There is a treasure trove of information here to be appreciated by all. Thank you all for sharing.
Closed course. Professional rider. Do not attempt.

Still privately owned and operated by Hayabusa owner enthusiasts. 2002, small  a/a kit, CF body

If it's in a truck or trailer, it's being stolen

Thanks for the great discussion guys! I have also been thinking about meth instead of nitrous. I suppose I could use the same injection setup as I have for nitrous. I would need to install yet another tank and electric pump. Hmm, I wonder if the intercooler tank could also serve as the methanol reservoir? Would a methanol mix hurt the aluminum tubing in the intercooler? Just thinking about saving space. I need a place to sit too.

Don:  That is a very innovative chassis,
and I'd love to know more about it. 

If the front end from a Yamaha?

If you are doing N20 wet, you might consider using alcohol as the supplemental fuel.   that is one fierce looking bike Don, it does seem to be running out of room

In the early 2000's, I ran a nitrous bike from master-tuner Wayne Pollack,
and we campaigned it for a year in the ECTA. 

We set a record at EVERY meet, and gained the ECTA #1 plate for the year.

I think we scored more points than any other vehicle before or since,
 which was mainly due to Wayne's good riding, thinking and tuning !

He designed the stock Hayabusa engine to run gasoline with
methanol for an enrichment, rather that gasoline.

The bike got four(4) people into the ECTA 200 MPH Club

He set up the stock bike but with a 200hp shot of nitrous, which
ran two (2) years on the same set of plugs...............

IF you ran straight methanol for a fuel, you would need only one(1) fuel tank.

Yes, it's better to change oil after every run - which I did with my turbo methanol bike.

Easier than changing engines.

Cheaper too ................

Good eyes Scott! Yes this is a Frankencycle. The front and back ends  are from a 1993 Yamaha GTS 1000 which has the forkless swing arm front.  That way the front of the bike can stay very low to the ground. No tall forks to try to see through. To get the steering to work like a conventional bike I had use control links and make a mount for a drag bike style handlebar. The Hayabusa engine has a all custom mounting but fits.

For what it is worth, I use Ethanol as fuel.  It gives some engine cooling, not as much as Methanol, but still can be significant.  But the big plus is it not nearly as corrosive as Methanol and you just handle it like any other oxygenated race fuel.

This is pretty original Don,
and I wish you the best of luck. 

Low means less frontal area,
which means more speed for the
same power - aero being equal.

Having the Busa means working with
 a power plant you know so very well !

Ransom certainly knows more about
Hayabusa and Nitrous than anybody else on the planet.

I have heard that some folks like the availability
and cold-start ease of E85, not to mention
 keeping the plugs working in that
cold "slurry" of alcohol and nitrous.

Your thoughts Ransom ?

Going from race fuel (gasoline types) to Ethanol based fuel (E85) is pretty straight forward.  Nitrous sure likes it and overall, from a tuning aspect, you don't have to relearn a bunch of settings. As long as the ambient temps are above 50F, it starts the same and doesn't require additional oil changes.  Add 27% to the fuel map from a non-oxgenated fuel map (eg C16) to start with and keep the timing the same.  You can keep it in the tank for awhile without worries of corrosion.  I would however recommend for racing, using Ethanol from a race fuel company for consistency.  I use Ignite Race Fuel which is actually 90% Ethanol; pump E85 summer blend is actually ~80% Ethanol.
