awesome. did you changing the gearing at all to adapt to racing?

That is pretty epic imo. If I had a welder and a few years of experience I would have fun like that too. Very nice.

i dont think it looks at all ugly.

ergos look racey and awesome too

The return hose on the rad actually sings way right of the front wheel (just looks like there is clearance issues in the photos. The output hose is another story it was close on the orange bike but it's very close on this one. I have it pulled back with a few zip ties but think I can get a bit more clearance by trimming the "fat" from the hoses.

I only used a welder to tack a few things into place. Everything I added is brazed together. I picked up a cheep ($45) OXY/MAP set-up at the hardware store and figured out how to do it my self to do it wail working on the gas tank. I was going through the mini Oxy tanks like hot cakes and at $10 a pop it adds up fast. I actually had an r20 bottle (20 cu/ft) of oxy and another for accedline that had all the hoses but was missing a torch (I would have used this set-up but the cheapest I could find a torch was $150). I picked up an pipe to hose connector at kragen and just removed the hose from the old oxy pick-up and attached it to the new bottle. Now it cost me $25 to top the tank and it's been going strong for the past 3 weeks (I used 4 bottles of the other stuff in the period of a week). Not only dose it last longer and cost less to refill you can put out more oxy and thus use more map gas and thus get a hotter bigger flame. I really doubt that the other bottles could even dream of brazing the thick cross brace to the frame.

Reason the tank is where it is, I started with it mounted to the stock tab just under the top tripple plate. That put the seat way too far forward, with it set-up that way I was sitting where the tank is now. Felt really weird so the tank got pushed back. Best part is the front of the seat pan butts up to the rear of the tank as it and if/when I swap over for a fiberglass or carbon magnum tank it will fit perfectly all the way up to the triples.

Gearing right now is set at 40-17. The pipe hits so late that I am worries about being left in the dust on the starting line and really having trubble coming out of the corners. Want to go through the bike piece by piece and get a seat that is actually attached before I see how fast she still is on the top end.

Looks like it's going to be a busy week...

why is it that you make the bikes i drool after??!?! i thought the orange one wasent going to be beat but THIS TAKES IT! fuck yea man Pin It To Win It! that thing should be a best once you get er' all tuned for your likes

Well it's official not only is she alive but she's powerful as hell!

Huge thanks to Leo Vince for both sponsoring the 77 race team and also allowing us access to there state of the art dyno and there awesome tuner Manny. We took 5 bikes over to the east bay for a fun afternoon of dyno running, jetting and beer drinking.

We ran three other bikes before mine and by that point the O2 probe that goes into the pipe was saturated with oil and giving false reading. Initial air/fuel looked lean as shit but then upon upjetting I lost all power and the air / fuel was still off the meter.

Back down to a 110 main and did a few more pulls. This is what she was able to do.

At the wheel hp

Current gearing is 17/40. I'll be bringing a host of gears to the track to find out what works best. Also not shown is the max rpm the motor hit which is 14k, huge thanks to MotoMaticMopeds for building that sweet monster of a pipe.

There are a whole lot of spinning bits in the gear box.

At the Sf rally the rigid was running 18/32 (or 36 I forget). Either way a good bit higher that it is now.

Someday ill have enough money to take advantage of my own oxy acet torch to make a kickass frame. (People dont know that braising is super easy :P)

Overlap the base metal in your brazed joints for strength
