The complexity issue is another problem, I would rather work on a broke down warrior than a newer liquid cooled machine that happened to break down. I had the motor completely torn down in less than two hours the first time I did so. You could rebuild a warrior if a bore isn't required while at a campsite in the boonies no problem. As for frame issues I doubt if the frame will bend under nos, I drilled a tree with the front right arm hard enough to break my wrist on impact, barely a tweak in the frame. It only had a slight twist, but I replaced it anyway since I was too lazy to just straighten it. Suzuki has taken the lead for bent frames on the older z400's, there isn't much room left for error here... ;D The metallic paint was better on the 02' frames anyway. Basically you want to stick to any machine you really like, that's what it comes down to. I kept my warrior just because I like the buggy look. I might just upgrade the plastics to the newer maier ones though, but I would have to find a way to fit them on the IMS tank. My plastics have gotten there ass kicked, and there is only a limited number of times you can resand them.
As for nos you can squeeze 10 seconds on 0.8lbs doing a 100hp shot, so basically us on a quad doing just a 10hp shot will give us 100 seconds on 0.8lbs of nos. That means you will get about 300 seconds of boosting on the 2.5lb tank they supply in the kits. I don't know about anyone else but it doesn't take me long to top out on just motor, that means you'll get a **** ton of drag races in on one tank. Starting in second will give you one hell of a launch, and you'll start to boost right in third or fourth gear. With nos you'll rev up much quicker in those high gears, and have a insane amount of torque added. You'll be able to at least go up hills another gear higher or two while boosting. Even on the boondockers video you'll see the banshees doing over 70 mph clocked up steep ass sand dunes, and the liquid kits hit much harder and give a much stronger boost than the foggers. The best part of nos is it costs less than 10 bucks to fill the tank and you'll have a whole trip of drag races complete on one or two tanks. As for reliability under boost, you just have to watch the clutch and basically keep her lubed with synthetic, you'll also want to run a moderate compression piston (the break down of nos is dependent on compression) and a race cam (keeps cylinder pressure a bit more comfy). As for bore keep it near stock or a moderate stroker kit with the connecting rod. As for fuel requirements you'll need to plumb a separate line or use a duel petcock, the stocker won't supply that much fuel. For a setup as mentioned you'll run premium gas with octane booster on a D9EA plug, the extra octane only needs to be there for boosting though. Nos needs a little extra usually to prevent any detonation. Octane requirements are strictly based on cylinder pressures though, if your above 190psi you'll need race fuel. A 10.25, 10.5, or 10.75 to one piston will land you right in between more than likely, and the race cam makes the 10.75 require a little less octane, landing you at about 98 octane on stock ignition timing. As for overheating on nos it is highly doubted, the nos adds a strong cooling effect just like expanding liquid nitrogen, giving you even more hp with the same heat output as the basic motor running. Not too many people realize that since more power usually means more heat, but not in this case.
