The 1/2 shift fork on both the 5 and 6 speed has a real habit of having the roll pin walk out. Issues from this can range from missing gears to engaging two gears at once, which can be catastrophic to say the least!
We loctite the pins in to help prevent this. The available 6 speed billet forks also help eliminate this because of reduced flex in the fork itself.
You can see the 1/2 shift fork roll pin has nearly fallen out and the fork has moved up and down on the rail, causing missing gears.
