Okay I know there a lot of Honda gurus on here, so here is the question. If you could or have already had motor work on your Honda 250 smoker, what would you/did you do? What were you happy with? I have a 2002 with rad valve and Keihin Stryker with a pro circuit pipe. Not sure if I will get anything done (don't really need it but as we all know that is not the point...)

Paging CamP. CamP to the white courtesy phone please.



Cheapest upgrade is to use a 05+ base gasket on there. I think the 03/04 powervalve fits in the 02 cylinder and seals better, but I'm not totally certain on that.

Thanks Matt. I know from what I have read in here that Cam P knows his Hondas!

Just do a search on cr 250 mods on this page. There are a few good pages.

I just had mine done but it's an 07 so probably not much help. Porting and pipe helped a lot though.

Details on what porting I had done can be discussed thru pm, email, or text if you are interested. I don't know what the power is like on an 02 but the 07 had power all right in the middle. Now its nice, smooth and keeps on pulling. And it's not a big bore or anything. Kept it pretty simple and reliable.

For porting I would go to Tom Morgan. http://www.morganracingengines.com/

Oh and I found the PC pipe killed the bottom end and only marginally added to the top. If you can find an OEM pipe give it a try. Love mine.

The 05-07 base gasket is supposed to improve bottom end on the 02-04 CR250s
