KS P90 Upgrade options

Gmac98

I currently own a second hand KS p90, I bought it about 10 months ago, so it is nearly 2 years old (bought it second hand). When I first bought it, it's performance was grand, I bought a tight bore for it and its performance increased quite a bit, but I still feel it could do better. Since its 2 years old, I'm worried about how long it will last me, since it is a Chinese clone. Does anyone know any good upgrades for it to make it perform better and also increase its longevity? Any help appreciated.

If it was mine I would clean and regrease the gearbox.
New piston, short stroked. Short stroke the standard gears.
New bearings, re shim the gears.
A decent hi torque motor and a standard MOSFET to protect contacts.

If short stroking you will need a stronger spring.
I would put in a bearing spring guide and possibly replace cylinder head and piston head depending on condition.

Should of mentioned the piston would need at least 3 metal teeth to be able too short stroke.
