Put this on my 77 KTM Foxi with a stock 504. Fits ok, but is tight at the neck so may need filing. Sticks out to the side a little more than original so it taps on the pedal crank. Also does not have the restricting washer at the neck so you'll have to rejet. I had to go from a 50 to a 62. But its the right size, cheap, and has held up well.
Fits but needs a retune
