Cylinder hone help PGO Star 50 cylinder based off 84 HONDA

Post by 87PGOSTAR50GUY »

Hey I need advice on honing I feel 220 short tip 3 teeth stone hones too light

Looking for a slightly deeper ra between 15-20 ra stock rings.

I looked at ball hone none = 40mm

Closest is a nylon steel brush about 13/32

I want to do it perfect

Jugs based off 84 nb50 specs with -.1 on the piston height


NB 50 84 40mm x 39.3


Yamaha/ minarelli piston spec 40mm x 49.2 which represents the negative one.


Cast cyl cast rings


What's the best grit rate for a 3 stone hone in compriaon to ball hone.


Quick in and out break the glaze. Stone hones catch the port timing sides which is why i prefer ball.
