Steady garage 143cc bore kit review
Well i installed the 143cc bore kit on my z125 and decided to port my cylinder head aswell and i must say its well worth it.
install was very simple and nothing to crazy. one thing you will notice is the intake and exhaust ports are stupid small and the intake port is smaller then the intake manifold so opening them up helps allot. if you have porting experience its well worth the time to do and makes the bike way more crisp with a stock valve job.
just figured id let everyone know
what i have done to my z
