Motion Pro 01-0094 Throttle Sleeve
Amazon.com: Motion Pro 01-0094 Throttle Sleeve: Automotive
This is the exact one I bought. I know it says it doesn't fit the FZ8, but trust me it does. If I were you, I'd do the throttle mod myself. It'll be cheaper than having the dealer do it and it will be a lot more rewarding. It's super easy and there is a how to on here that gives step by step instructions(w/ pics) on how to do it. Plus, if you get stuck, you can always ask for help on here.
