Update-
Not much has happened lately, using my buddies garage for the project so the last few weeks hes needed it. Exhaust is done and mounted but really not happy with it. Sticks up above the rear fender, needs some pipe cut down and a mount made. With that said, its not a high priority and can be done when ever.
For those that might be trying to run the G2 2stroke perch and PWK39 (or other PWKs ?) I ended up using a Motion pro T3 #10-3000. Threads into the carb cap and the perch and solves the WOT if the cable gets pulled. This cable is for KTM 2strokes and is 5inches longer then there stock cable, and is about factory length for the two Kx500 cables I have here.
Just need a day to put it all back together, mount the two perches and prey like hell it starts up lol. Getting excited, should have been done by now. Hopefully get to ride it a bit then I will tear it all down for powder coating this winter and take care of any details that need to be addressed.
