[QUOTE="Lissa, post: 578045, member: 30656"] cr250enduro, are you planning to compete in the ECEA series? I compete in the ECEA Enduro circuit. I did own a '00 CR250 and did a few minor mods to increase what bottom-end hit it had. A flywheel weight does not add bottom-end power, it just helps with stalling at low RPM's and smooths out the power delivery. First thing, though, I would have your suspension dialed in and/or revalved for off-road use. Stock valving and springs will most likely pogo you until your hammered. For the motor, resin reeds are good for promoting more torque, like Boyeson's Torque reeds. If the final gearing is stock, add a two tooth larger back sprocket to bring the hit lower in the gears. For off-road legality, purchase a FMF Q' series/ spark arrestor of some sort. If you have a few extra bucks to spend, purchase a FMF Fatty or Gnarly pipe. You'll also want to get a pipe guard. Make sure your machine is jetted properly and that your top-end (piston+rings) is fresh before you start competing. A worn top-end is a great loss of performance. Besides, some ECEA enduros or Hare Scrambles will extremly tax your motor and the rest of the bike, so make sure its a 100% before you get to the starting line. Sometimes it could be a very, very long push out of the woods. Make sure all of your wheel, shock, linkage, and steering head bearings are tight, too. Water proof your bike by routing two carb vent hose into the airbox to prevent bogging in a mudhole. Also check your airbox to make sure its seams are tight. See you at the Enduro's. [/QUOTE]
