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... :)
