Re: 1976 KZ400 Cafe Transformation (First Motorcycle)
So I recently drilled my rotors, what do you guys think? I used a 5 speed drill press I got from Harbor Freight for $42. It worked pretty well once I used my Ryobi Cobalt drill bits. I had tried some cheap TiN drill bits from HF at first but they were kind of cheap and I think my speed was too high because they kept dulling instantly. Once I switched to the cobalt bits it was smooth sailing.

Re: 1976 KZ400 Cafe Transformation (First Motorcycle) -Just Drilled My Rotor
I have not slightly chamfered the holes yet so they are a little sharp. But what do you guys recommend for chamfering holes. I was thinking of just using a bigger bit and taking of a tiny amount of material. Is there a better way? I really don't want to have to buy special chamfering bits.

I like the look when the holes decrease in size as they spiral out, it helps the eye to follow the spiral pattern instead of picking up triangles or trapazoids or whatever. Build is looking good though.

i would recommend lightly sanding the holes with something like 80-120 grit sandpaper because you want them sharp so they work better but you don't want burs on the holes
if that doesn't work though grab something like a 1/2" drill and lightly by hand twist it in the hole and that will debur it pretty well

I would suggest buying a counter sink bit to chamfer the hole. Just buy the cheapest one when it comes to this as you will only need to hold it at each hold for a second and it should last for the duration of the project. A $5 will be more than adequate.

If you already have a bigger bit, that should work just fine. You just need to debur the hole, not chamfer it. Like DoubleL3 said, spin the bit with your hand and a little sandpaper and it should be good to go.

Well I do have a countersink bit, so I think when I get back to Chicago in a few weeks all give that a try. Also what do you guys do to clean up the surface of the rotor. Its not that uneven, but there is some uneven wear that could use some smoothing out. Could I just sand it smooth?

Dumb question:
How do you get a bike on those rear race stands by yourself? It seems like a 2 man job to me.
I kept my center stand, it's nice for oil changes, tightening chain slack, etc.

not a dumb question if you havent seen it done. As you can see its more or less an L shape, so when putting the bike up the vertical line of the "L" is actually horizontal, then you pull down on the handle on the horizontal part (which is actually vertical now) and through leverage it lifts the bike. And since Im a visual learner myself I gathered a few pics to illustrate:
in this position youd roll it under the swing arm and line it up then pull down on the handle
and in this position the bike would be lifted

Re: 1976 KZ400 Cafe Transformation (First Motorcycle) -Rebuilt the Engine
So I finished rebuilding the engine. I painted the crankcases, head, valve cover, and breather cover with Duplicolor Cast Aluminum engine enamel. The block is painted with gloss black Duplicolor engine enamel.
Here is the crankcase with block installed
Pistons in block
Head Gasket installed
Rebuilt head
Head installed
Camshaft in place
Valve cover installed

Re: 1976 KZ400 Cafe Transformation (First Motorcycle) -Rebuilt Engine
So I have decided to build a fiberglass cafe seat for my 1976 KZ400. I am going to create a plug then a mold and finally my seat. Currently I am in the plug stage. Here are some pictures of the progress I have made.
I started with a wooden plug and then begin to cover the plug in body filler to get the shape I was really looking for.
Here you can see the layers of wood I built the seat hump out of.
Mostly covered in the first coat of body filler
Sanding the first coat
Second coat of body filler
Second coat sanded
The plug went though a series of smaller body filler coats to remove any pinholes or problems with the hump shape.
Primered plug:

Yea the plug took like four days because I ended up reworking it so many times and because I was working out in a cold garage. I actually just created the mold and will upload pics of that soon
