I'd like to see an area for longevity on the Chinese motors. I'd like to have mine around for several more years.
I like to think of my motor as 'refined stock'. I don't do upgrades for performance, more for reliability and to replace known problem parts. Like plugs, wires bolts etc. I'm ordering a K&N style filter, so that maybe a bit of a hop up but I think, better filtration is better for the motor.Here is my maintenance schedule that I follow (Sometimes )

P.S. I keep my motor completely stock
