Please check it out and let me know what you think! I appreciate any input you have for me :)
umberto I may try the lectron in the future for the reasons you've posted. I was emailing David over there, i believe he is the vp. He was very kind and helpful, so I would like to give them business if It works out. for now, as you can see in the photos in the library attached, the oem carb fits almost flawlessly. I just wish i could stretch the rubber .375 inches on top. If anyone has tips on that, I would appreciate it. I love how I can do some metal work but when it comes to a rubber... Im just no good ;)
The kx exhaust is way huge on the yz frame. Gonna need to cut it up so I can lower it about 6 inches and remove the stinger almost completely. I may cut a short segment from the belly. Ive been doing a lot of research and it appears this would increase the top rpm, which would give me more the small 2 stroke revability which i fell in love with as a kid and still find more fun than anything. Also interested in belly exit exhaust instead of at the end of the baffle. who knows but I'm gonna have to cut that pipe up like swiss cheese here this weekend.

Looks like it's going to be one hell of a great ride when it's done. Look up pics of the 125 air boot and compare to the 250 boot. I bet the 125 air boot will reach a little farther. Take a chance on one from eBay. Even if it doesn't work, you a won't be set back much.

Break in done. I know my jetting is rich so Ill work on that tomorrow. Not sure the needle clip position, ill find out. right now it has a 170 main, 60 pilot, and air screw at 1.75 out. more smoke than I like. Jetting chart on this forum suggests 168 main and 58 pilot. My gearing is 13-40, weird i know, its just what I had. But I figured it would pull harder than it is so I know jetting must be off. Although, starting it is a 1 kick affair, unlike what the internet would like you to believe. definitely not getting a compression release yet. Im beginning to think 500's are more myth than anything else :\ "please let correct jetting cure my need for speed". I won't be happy until theres solid matter in my britches.

When I finished getting everything in, the airboot was almost perfect so I ended up not needing to change it. Thanks for this tip though, I didn't know that.
