hello. iv got a pitsterpro z160ho. says 155z stamped on the cylinder tho. i ordered the tbw0377 piston kit. 60mm piston looks to be high comp with the dome groove top. costs $117 delivered. and the stock one is like $50 $10 shipping so about 60. so this one’s definitely pricier. and iv heard it makes them go a bit harder and nicer. just wanting some help installing the new piston taking the motor apart. and installing the piston rings. really have no clue hey.
