Heres the tank, complete with the "Bat Cave" , where the sparkplug lives...

Image

A view, installed. I wanted to keep as much fuel volume as possible, and this seemed like the approach to take. I only lost a quart in volume. I think the Service Honda looses more, Scott told me his tank holds less than 2 gallons, and its a real pain in high fuel flow environments, like the dunes.

Image

Looks pretty stock, throw some mud and dust on it.... The coil wire can been seen handing back to the subframe, where the coil and CDI are mounted. Sticking them back there really opens up the front of the bike.

Bonding fiberglass to polypropelyne is supposed to be a big no-no..... Uncle Cracker says I'm going to blow myself up....

Image

I sure hope not.

I made have to return to plan "A", and have my welder complete something like this.

I kinda like what you have done. Whether it will go "BOOM" I have no clue. Why couldn't you now have a mold made so the whole thing can be done in poly?

Plan "A" would be totally cool though!!!

THE FINAL COSTS:

Before I list them, first let me explain something about how I computed it...

If my Steelie was stolen before I started this project, I would have been bummed, but another way to look at it would be to say that the bike was fully amortized.... That is to say that I had received more enjoyment from the bike, in the time I have owned it, than its real value. Its another way of expressing that I had gotten all my moneys worth out of the bike, yet still owned it..... make sense? As such, the original cost of my '97 Steelie was not factored in....

Ok, now for the costs of the conversion.....

$1100 Cost of CRF250X
$100 1" tubing
$30 Lexan for airbox spacer
$72 FMF Silencer
$16 Coil Wire
$100 Misc Items ( Muggy Rod, hoseclamps, electrical ,screws, etc..)
$500 Welding

Total: $1918

Credits for cast off parts sold:

$200 500 Forks and Shock, Swingarm ( Earth calling Troy Lewis... Come in Please!)
$50 500 PMB Kick Stand
$325 Blown up CRF250 Engine
$50 CRF Wiring Harness
$150 CRF Carb
$20 CRF Clutch Perch
$25 CRF Kicker
$15 CRF Pipe
$115 Spare CR500 Rear Wheel w/ Paddle
$80 CR500 Rear Wheel Loose
$71 500 Front Wheel
$26 CRF Rear Brake Bracket
$36 500 Rad Braces
$38 500 Front Brake
$20 CRF Shock Spring
$20 500 Rear Brake
$29 500 Skid Plate


Total: $1270

Net Cost for Conversion: $ 648.... Not too shabby.

Now, for the Bling Factor:

$400 New 18" Rear Wheel ( For Dunes)
$280 Quad Style Flexx Bars
$51 Used Front Wheel ( For Dunes )
$48 10 paddle Tire
$38 Sand Front
$10 Front Tube
$99 Fork Springs
$99 Shock Spring
$52 HandGuard Mounts
$12 Grips

Total: $1089

B-day Gift Shark Fin
B-day Gift Skid Plate
X-mas Gift Peg Lowering Kit
X-mas Gift Ironman sprocket for Dune Wheel.
Gift Coil Mount ( Thanks Danny G.!)
Gift Motor Mounts ( Thanks Shanman!)
Gift Swingarm Spacers and Bushings ( Thanks Joe!)


Grand total in Costs: $1737

What did I get? A CR500A/FX converted exactly how I wanted it. Plus bars and pegs to help it fit me, AND extra wheelsets for going to the dunes.

Granted, I did have a fair bit of luck in finding the chassis, and great friends like Shan and Graves feeding me parts... BUT... If you already own a Steelie, and can score a Gen 1 for a reasonable amount.... I think you can come up with similar numbers building your own A/F conversion.

I am at the point of reconnecting the Y. I found that the downtube is tapered and gets larger as it goes up. Did you taper the bottom of the downtube or open up the Y?

BTW You inspired me to do this. Hope mine turns out as good

That is correct. I opened up the socket with a die grinder / carbide burr. It didnt take a whole lot of material removal, but it was a little tedious..... cutting...fitting....cutting..fitting....

The down tube is pretty thick, removing material from it may be easier.

Perhaps removing some from the tube first, and then fitting the socket is the way to go?

Good luck on your build! Start a thread of your own, so we can follow along.

i ground the downtube on mine. it was fairly easy. just don't go up too high. the front of it is thicker that the rear, so i took more off the front than the rear.
