I'm not able to view the images in Woody's post, can anyone clue me in to what I'm doing wrong. I have right clicked on the tiny picture box I do see, cut and pasted the URL from the pic in a new browser window, and still no go! Says cannot find server. Help!!

Sorry Chris, this is due to my server being down

I'll get it fixed in the next 24 hours or so and let you know when it's up.

I adjusted my fuel screw is all, but I was a tad rich on the top end, so your results may vary.

I finally took the screen outa mine...have yet to ride it yet. I cant wait to feel the results.

[Woody_393]

Let us know what you think, or if you can even tell a difference.

[smithers]

I havent even fired it up..I bet it sounds a lil different also

[Woody_393]

You can hear it sucking better.

Got to ride for a bit for the first time since I did that and put on a Uni air filter. (Been doing tons of landscaping) And I have to say there is a big low end to mid-range gain in power. And yes more noise to boot. Im very pleased with the results.

Hey would this be a bad idea if rode at the dunes. Also anybody do it to there yz 250f how is the difference.

[Woody_393]

You should be fine at the dunes. It might make your air filter get dirty faster, but that's it.

The original mod was passed on by FFR. Who was doing them on YZ450F's. So it should work fine on a YZ250F too.

Sweet thanks, Woody
