Done these mods , much better but air screw needs tweeking . Can be great at beginning of ride and then needs tweeking a few hrs later . A jd air adjustment screw/knob would help this issue as it would be easy to reach with your hand
@@matt-gz4qd notching the front (reed side) of the slide will make the pilot circuit more efficient. By notching the front of the slide, it will allow the pilot jet to provide more fuel, so you will find that you will need to reduce the pilot jet size. Increasing the airbox side cutaway will lean the mixture from off idle to about 1/4 throttle due to the larger volume of air (and less velocity) passing under the slide.
Works great. Made a part 2 video. Since then i put another 20 hours on it works awesome. I raced at elevation 4-6k feet. Could’ve used the other needle but ran fine.
I did all those mods to my 17 xcw. I liked the JD kit better, and reinstalled it. Nice vid!
did you try bending the overflow tube to a higher spot?
