Printed off a template.
Cut it out, put a veeeeery light coat of spray glue on it and stuck it on the rotor.
Went through with a center punch and punched each hole in (near ) the center.
Got a 1/4 inch cobalt tipped drill bit
Set the drill press to 250 Rpms and added a drop of oil and away we went!
About 45 minutes later she looked like this
I then hit it with some 800 grit sandpaper on a pneumatic orbital to take all the little burrs out.
And then got it reinstalled on the bike.
Huge visual improvement, a good bit lighter, and should really help wet performance and cooling. I'm a happy camper. Overall cost: $5.46 and an hour and a half of my time.
Thanks guys.
I'm so add I can't get things done fast enough haha.
I'm antsy for my new cases to get here so I can make some real progress getting this engine rebuilt
Your rotor looks good, nice work. Once your new cases arrive, take the time to properly inspect, clean, prep, prime, paint and heat cure them, they will look great.
Where do you guys usually get gudgeon (piston pin) clips?
the cb400F is 13mm is this something i can get at autozone or do i really need to pay to ship .42 cent parts?
Oh yeah, I got tired of being covered in soda, so I took 15 min to build this to help out. It works surprisingly well. Has a shop vac hooked to the back to suck the dust out (it only does a mediocre job)
