What is the banshee max rpm on the engine?

 

2 strokes will rev for ever, it all depends on the pipe. the pipe is what cuts power at certin RPMS

 

Stock I dunno, prolly like 9000-10000. Modded, you CAN run like 13000+ but theres really no point to it. Motor wont live very long that way and you wont really be gaining anything so its better to build a motor that dosent need to rev that high. My motor goes to about 11 then the power falls off, I think thats about what people normally shoot for.

BTW, there are some more restrictions on revs such as:
Weight of the crank (on my bike 10500-11000 is the max, past that crank will progessively vibrate to pieces because of its weight. Wish I could drop in a shee crank [img]i/expressions/face-icon-small-sad.gif[/img] ).
height of the exhaust port
ignition (points on mine can float, no idea where a banshee ignition maxes out but probably alot higher than mine, but still somewhere).
compression ratio (alot of compression holds a motor back at high revs)
and probably some more im forgetting or dont know.

 

I don't think you can even turn 9000 with stock pipes. Aftermarket pipes, porting, compression, and timing are the limit after that. CPI pipes peak at about 9700. Somewhere between there and 10,500 is the peak for most banshees. After peak you lose power quickly.
