400EX REV BOX?
#2
curtis sparks high rev CDI $115
it will give you about 1000 more rpm
with that you might want to get the ignition adavance key $15
it will advance the timing by 6 degrees

do not get the sparks rev box. that will make the bike hard to start in cold weather. get the MILD curve gt thunder rev box. he has an aggressive curve box as well. while the bike will still start in winter with this box it won't want to idle until it gets warm.

big gun says it adds 3 horsepower. www.gtthunder.com is the site. he may not even show the rev boxes on his site though. you will want to call or email him.
