Sully, Thanks for the correction. I was reading km on the chart.
According to the X-300 Owner's Manual:
7.6 miles x 1,000 = 7,600 miles for valve clearance inspection.
Sully, from your description of the process of checking shims on the Ninja, I might have to change my opinion.
My experience with shims has been positive with the parallel twin in my '06 Triumph Bonneville.
Maybe that's where I remember the 12,000 mile number from.
And perhaps on the Bonneville the process was a bit easier than the Ninja....Remove the tank, remove the valve cover, and the clearance can be measured.
My old Bonneville only had 4 valves to check. The new one has eight.
To change a shim, the camshaft has to be removed......however the clearances usually don't change much.
In 25,000 miles on the Bonneville, I changed 1 shim at 12,000 miles. At 24,000 miles, the clearances were still in spec.
I didn't have to buy the whole kit of shims. The Triumph took the same shim as a Honda, so I only bought 1 shim at the Honda dealer.
Perhaps, I would change my opinion about screw type valve adjusters, if
the ones on my RX3 would not change every time I check them.
On my TW 200 and DR 650, the screw adjusters work fine, and the clearances only change minimally.
I think it is a matter of a difference in metallurgy between the RX3 and the other bikes....that may be a discussion for another thread.
