Thank you! I feel Honored that anyone would even compair my bike to Ringo's.

Perfect!
Thanks! Drilling rotors is very time consuming and boring but its totally worth it!

I love your bike! the progress is great.
Can I ask to see what drill bits you are using that make the little bevel on the hole? and where to get them. And how long do they last drilling hardened steel like that? I have been wanting to drill some lightening holes in some of my parts as well. Also any tips on laying out the holes so they wind up being symmetrical? thanks so much keep up the awesome work.

Sure Its an 80 degree countersinking bit. You can get them at most tool stores. I ordered this one on-line. Mcmaster carr has them. The metal used on the rotor doesn't even phase these things. I have literally chamfered a thousand holes with that drill. The key is using the right cutting speed lots of lube and patience. As far as a patter I don't use one. Here is the method I use. My mill, indexing table and my handy angular spacing chart. Its so nice once you get setup and decide how many hole you want for every 360 degrees you just look at the chart and start drilling.

great stuff! I think I might actually have one of those bits in my dads old tool box and never realized what it was for. I wasnt sure if you had an all in one bit that drilled and countersunk similar to the wood bits available.
I been wanting to get a small mill for some time now. I have a large powerful drill press, I might just find a rotary indexing table for it for now.
Okay so on your chart there it looks like you drilled 18 holes so you would be drilling a hole at 20* 40* 60* etc? I think is how I am reading that.
Thanks for the reply I love the fabrication end of building bikes/cars usually even more than the end result.

Yup, 18 is what I used. 18 and 36 are the easiest because they fall on either 10 or 20 degrees. So you don't really even need the chart. The only tricky part is laying out the offset and spacing of the hole for the wave pattern. You don't want to get to the last hole and have it land half on and half off your rotor. If that happens you will kick yourself.
Re: 78 kz400 cafe build ROLLER!!!!!
She is a roller as of tonight! I got my freshly drilled rotor on and front wheel mounted. I took some pictures of it resting on the kickstand. I will be moving from the basement to the garage for the final stage of this build. I also ordered my speedometer (sort of) tonight. Forward thrust will be measured via airspeed. I am working on a pitot tube for the airspeed indicator.

Looks truly spectacular man...one of the best red frame cafe builds I've seen, usually they just seem forced. This my friend, this looks fantastic...
Can't wait for completion and to here that exhaust!

Not that it would matter much to me if it was my bike, but it's hard to believe that an airspeed indicator measures low speeds accurately enough. I mean, if you are riding in a 35mph speed zone, heading into 15-25mph winds, what would the gauge read, and would you alter your speed accordingly? I would also think that riding behind a tractor-trailer in that vacuum (yes, I know that you have to get too close to it, but you get desperate in inclement weather sometimes) would throw off the gauge. In our ridiculous modern age, 5mph can be the difference between a having a fun ride, and getting a $150 ticket. Having said all of that, I have ridden (and driven) by tach alone in/on a few different vehicles, which can't be 100% accurate either, so I'm a hypocrite, haha. These are just ponderings. I think it's a pretty cool idea, and I hope it works out for you.
This gauge was made for an ultra-lite and is known for great slow speed accuracy, so It should be fairly close. Heck, the stock speedo was way off when compaired to my gps so I'm not to worried. If i'm drafting a tractor trailer than I'll just cross my fingers that he gets the ticket. ;D This bike is not going to be my daily rider either. I just thought it would be cool and different than the "tach only" setups I have seen. I 'll let you know how it works.

This came in the mail today! I got a trail lech tach/hour meter to count revs. I will use the airspeed gauge for mph and a red Flashing LED for oil pressure warning and a green Led for a nutral light. I am still working on my design/layout for the dash. I want to keep it tight and light.

I thinking about where to put it.
