Pro Circuit Platinum or FMF SST pipe and Boyesen exhaust flange. Make sure your jetting is correct and consider a 50 tooth rear sprocket. Honda CRs are always jetted too rich from the factory.

After that Wiseco Pro-Lite piston.

You can also bore and/or stroke the motor too...if you want to go that far.

Besides that....piston, exhaust, sprockets, carbeurator, and all that good stuff. Also make sure you have a good air filter/air intake system to make sure the engine can breathe good.

Re: Re: 2004 cr 250 mods

As for boring the CR 250, you're limited to no more than 270 cc after boring due to the power valve. Typically a new cylinder sleeve is installed. And the cylinder must be nickasil re-plated.

BTW - The stock Honda air filter is the best there is and my second choice is Twin Air.

Thanks guys. I'm not really considering a bore kit. Just wondering if anyone had any secrets they would share. I think i'm going to get a 450. If there is anyone interested, my cr250 has v-force reeds fmf gold series pipe, shorty silencer, universal bars, fork bleeders, extra plastics, and a extra front sproket.and it's clean from top to bottom. I had just tore it down to check/grease bearings. So i cleaned the hell out of it. I'm asking $3600. Oh yeah, it's a 2004
