I don't hae hardly any knowledge on running nitro on sportbikes so any info would be appreciated. (ex. whats needed to run it, gains, losses) I have also heard that you can tell if a bike has nitro on it by the way it sounds... whats the difference in the sound.

thanks

Um I can tell you this. If you don't have any knowledge of nitromethane stay the fuck away from it unless you like buying and rebuilding alot of motors. Even if you know alot about nitromethane it is still really hard to set up right and you will still burn down several motors before you get it right. Even when you think you have it right you will still take out a motor ocasionally.
You can't just dump it in and go. You will need alot of work to your fuel system and then have to get it all mapped correctly.

Nitromethane is not a fuel, it's an explosive. It just so happens that some lunatics can get a motor to stay in one piece long enough to call it a "race". http://www.gixxer.com/forums/images/graemlins/wink.gif Like badass said - if you don't have deep pockets and/or a stack of motors to wreak carnage upon, leave the nitromethane to the pros.

Don't fuck with it man !!!!!!!!!!!!!!!!!!

friend of mine had nitro kawi kz bike. its pain to get setup and cost $$$. he had to change plugs every couple of passes and change oil every single pass as it gets contaminated with nitro. also depends on percentage that you run, but with alcohol/nitro the fuel system has to handle 2-3 times its stock capacities. its not for average guy. so above recommendation are correct for modern sportibkes. plus it cant stay in fuel systems and needs to be flushed out. very nasty stuff

Not to mention that the stuff costs like what? $25-$30/gallon?

Thanks guys, I know some people that run it, but I did not want to go and get help with out a basic knowledge. I just thought it would be an alternative to a turbo. I guess I can just bore and stroke the motor and spray a little gas.?? I am confused, but I know I dont' really want a turbo on my bike. Thanks again. I did not know much about the whole nitro thing but I figured, "hell everyone had to start somewhere."

ok - you said "spray" as in NITROus-oxide...

...which is completely a different animal from NITROmethane.

...when people say "nitro cars" or "nitro bikes" they generally mean nitro-methane which is not very user-friendly.

but "nitro" has come to mean lots of different things to different people.

If you're talking about nitrous-oxide, that's realtively easy to set up (compared to setting up a motor to burn nitromethane as a fuel or fuel-addative).

What are you asking about?

Nitrous oxikde and nitro methane are two completly different things. Unless you have a water injection system set up to spray nitro methane. oooops. I won't discuss that.

Nitrous is a quick cheap bang for the buck. Best bang for the buck you can get for drag racing is a stock bike with nitrous. Nitrous is much easier to set up for. No problem running it on a stock bike. You just need to know the limits of what the motor can handle and not get greedy and excede that unless you don't mind blowing motors. Also I can not stress to get it dynoed to check the A/F ratio before using it on the strip/street.

I was asking about running nitromethane, btu when you guys said how bad of and idea it was; I just figured I needed to build a stroker and put nitrous oxide on it.
I wanted nitromethane because there is a bike that I want to beat REALLY bad and I figured that would be the best way without everyone saying "ohh well thats got a turdbo on it". If I set it up as an injection system, I would still have to change oil every race right? But, cold I disarm the injection kit and srteet ride it. I dont want to go through all that trouble for a race only bike.

I need to be in the low 5 sec range on a streetable bike, I will have a slick and sidewinder, but those are easy to exchange.

We will assume you mean low 5 sec range in the 1/8?

That's haulin' *ss for a street-tire/no wheelie-bar bike!

If its the 1/8 40 shot with a arm and a slick can get you there. A friend of mine runs 8.8 in 1/4

yes, I meant in the 1/8 mile I live in a small town the closest 1/4 mile is in memphis.

It requires mechalnical fuel injection to flow enough fuel. On top of that, the engine cases are not near strong enough to keep your crankshaft from rolling around on the dragstrip.

what kind of bike are you running?

low 5's is huge numbers for a true street bike, my bike that runs 8.3's in the 1/4 runs 5.20's in hte 1/8th, thats with a slick and bar, you will need a 7 sec 1/4 mile capable motor in order to have a chance of running low 5's in a street chassis. hope you got about $15-20k to spend....
