Current mods:
sprocket: 15T front, 39T rear
front: oil level up to 130mm (or air level to be exact). fresh 10W oil. (slight nose dive, I think I could go 115mm as most ppl recommend)
rear: ZX600c shock, 10w, zero psi.
repair and maintenance done:
swingarm lube, steering head bearing and race replaced, tires taken off and replaced (don't know how to balance correctly though). Carb cleaned (worst experience ever)
