I have tried to contact Annibus (ElCheapo) about getting the rotors drilled for my '77 CB750F, but have not heard back.

Does anyone know of another outlet for this?

Have you tried getting a new rotor that has been drilled and slotted already off the bay?

Find SPEEDRACER741 on the forum.
he did a top notch drill/chamfer/resurface job on mine.

HellFishTat · « **Reply #3 on:** September 01, 2009, 11:30:36 am »

Thanks Flybox1. I sent him a message. I'll make sure to let him know you pointed me in his direction.

Chris Schumann in Portland, OR did mine...he did a really good job...had them resurfaced too

you can email him here: speedracer741_@hotmail.com

here's how mine turned out (custom 40 pattern)

is it for looks or does it really help??

I dont think it does anything because the rotor isnt vented. Or does it?

SKTP · « **Reply #7 on:** September 01, 2009, 03:49:04 pm »

I am praying that it stops the shrieking banshees that cry out everytime I brake...

garagedoreen · « **Reply #8 on:** September 01, 2009, 03:55:14 pm »

the cross drilled wholes are to exhaust the brake pad gas between the pad and the rotor, so the pad has better contact with the rotor. And if its not vented then the brake pad gas doesnt have any where to go anyways.

either way it looks cool.

Im probibly going to do it on my bike too.

You answered your own question?

They don't need to be vented, like a slot would do, the holes simply store the gas until the rotor turns past the pads, then the gas escapes. Debris and water as well.

They also make it lighter which goes to unsprung weight.

THen there's that coolness issue too.

unsprung weight and coolness are all I'm looking to gain!

I hope you picked up on the sarcasam. Coolness, at this point in my life is a distant memory.

Unsprung weight on the other hand...the poor old girl's got enough extra sprung weight, so anything I can do to help.

Nope missed it, thought you were serious. I was.

At this point in my life, I'm looking for all the "cool"ness I can get.

Weight loss at the hub of a wheel is different from weight loss else where.

Meh, that looks close to the patern I drew up and have pdf's available for in the main website to download for DIY'ers..
Did I mention that I made several types of patterns so one could drill them themselves and save some cash for more NOS parts...Here ya go.
Say thankyou jason.

Now go save some money and buy NOS parts for your bike, it will thank you later for it.

Man I gotta get mine finished...

How do you drill them yourself? Drillpress or hand drill?

Don't think it matters as long as you drill slow and don't bend them. You don't want to muck up a rotor, or any braking component.

And use a quality bit... NO HARBOR FREIGHT.

Spikeybike · « **Reply #21 on:** September 02, 2009, 10:25:01 am »

it definitely matters ... use a drill press !!! it'll never happen by hand .... you would give up long before finishing

Qingdao · « **Reply #22 on:** September 02, 2009, 10:28:04 am »

French curves would help; along with other artsy stuff. But you could get by with a good ruler.

IDK I have a half horse Craftsman drill from the 50s that would put some modern presses to shame.

Spikeybike · « **Reply #23 on:** September 02, 2009, 10:41:57 am »

ok i suppose it's "possible" but it would take FOREVER ... not to mention, you'd probably have to stop a bunch of times to let the rotor cool down
