Be careful to use L-shaped air valves on rear wheel

[balkoger]

I want to check the balance of rear wheel, because when I check the CVT transmission on center stand, the rear wheel have up-down movement between 2000-5000 rpm.
When take off the rear wheel, I found a very interesting sign on crank case.
The L shaped air valve cup on rear wheel rubbing the crank case.
I never heard that while riding a bike and I check tire presure maybe twice last year however the air cap also appeared rubbing sign.
That air valve faced to left, because muffler on the right side, which is very hot sometimes 
Need a little adjustment, turn by hand, use some spray on until the air valve have enough clearance.

I hope nobody have same situation...

When I change rear tire on my 2019 Xtown 300i---at 10,000 miles or so (I hope) plan to switch L shaped valve with short rubber, high speed valve stem from Honda parts.  Simply don't like the vulnerable curved ones!

Whoa...10,000 on a 300's rear?
My Forza 300 must have been about the same weight and HP....and 6,000 was a good mileage.
Just thinking...

Sure plan on 10,000 miles, why not?  Riding a lot on long trips replacing scooter tires can be a problem as most dealers (including Honda and Suzuki whose scooters use same size) choice of replacement for me is Michelin Power Pure SC.  They wear round, got 11,000 miles on rear on SilverWing....about same on Burgman 400.

I use the high performance 'L' type ones from Bridgeport.

Will never have this issue.
