yea, I'll try to get ahold of him. I had to jump ship on the fabricator I had been using for this project and now im totally up creek without a paddle.

So i made more progress today i made my measurements for the cut to move up the "Y" piece, so check it!!!

I realized that i needed to cut out A LOT!

But after a lot of trimming slowly and precisely I finally got a fit that was like a glove!

And what do ya know !!

So this weeks challenge is going to be bending the square tubing for the engine cradle, i need to make some more mounts obviously, but i smell premix in my soon future!

Listen ... like dad in mom ... (French-speaking) Sorry ...
Good idea, doing the edges V before the weld.
équiliber also pin at the top of Y, square

So stoked!!!!! Sponsors are really coming through on this build for us! Thanks so much Mika Metals, T.M. Designs, DNA Wheels, DT1 Filters, CTO goggles, Tamer holeshot devices, and everyone else that has helped get it this far.. Final fabrication and welding starts next wednesday!!!!!

Stay tuned!

Going to look gash with the original engine mounting holes still on the "Y". Plus you have an extra weld and heat cycle doing it that way. Will you be heat treating the frame once it has been welded?

LundMx · « **Reply #34 on:** March 28, 2013, 01:43:05 PM »

The holes were removed from the y piece and smoothed over.. Yes the frame will be re-heattreated after fabrication, my friend who ownes a powdercoat company is going to do it for me. Does anyone know how hot to treat it at and for how long?

brooksie · « **Reply #35 on:** March 28, 2013, 02:44:39 PM »

That's a a good idea re heat treating. I also have a friend who does powder coating. It's the one thing that worries me. Now that the engine is in and things going back on, the frame rails look rather small. Not very confidence inspiring. I'm kinda wishing I'd just bought a used SH bike sometimes. Although frustrating at times, it is rewarding over coming some of the problems...

Looking good!

those radii on the rails turned out great! i got a shop to do mine that had a HUGE $$$ bender and mine's got more creasing than that. nice fitment there.

LundMx · « **Reply #39 on:** April 04, 2013, 04:29:48 AM »

this is the bender we used : http://www.jd2.com/p-42-model-4-bender.aspx its about a $1200.00 bender

don46 · « **Reply #40 on:** April 04, 2013, 05:21:20 AM »

I have the JD2 model 3 bender, it does a nice job, the benders are the cheat part, the dies are $300+ depending on the size. I used the 1" radius tubing, it ended up looking factory.

LundMx · « **Reply #41 on:** April 05, 2013, 03:37:36 AM »

So more progress made once again! check it out!

weld time!

TIME TO MOUNT THIS MOTOR!

TIME TO MOUNT THE FRONT OF THE MOTOR

LIKE A GLOVE!

AND TONIGHT WE START ON THE HEADSTAY AND PIPE!

sandblaster · « **Reply #42 on:** April 05, 2013, 03:43:01 AM »

Excellent progress.
Great job!

LundMx · « **Reply #43 on:** April 05, 2013, 04:53:56 AM »

Ran into a snag, and a big one at that! the kx250f radiators are too long and hit the "Y" piece... need shorter rads.. any suggestions on where to start?
