Great aftermarket screw
Replaced this screw on my keihin carb. Fit fine and is SOOOO much easier to adjust while on the trail than the stock screw. Only minor complaint is that I'm fairly sure it is a little too loose and vibrates slowly out of place. Could just be my retaining spring though. Otherwise awesome replacement. Would do it over again.

Great, just didn’t work for my bike
It was a good quality tool, it just didn’t fit the KDX220 As advertised. It is too long and runs into the fuel port, so it can’t be fully installed. Wish it would have worked because it looks awesome.

Excellent Upgrade
No regrets after installing on my XCW. Much easier idle adjustment whether your carb tuning or out on the trail.

Horrible
I had a completely perfect operating 2 Stroke carb. Then I went and installed this and its companion idle adjuster screw. Bike ran horrible and I had taken extra measures to make sure I understood where my stock settings were before installing. After two rides I was finally able to get 60-70% of my pre-install performance back. Yanked them out and installed the stock parts. Ten minutes in the driveway and I was back to 90% pre install performance. Liked the idea, loved the look but hatted the performance.

Limited value over stock idle screw
For my carb (Mikuni) still need a screwdriver to turn the idle adjustment due to full line routing.
