as various mounting brackets and rear sets, etc.
See Ya
Drew

The picture is of the crew that built my chassis-Right to Left:
Randy Illg, Carson Illg, Jason
All great fabricators and welders.

Are you going to put shocks on it or run rigid?
