Polishing Ports

[mrmatt]

I took my jugs off to smooth and polish the exhaust ports, but I have a few questions before I start.

Will 80 grit rolls provide a smooth enough finish or should I try to find abrasive rolls with a finer grit?

Should I do anything on the intake side? I've heard that a rough finish on the intake side helps to keep the fuel suspended, but should I clean up some of the rough casting lines anyway?

Thanks

Matt 80 grit maye be to fine for some on the intakes. I used cutter tip in my die grinder .

Start with 80 on the exhaust side and work up to 400 than use a felt pad and mirror the finish exhaust. Knife edge the transfer bridges too.

If you follow the port walls and just clean up you will feel a difference.

Just be careful if you are new to it. Go slow and ENjoy time with your Shee & it Will hualass.

On stock jugs the intake is actually painted with a smooth glossy paint, and cleaning them up as you rough up the surfaces with #40 will work good.

On the exhuast port after you go as high as you can with the grit then use aluminuim polish on the a felt attachment for a mirror finish.

Thanks for the input. I couldn't find any felt tips locally so I am going to order some from Eastwood tomorrow. I'll try to post some pics when I'm done.
