Thanks Ken. This will help immensely when I have to rebuild eventually. I have 2 of these and found both to be a little quirky about upshifting to 5th. If I just shifted like the other gears, it wouldn't engage, so I had to firmly shift and it felt like that extra push would engage 5th with an extra click. It looks like the inside cover mod may be necessary. Overall, I'm happy with them. They're really nice in the twisties here on the East Coast where you operate around 3K and up RPM's. Just pick a gear and keep it in that range.
