Big bore Resleeve for a predator 500. I've done many big bores for Raptors with a straight sleeve. Pretty cut and dry those are. This however has a step in the outside of the sleeve which had its own issue to learn.

This is a 1974 MX360 cylinder that is built for racing. I did a light port with polishing as it had production marks as you can see in the first few photo. The object is to increase airflow by giving the air flat surfaces to flow against. It's bad enough to make air bend but it makes it worse with bumps and ridges in the ports. Even took down every transfer so the sleeve was even with the aluminum. 7th pic shows those dimples. Porting has a lot to do with increasing airflow and polishing make the air flow without obstacles. Using Killer Carbide Burs to get it done.
