Ok cool, that's what I thought but I wasn't sure if the head would lift up high enough to clear the studs. Thanks

I bought one, looks exactly the same than the original, same needle roller bearing, and the finishing standard very high.
I pay 99,95 $ (plus packing to spain), I will replace the nylon one next year (the installed one is still ok).
Do anyone already run the engine with Liska Racing unit on ?, if so any diferences during installation, noise....
Cheers

Yes, I've installed one in my motor, and put about 10,000 miles on it so far. When first installed, you will hear some chain noise, which should quiet down in the first 50 miles or so. After that, you will hear a little bit of noise from the bearing in the center of the gear. I hope this helps.

And, yes mine is working. Especially useful if you actually ride the bike.
The factory option being a lot cheaper if the bike is used only once in a while
