I tightened my chain some time last week and 'eye balled it' on the slack. I ran through about a tank of gas and had apprehensions about the slack. I got home last night and measured it and realized I was about 1/2" shy of where it should be (it was at 1"). I adjusted it and I'm good to go.

One observation: With the chain that tight, the vibrations were VERY noticable through the entire bike in the 5000-6000 range. It was really quite strange.

Random thought: The reviews of the FZ by the 'experts' :pisson says the vibrations are really bad. I wonder if whoever set the bike up for them didn't have enough slack in the chain and that's where the vibrations were coming from.

It's possible, but they may have just gotten a bike that vibrates a lot. Mine vibrates a lot more than the average FZ6 (from what I've read, and from one test ride on another FZ6). If I wrote a review of my bike, I'd mention bad vibration, too.

I would have written abotu the vibrations when I first got the bike, but the more I ride it, the less I notice it. I kind of like the vibration because when I hit 5000, I get a tickle, and I know where I am engine-wise instead of having to stare at the tach.

I think you just nailed the problem.

In my first 1000 km I had the typical vibration at 6000 rpm. Of course, the chain is believed to gradually stretch a bit during the breakin period. I am now at 4500 km, and the vibration has completely vanished. I measured my chain slack last weekend and noted it to have increased 1/4" since the original setup. So, I think the increased slack (now at 1,1/4") has solved the vibs.

I didn't put this all together in my mind until just now reading your thread.

You're the man!

I noticed the 5K vibes really lessened after the 600 mile service and disappear almost entirely after 1000 miles. I bet the chain was either too loose or tight and the 600 mile service sorted that out.

Sort of the same thing with my V-Strom - it had some minor vibes through the handlebar at all RPM's and after the 600 mile service, those vibes are now totally gone.
