Much better than trying some wrench or home-made adjuster; I only needed to drill a small hole in it to put a wire tag through it so I could find it in my pack and when I drop it on the ground ... being small and black makes it easy to otherwise lose ... great performance, vital to me tuning my KTM power valve spring
Silly it doesn't come with the bike, once it's set how I like I will probably never use it again. I still think KTM and Husky should just use a standard sized torx or hex key. Why have one item that isn't standard. Anyway, it's good.
Handy tool to adjust power valve on the trail. I drilled small hole in handle for a breakaway lanyard that I can wear under my jersey like a necklace. I can pull it out and adjust power valve in about 20 seconds (if you like to play with different settings)
How cool is it to be able to adjust the power valve out in the woods. Play around with changing the opening of the power valve at varying rpm's. I adjusted it to rip. Then found it to be twitchy on single track. So I turned the valve in one and a half or so turns and it was back to mellow at low rpm.
JD Jetting has snap shots of the dyno power curves of all three springs and the valve turned to different points on their website. Interesting.
Machine this part was bought for: 2014 KTM 250 XC-W (E-Start)
