It finally lives! Here is a short vid of the first startup. Running really rich, but at least it's running! Unfortunately the iPhone sound quality doesn't do it any justice, but you get the idea.. Let me know if you can't view it via Facebook and I'll try to get it up on YouTube...

I would also say KZ, this caliper is off a '78 KZ650 and it is the same as the one on my '76 KZ1000. The bleed nipple is in a different place but the caliper mostly looks the same as the one you have.

Good idea, one with a 12mm wide rotor instead of an 8mm and a 4mm together. Pretty sure Honda CB750 has a 12mm rotor that looks very similar, may be worth a look. Johngoodenoug I installed my one the other day but did not use the sloppy rotor provided. See how it goes!

Hi Okie I have the specs written down somewhere, when I find it I'll let you know Pretty sure it is Shell #1 or very similar. The 101° lobe separation could be a giveaway...

Hey mate the bike is now in the Sunshine Coast, but that won't stop me from catching up for a beer next time I'm up!

Hi Paul, I made up the patten out of a blank alternator cover that I machined up a few years ago. I just sat it straight in the box and didn't bother mounting it on a board because we made so few. Great to know that there is a patten maker on here, someone to bounce ideas off. Do you have...

Heiden tuning May stock them, that's where I got my one about 12 months ago when I couldn't get one at mikes. I originally purchased one from mikes 7or & years ago and the quality was much better back then. The Heiden on has a pair of rotors sandwiched in together to make up the extra thickness...

Nearly ready to send, just need to screw some ply board to the outside

If they are 80mm LA Sleeves the OD will be smaller than 91mm, and the lower end should drop straight into the crankcases without any machining. I am pretty sure 750 sleeves don't break throughout the wall of the cylinder casting when installed, but that can also depend on the original casting...

I had the same thing happen on my 850. Well similar anyway, I was running a copper gasket so it leaked instead of blew out. It leaked back down the stud holes and into the crankcase and was throwing oil out the breather like crazy! The machinist bored out the jugs (the aluminum bit with the...

To get a real 1 off look I decided to cast some side covers and oil filter covers. Heating the metal in a propane fired furnace that I made from a beer keg. My Old man does a bit of backyard foundry work. Still learning but getting some good results! Making the sand mould Pouring...

It's gunna have to run dry! The clutch shaft is solid, there is no oil feed to any of the gears or the clutch. For the few hours of work this thing will get, it will probably be ok

Almost there...!

Cam is now finished, the sprocket is a modified stock item. It has had the sides machined off it, slotted holes machined in for adjustment, and degree marks machined in for easy 'dialing in'

Measured each installed height of each valve spring and made seats to suit, there are slight variations left to right and big variation inlet to exhaust. Zach Jones at RD Spring was a great help- he made me up some custom spring seats to fit over my valve guides because they are different to...

Nearly ready to sit the head on, just waiting for valve springs

Yep that's the ones! There is many websites that sell them, expect to pay between $21 - $30 each, for me in Australia I had to find the one with the cheapest intl shipping so I ended up paying $24 each plus shipping

I can't take credit for that one unfortunately, I wish I was that good on the welder! I got one of my friends to do it for me.

The replacement rocker arm set seems to be an ok product, a little rough around the edges but better than any worn out set. Just make sure you bin the valve adjusting screws! This is one I bought about 18 months ago and only just recently opened it up to use it. The oil squirter hole has been...
