After yesterday's oil flush + oil change (at 1015km), I went for tuning today.
Mechanic admired the cleanliness of the engine inside.
Topped up battery water.
Cleaned carb and its jets and attached a new seal at engine end (between the black plastic separator and carb)
Had me buy new plastic housing of air filter and installed a new filter.
Spark plug was ok, just adjusted timing and tappet clearance.
Mobil oil on drive chain.
His charges = US $ 2 only.
He told me to always use Qalco 20W50 API SJ ($3 for 0.7 liter) engine oil. I had used 20W60 SF for $3.5
Had new rear view mirrors installed = $2
He told me to get oil change at 600-800km always.
A good day for motorcycle.

I was thinking of doing that here in California, but I seldom drive my bike in the heat of the day so I think 10W-40 is perfectly fine for summer, but then 90 is pretty hot for here. If I were driving in 100+ weather I think 20W-50 would be a better choice.
