Open Belt Drive
The pros out weight the cons in my eyes...:2thumbs:
Pros:
1) No more primary cover to pull
2) No more drive chain adjustments
3) No more primary oil changes
4) Easier/quicker clutch removals
5) Sounds great
6) It's just bad azz!!!

:2thumbs:
Cons:
1) If you're still living in the 70's you might get your bell bottoms caught in the belt (But you can buy a forward guard with the kit to prevent that) so the only con is a little more money.
2) If you have big azz feet like me, the back of your boot may rub on the forward pully and create grind marks on the back of your left boot. I don't care because my heel rests on top of my foot peg so it happens every once in a while. If you have extended controls you wont have this issue. I'm short statured.
