O.K. for all those that said the cables were too tight...you are the winners!!! So simple now that I know...I feel like a dork, but it was a learning experience!! For all future Rizoma owners follow these simple guidelines.
1) Loosen the cables first before you do anything.
2) unscrew the tensioner just below the handlebars and undo the cables from the stock throttle tube, it's a snap.
3) Remove throttle tube.
4) Put Rizoma grip on and reconnect cables.
5) Tighten tensioner to your liking.
6) Ride like HELL!!
Cheers, and thanks for all the info
P.S. Anyone want to come to my house and swap the front and rear suspension with me? Gixxer forks and a ZX 10 shock out back. My wife's a mean cook!!
