Yamaha left that spot for Cruizin to fit the launch control for his upcoming missile system.

I've noticed, when the bikes running and leaning on the kickstand. The oil will line up pretty closely with where it is when turned off and level.
Would I use it as the be all end all? No. But good for a quick check while letting it warm up.

When adjusting the chain or reinstalling a rear tire, the swing arm hash marks and four-pronged bole don't present the same image on each side. It depends on how much play or tolerance is taken up by that four-pronged bolt and the accuracy of those hash marks, maybe?

I double check with a caliper ruler.

My speedometer is 6% too optimistic.
 
 
I'm curious how you found this. I've been testing mine this past week. I use the speed view app. I've had between 5 and 8 satellites tracking me. My speedometer is off by almost exactly 1mph.
 
I checked at 15,30,40,60,80,90. All speeds were of by approximately .75-1.15 MPH.
 
Also, all street radar speed checkers show almost the exact same thing.

I used my Garmin GPS. And compared it with some iPhone app. The phone and gps were both the same and speedo was 6% faster.

Strange. My first bike, ninja 250, almost exactly 10% off. Second bike was 6% off, sv650sa. And now three different sources all say my FZ is 1mph off.
 
But on the fz others get 6%, some get 2/3%. Could it really be that variable?

Normally speedos read around 5% or so fast...
Actually, once upon a time, that number was 10%. You could count on an indicated 70mph only being 63 or so in reality. My 3 BMWs (including the "Brown Stain", as it was affectionately called, in my avatar)  were all like this.   
Not so much anymore. These digital speedos are frequently off by a fixed speed more than by percent. My Aprilia is optimistic by 1 mile in 100 whether by distance or by speed (as per Garmin - looking away from the road at triple digit speeds is not advisable, so do at your own risk) . I think my FZ is more like 2 mph fast wherever you want to look.
 
I'm guessing the speedo sensor for this bike reads the front sprocket ( or countershaft ) so as you have rear tire wear, you'll travel less far for every rotation of whatever is seen. Changing a sprocket size should also throw some confusion into the mix.

If you lived in a place that didn't require the headlight to be on at all times there would be a switch to turn off the headlight.
You're right, I found a picture of an old yamaha with the same thing. But you can see an imprint with on/off too. I I guess that on some markets the FZ07 has an extra switch to turn off the headlight.

I've discovered if a "big f..ing hammer" doesn't fix it, then it's probably an electrical problem..............LOL

Yeah, but are those Canadian miles?  You gotta factor in the conversion rate.

Haha, funny. But you're right.
We have kilometres and we are metric too, so there is that. It involved quite a bit of math but it finally came up with 6%, see:

As I posted in another thread, my speedo seems spot on. I used a Garmin app (Viago, no longer available) on my phone, which has speed reading. The two agree within 1 mph ( strangely, I find hard to look at the phone while going 65 mph on the bike :) ).
I have bought a combination usb ports (2) and a cigarette lighter plug and mounted it on the left handlebar. I power it using the power port (fused at 2amps) under the left side. It should be good for chrging phone and/or standalone gps.
If I remember, I'll switch the speedo to km/h and the phone to km/h and see if the agreement persists. One hopes that the engineers at Yamaha can convert miles and km accurately...Apparently someone at Nasa couldn't convert Lb and Newtons few years back :(

Funny to see two speedo discussions going on at the same time but I can't merge one into the other because it will probably mess things up. My 6% remark was from a year ago. Oh well. I am pretty sure about my 6%, I measured at different speeds. I was pretty happy with that, my previous bike was even worse. Canadian bikes can't switch from km to miles for some reason.

Owner's Manual indicates to support the bike from the swing arm (using a jack on either stand if I recall correctly) for the rear wheel and to use a stand for the front wheel.
