Oh, it's too late to be joking. Folks have too much invested in stem direction now. I think they need to be turned to the left to offset the weight of the exhaust.

Both pointed right for easier access when on the sidestand. I never looked at the location of the balance weights, but I did notice a lot of them this time around. Definitely no balance issues, though. I don't run far into triple digit speeds, but I do get there and she's still smooth.

The OEM weights on my rear tire was 2 oz.  when I had cyclegear balance it last time they put 2 oz of stick ons. Which is 8 little chicklet size squares.  Last week when I balanced it it took 6  1/4 oz weights. I split them 3 on each side of the rim.

I static balanced mine when I installed it, and the rear took over 4 ounces as I recall.  After the tire was half gone, it developed a up & down vibration, that started around 110mph and got worse as speed increased.  As the tire wore, the starting speed for the vibration became lower and lower.  I knew I'd be replacing the tires before long, so I didn't worry about it, since I don't go that fast very often.   ::)

I don't have any trouble with the stock valve stems, so it wasn't a big deal for to remove it and go back to stock.  I prefer less balancing weight over tire inflation convenience.  Especially since I carry my own air pump.

Agreed.  And the toilet paper must go over the top of the roll, unless you own a cat.   ::)

Now you've done it, this thread might have to go the arena.

I removed my 90 degree valve stem. I couldn't keep the tire balanced with it on the wheel. Of course it was only a problem once the speedometer moved into triple digit range, so it might be acceptable to most.  I guess the phrase YMMV is applicable here.   ;)

I haven't went for this solution since I had a prob on the first bike I tried the 90 degree stems on.

Tires wouldn't balance out.  Old stems back on and it was zero issues. 

That wasn't on my C14 though, old Honda bike.  If the bike would've had KiPass, the wheels would've balanced out with the bent stems (and more than likely without weights!)  ;D

Yep.  Tires would have magically mounted themselves and self balanced with KIPASS.
