Blasphemer!!! 
Yeh, that's all I could come up with, too. It just sucks cause of the range of rpms on a bike....anywhere from idle to, in this case, 11k-ish rpms. So, juicin outta the hole ain't gonna hit like a nice Mack truck like someone wished it would at 6k rpms.. 
You crazy fool.....and you got one of these bikes, too.
Because without a nitrous controller when you press the button you are spraying a set amount of nitrous regardless or RPM. For arguement say you are spraying 1# per minute. ( A 100 shot on a V-8 uses 1# per minute, a 25 shot on a 4-cyl. bike will use a lot less) Now at 4000 RPMs each cylinder is consuming 1/1000th of a pound per revolution, at 8000RPMs each cylinder only has to consume 1/2000th of a pound per revolution. If you spray at 8000 vs 4000 you only have half as much nitrous in the cylinder, thereby giving you lower cylinder temps.
The less nitrous in a cylinder the less power but the cylinder does not run as hot and you reduce your risk of explosion.

blah... you knew what i meant.
this n2o idea has lead some of these guys to having 3 stages for a total of 150hp on ls1's and you know what happen? they blew the head gasket just like the guy using a 1 stage 150 shot.
i don't like it at all...never have.

If you are blowing LS1 head gaskets on a 150 shot then there are other problems. The LSX series of motors LOVE nitrous. Big Bad Buick was spraying at least 150 on his stock LT1 for a long time with no bad problems.

[QUOTE=LogicalRetard;3371215]Why is that? Just because more rpms = more opportunity to burn? Just wondering dood.

no problem, nitrous is a commonly misunderstood power adder.
the initial hit, and torque spike attibuted to it, puts a lot of unwanted stress on the rotating assembly. its why people say to retard your timing, because nitrous burns hotter and quicker, thus the piston will have alot more load on it before it actually reaches TDC. you can spray a 25shot at 3000rpm, and see a 60rwtq increase, wherease that same shot at say 9000rpm, would only net you a 20rwtq increase. basically, the constant to the equation is the flow of nitrous(given bottle pressure stays the same) ...its all dicated by the solenoid and jetting.
basically you have an engine consuming ~61 cubic inches of air per rotation, for ease of this, we'll just say .035cfm per roation. at 3000rpm(x .035cfm) the ZX10 is pulling in 105cfm, while the nitrous is encompassing 45 cubic feet of that. now at 9000rpm the motor is taking in 315cfm, but still only 45cfm of that is nitrous.
