I've seen a lot of black engines with the first few rows of fins on the head polished on the edges. Any suggestions on how to do it?

Darn, with so many daily riders it's hard to decide which one to jump on next.

Sand and polish before I paint or after? I was thinking of doing all the polishing before I paint and then either mask the fins first using 1/8" tape or wipe off the black on the edges using acetone after.

I used a flat file to square off the fins. You can use a sanding block with 250-400 to finish it off. Then paint the engine. After paint is dry sand the top coat of paint off.
inprobably finished with a very fine 800 grit.
same goes for the cam covers except they won't need as much filing.Last edited by posplayr; 09-28-2014, 02:25 PM.Comment

I have also been known to use a Roloc wheel, but VERY carefully, it will easily get away from you.

For squaring off fins I use 220 sandpaper on a hard rubber sanding block. And after paint I use sandpaper 400-1000 grit. The block does make it easier. I have also used a palm sander to speed up the process, but that only works when you have the motor out of the frame.Comment

I sanded and polished my fins on my Yamaha V Star 1100 Classic and love the look, also been sanding and polishing part sof my restoration/bobber project (82 GS1100GL). I used 120, 220, 320 and 400 sandpaper then Mother's polish. it will turn black and wipe off with clean cloths then afterwards use a nice microfiber cloth and it will shine.Comment
