Speaking of Torque, what are you all torquing your rear axle nut to? In the manual it says 137 ft lbs but when i got it back from the dealer after the rear tire replacement it was maybe 50? On my Vmax it is 85.

I torqued it to spec with a torque wrench. No need to second guess Yamaha manual. Sounds like your dealer was just sloppy.

I do 90-100ft.lbs on both the FZ1 and 10. I have had no ill effects on either. Torque specs for the rear axle nut on sport bikes from the other big 3 are in the 75-95ft.lb range, with similar nut size.
Putting 137ft.lbs on the axle nut isn't hard but it just does not feel right. And having been bitten once already by incorrect torque figures in the Yamaha service manuals I don't mind adding a dash of common sense to the stated values.

I have a good bar wrench and I put 135ish on there and you are right, it didn't feel right creak creak. I will probably do 100 +/- next time

I cleaned and adjusted my chain yesterday. I have a long breaker bar for removal and followed the manual tq spec. Considering the hp of the motor, I wouldn't putt any less.

Agreed, it does feel crazy tight at 137 ft.lb.
Seems like every other manufacturer with as much or higher hp/torque are all in the 75-90 ft.lb range from s1000r/rr,zx10r, gsx-r 1000, KTM SDR,Tuono.
Although even the R1 is listed the same at 137 ft.lb, and this has been discussed quite a bit on their forums.
Maybe they misprinted ft.lb and meant 137 newton meter, which would put it at ~100 ft.lb.
I would think you are more than safe at 100 ft.lb, but even if something cracks or strips at 137 ft.lb it would be a manufacturer warranty claim given that's what's stated in the manual.

While we're on the topic, anybody know what sizes are needed for the front and rear axles? No biggie, I can figure it out when I get to my first tire change.

I'm going to be doing this tomorrow and already have my wrench set to 137, if this is wrong someone needs to fix the manual ASAP and send out a bulletin if it's incorrect.

Not all tq wrenches are calibrated or created equal. I set mine to 120 because it is notorious to actually put out a little higher than what is set. No issues.
Something I've noticed on sport bikes is when you over-torque (and sometimes when you torque to spec..) you cause the axle end's flat side to dig into the axle block. Suzuki had a recall on their axle block deforming (aluminum) when you torqued the nut to spec. I've resorted to a good torque wrench and yoshimura axle blocks that capture the whole axle end in the block. First time I torqued the nut on the FZ I saw a little gap between the axle flat side and axle block.. ordered the Yosh blocks that same night.
