300ex rev box

What exactly would a rev box do to the performance on my 300ex?

Anyone?

it will give you +1000 rpms, doesnt really do all that much, only if you have some serious motor work, its like putting a computer chip into a chevy cobalt

Well it made an immediate 5 seconds a lap faster on a MX track for my kid, your gears become longer, so if you come out of a corner with another 300, you will pull in front of him before he can change up, other than a high compression piston, it would be the second thing i would put on a Honda300

call curtis sparks. i put the 380 kit and had my head done and man it brought the bike to life. i had to run and 15/33 gear witch equaled 70+ mph. i built this back in 03 and it is long gone but still i hear my friends still talking about how impressive it was. my buddy built a 440 and i did the 380 and he said he felt like he got ripped and i got twice the bang for the buck. i guess a little to much talking on my part but if the 450s werent out i would deffinitly build another it ran with any 400 or 440 and i was 185lbs. hell i might still put another 380 together lol just for the fun of it. lol all kidding aside it is a good mod just remember that if curtis spark mods it there will be no rev limiter so over rev.
