Nice alternative to the stock screw.

Comments On Feb 03, 2015:Works great, just wish it was a little shorter as clearance is tight.

First one did not work for 2008 YZ250F

Comments On Jan 14, 2015:I was excited about the low price and many positive reviews so I thought it would be a simple swap. Unfortunately it did not work like the stock screw. Stock screw was at two turns out to reach high idle. This screw would jump straight to high idle less than a quarter turn out. I took it in and out three times and even swapped the o-ring, washer and spring with the stock one to see if that would make a difference. Nothing worked. I finally measured the Tusk screw with my digital caliper and found it to be smaller in diameter than the stock one on all three levels of the stem. It is only like .05mm smaller but I guess that makes a difference. I know that can make a big difference in valve shims so I assume it is the same with fuel screws. Rocky Mountain is sending me another one for free to check out. If it does not work I will send them both back. Rocky Mountain is awesome!

Additional Comments On Feb 02, 2015:The new screw is working fine for now. Thanks Rocky Mountain for sending me another!!!
