Well, I have the collar, but button fell off the fork guard at some point. I searched E-Bay and didn't come up with anything reasonable. Saw a few knock off holeshot devices I may try, but this one worked OK when I had the button attached. It was actually from a 2007 RMZ-450, but fit my 2005 KX-250 well enough to work as advertised. Figured I'd reach out on here before I made a final decision. Thanks!
