Hard to believe its been almost a month since last update. But we've been staying busy. Last time, Joe had a test drive. After about 8 miles, he pulled in and the rear hub was smoking hot. But odd, it didn't really seem to affect the rolling resistance. Anyway, New bearings are on the menu, and some diagnosis. It was so long ago I can't remember if I(we) installed these or had someone else do it. AND, we put 180 miles on it with no heating issues. Damn I hate these mystery problems. Anyway, enjoy the pics. I'm going to bed. (Bought a 9 pc bearing puller/slide hammer outfit)

Well; I'm gong to start with an update as of today and work my way back.  We've had several shop days, with little details to accomplish. But today I flexed my otherwise atrophied muscles and got the 2 wheels loaded into the car.  Then drove them up to Ducati (what a nice shop) for a new set of Avon Road Riders. The guys remembered who I was (the guy with the purple CB750) Somebody from the shop or parts dept came out every 20 min or so to give me an update, like (or better than) they do at the hospital.

Now I don't have to feel self conscious sending Joe out on  a high speed run and fearing that the 10 year old tires would fly apart!

More soon.   ;D

Awesome Ron  8)  Couple more shake downs and we can get it to the Dyno.

Sadly my 750 will take a lot longer to get mobile  >:(  Refinishing my workshop is taking forever.

AS mentioned, I'm going from recent to not so recent:
New Avon tyres mounted up and balanced.

Here's my tool for holding the axle still whilst removing the axle nut:

We have to remove 1 caliper to get the front wheel off, and let out all the air, and English it just right. Luckily we don't have to break the hydraulic line, jus bungee the caliper up out of the way, and stuff a dbl fold of cardboard in the pads to keep them from closing.
We modified the truing stand by moving the stantions together. There wer 2 holes for a slight adjustment. But that's simply not enough to keep the wheel steady. So Joe drilled aother set.

The purple nuts are cool. But slightly taller than stock, so they look like they're not on all the way. Don't know if I can stand for that.

Job 1 will be to get the brakes working. It took a while but we discovered that when the wheel was at certain parts of its up and down arc, the brake actuation rod came into contact with my ubertrick centerstand stay. So, we need to move the over the the left side and give the rod room to breath.  That means new muffler mounts both left and right. I've got some other ideas, both functional and blingful. More later.

Pic of purple titanium cprocket nuts with nulock. Should have been in the last post.


JOKER brake stay and actuator rod. I've got several joker pieces already (valve caps and oil pressure gauge/and attache) along with Frankensteins clear plastic points cover, and Saldana exhaust brackets with holes,continues the hole/dimple motif:





Polished aluminum. Needs some chrome.   ;)

Thanks for the posts Joe! I'm liking those pipes. The peak of the "blips" registered about 5000 rpm. I'll bet they really sing above 6000. I'm a  member of the hard break in crowd. This engine only has about 15 miles on it. I'm ready to let someone (You) take it out and thrash it.

we decided to eliminate a variable and move the centerstand stop to the left side at least for now. Don't want anything interfering with the brake controls. For a scab job it worked out pretty well. Too bad the picture doesn't show as well.


With that done, and a final of several finals bolt tightening and etc. Joe took it for a spin.





After a nerve wracking (my nerves, waiting for Joe to get back)  25 miles, he pulled back into the shop. No leaks! No smoke (well a little out of the breather)

Yay!

I’m afraid to say I can’t comment...I only rode the hot rod about 10 miles last year before taking it off road to fix starter clutch issue and then having to take the front end apart to replace steering bearing.  And the I decided to upgrade all the electrics....and then I got sucked into gutting and remodeling part of house

I’m really hoping to get it all back together and running in the next 2 months.  Just not enough time in the day

I'm scheduled for a dyno run on the 17th, but a work obligation may get in the way. We're getting closer anyway.
Maybe some duplicates in this batch as it spans the last 4-6 weeks:
Joker Machine Brake rod and brake stay



The end sticks into the hole on the head of the axle, keeps it from spinning when tightening axle.

Thin stainless steel washers, Taller titanium sprocket nuts , finished in purple, with nylok inserts;

Modified pit posse truing/balancing stand

New tires. I didn't wear out a set, they just got too old to use  :(


Had the muffler hangers reworked, no pics.
Carry on!

Thanks, the speed holes are particularly unique, useful, etc.

I'll get the whole bracket chromed over the window for added aerodynamics.  ;D
