This project was a little more complicated than the handlebar risers. It was 2 separate details that I bolted together.

Does it rob any power when you use it? My crf had to be wide open on the exhaust to get the full benefit from the power up jetting and other adjustments. Then it pulled like a tractor all the time, over or under geared, hardly any lug at all even 2 gears high. Fan the clutch a tad, break it loose and when it hooked hang on tight... You know the deal. Nothing like my YZ 2 stroke, better not ever be 2 gears high on it.

Bob,

It does restrict the flow a bit, but you need the spark arrestor screen to ride off road so the loss of power is worth not getting a ticket:biggrin:

Really good job Kevin, have you made anything else for the yz 250F ?
 
Thanks Chuck,

That’s the only thing I’ve made for my friends YZ250F. It was a good learning experience for sure :))
