I was surprised by the oil change intervals.
The main bearings are shells (not balls or roller). Con rod big ends are needle bearings.
Seems to be very low maintenance for a bike. Valve adjustments are shims so probably not much chance of doing that in my garage, but if they want too much I can tear it down and measure then order the proper shims. Did that on my 73 Alfa GTV in 1982, drove it another 100 k miles and valves were still in spec. On the Alfa you had to pull both cams to get the buckets out then replace the shims on top of the valve stems. Measured before taking the cams out. I wonder if the cylinders are wet liners like the Alfa.
