Default next good mod for the 400ex??

i am wanting a little more power. currently my engine consists of a 406 at 10.8:1 compression, stage 2 hotcam, uni filter, fcr 39mm, sparks x-6 pipe.

i am not sure what to do next. i know i need an aftermarket ignition box. i hit that stock rev limit too easily. what do you recommend doing next?? i really don't care if i loose some low end power. i need power in 3rd, 4th, and 5th gear.

i currently run 15/36 gearing

that K&N won't add any more noticable power over any other filter. i have the lid modded so it is getting air. however, the K&N's do flow more air, but they also flow more dust and the gains won't be noticable.

I would swap out to a K&N with outerwear, and a Alba Action CDI Rev Box. If that isn't enough, then I would go back into the motor, and up the cc to a 440. The 440 is basically the next big step you have in where your build is at, and where you can take it.

i will be getting an igntion box. however, i had the sparks and didn't like it. i think i will be getting an adjustable one. i was thinking msd or dyna.

i mainly drag race and am never on a track. so, i rather spend the cash on the motor instead of on shocks that won't do much benefit for my style of riding besides a little better launch and a smoother ride. i am mainly on flat land when dragging.
