Well maintained, garage kept. Fresh oil and brake fluid. Previous owner dropped it on the left side, damage to tank, headlight and rear seat handle (see pictures). This has to be one of the best learner/commuter bikes ever made. I get 50mpg of mixed driving and is extremely comfortable to ride...

Well to answer my own question it seems my bike has a normal level of vibes. Just bought a 2017 FZ10 and has only slightly less vibes. I'll still do the valve check eventually.

Didn't say it in my first post but did the engine mounts and exhaust previously with no change. I'll check the main stay but don't think its loose. The previous owner did lay the bike down at maybe 20mhp on the left side. Just cosmetic damage. After you mention all that makes me wonder if that...

Makes sense, thanks for explaining it. Given the milage I have it will be interesting to see the results.

You would have more experience, I just don't understand how metal in the valve train can increase in size to cause a tighter gap. I figured metal would compress/wear out over time and cause a larger gap and lower lift.

Wouldn't a higher vacuum mean it's getting more air at idle. It's sucking in more air. When going to 4k rpms the values were higher. Idle screw works just fine. Can move 900-2100rpms if I want, have it sitting right at 1260-1300. Last time I had the air box off there was no visual issue with the...

I have the carb tune, all cylinders were at 22cm at idle.

I checked tb sync and they were within 4mm of each other at idle and 4k rpms. Got them to within 2mm but no noticable difference. Will check valves hopefully in the next few weeks.

Second the tb sync hose.

I'm not following you on the "butterflies are open". Are you saying the TB doesn't open until after 4k rpms? I'll give 4k a try and see if anything changes. The engine is definitely not running rough. It is very smooth in power delivery, and the power is just fine at the top end, no looping idle...

Why would it not matter to sync above 4k rpms? I did 6k because it is closer to where I'll be on the highway. I do plan on checking the valves, just wasn't sure if there was anything else to look into. FWIW I pulled the header and the tops of the valves all looked good/uniform. Can't remember...

That link is what I meant by checking the plug wires. Wheels were balanced with new tires about 1k miles ago, no change. Could valve clearance really cause vibs? Was hoping there might be other low hanging fruit to try.

I'm trying to figure out if I am trying to fix something that just can't get any better on my 04. Currently at 6k rpms and up I am getting what I would consider unreasonably high levels or handlebar and seat vibes (I can live with the seat vibs). At 9k the stock mirrors are useless since they...

Man, and I thought the giveaway was that you reached 145mph. Everyone knows we can't go more than 137mph.

Have you checked to make sure there is no vacuum leaks?
