I had no idea how much shit there was that you could do to a lil CRF 100!!! I just assumed no one really bothered making many parts for it, cuz it was so small, but I found some crazy shit out there. I found a 145cc Bore kit, as well as an light-weight aluminum frame with mounts to accomodate CR85 Expert suspension components, all kinds of crazy shit. Oooooh the ideas....... its just good to know that when I get bored of it, there will still be some life left in it with a few mods.:LolLolLolLol:

well...i might not pull out the chainsaw. but the trail will be made accessable.

and if the quad doesnt do it. theres access to it from a sandpit about 500 feet down the road!

Dude, I would've been there yesterday if it didn't rain! I can't wait to get that shit cleared out so we can tear it up!

Back to the original topic: CRF Mods:
BBR makes a RevBox, that removes the 9800rpm rev-limiter, and is a bolt-in replacement for the ignition. Its less than $50!!! Yippee!!! Apparently, the CRF 100 motor can pull all the way to 14,000 rpms!!!! But, power drops like a rock after 12,000, but the word is the most power it makes is right at 10,000 rpms, 200 more then I can get to now! So, $50 and I get to reach peak power of the motor (while stock), and get an extra 2200 usable rpms! Definitely gotta get in on this and the BBR exhaust. I also found some airbox vents that are $8.50/set of 6. You just drill 1" holes in the airbox, and these foam (washable) vents clip in place to let a ton more air into the engine. Anybody know about K&N air filters for CRF 100? Are they decent? I know they work well on cars, but not sure on bikes, but hell they're only $35.53, so maybe I'll just get it and find out. So, I think that's the first stage for me:

BBR Exhaust
BBR Rev Box
K&N Air Filter
Airbox Vents

That should get me a little more power, more usable rpms and also a meaner sound and look, I can't wait! :rock:

rain? pussies...lol

hey miller if i were you I'd spend the money on some decent gear and replace stuff as it breaks....maybe another set of rims and some street tires so you can do some parking lot sessions...i am sure it is fast enough for now...

Street tires will definitely be coming at some point...
Exhaust- eh, the stock one looks and sounds sooo weak and is pretty restrictive, so I gotta replace it at some point. The RevBox is cheap and I would like to rev a lil higher, so that ones cool. The vents I'm not so sure about, it seems a little sketchy to me. K&N would be kind of cool, cuz you don't have to replace them.
