I'm getting a Garmin Nuvi 710 (and a Givi GPS case) for my bike so needed some power. I bought the socket and wires off Ebay for a fiver and I have a relay switch being delivered in the next few days. My intention is to run the wires straight from the battery, with the relay switch coming off...
If it's a 2004 model then it will have 98ps. As has been said, the lower powered model didn't come out until 2007. The easiest way to make sure it is an FZ6 rather than an FZ600 is to see if has underseat exhausts.
I'm 19 and just coming up to a years riding. Did my CBT on a Honda Lead 100 and then have been riding a Yamaha YBR125 since. I passed my test last September and pick up my new bike on Tuesday. It's a 2006 faired FZ6.
