Any Feedback on Eric Gorr's Porting & 265/285 Kit for YZ 250

[vetyz47]

Just wanted to see if any of you can offer feedback on the YZ 265/285 kit. I am trying to level the playing field outdoors with the 4-strokes, but don't know if I should just get the porting done or proceed with the big-bore as well. I do NOT want to hurt the 'rideability' of the motor. Any observations would be welcome.....The last motor Eric ported for me was very impressive... :)

I rode a big bore YZ 250 (2002) done by Eric.

If my bike had the new generation engine I would go for it. The power was very impressive.

I had Eric build a 2003 kx 265 for me about 8 months ago and love it. Motor is strong as dog breath and the rideability is there. Highly recomend it.
