OMR: '76 KZ900 Restoration/Modification

that sure is a purdy tape measure ya got there!:laugh:

great thread...on the favorites list....thanks alot for each picture and how your theory is along each photo...even i'm starting to get what's happening there..takes some of the mystery out of what i may need for my head ... and i may have some questions ...before i re-assemble the 73 motor.....thanks again..peace

Glad to here everything is coming together for you.
Regarding MRE, look on the bright side. You learned a lot from this , as far as engine building goes. It really is a good thing that the piston hit the head. Just think of what would have happened it just cleared. The most important lesson I learned, was to measure EVERYTHING. As soon as u get away from stock and start your own build u have to record every measurement there is.
This is how I discovered that my professionally built motor had a poorly aligned machine surface on the block and case, resulting in #1 piston being .007” higher than #4.
Its all good bro.
We all just keep learning.

Amen to that brother....

Just a little update....

Based on Larry's advice (thanks Larry) the ideal shim clearance desired would be .04 to .06...

Received my new 2.4mm shims from Z1....
I installed the new 240's on the Intake side and swapped 235's into the exhaust side. My new measurements are as followed.

Valve Lifter Clearance:
Intake # 1 # 2 # 3 # 4
.05mm .04mm .05mm .05mm

Exhaust # 1 # 2 # 3 # 4
.05mm .05mm .05mm .05mm

For good measures, I went through the cam degreeing triple checking everything was in order... good thing I did.

My intake came out at 105.75 degrees, no adjustments where required for the lobe center of my .365 cams are 105.

But my exhaust side was way low ~ 80 degrees.... Hmmm, this was somewhat odd to me, should have been closer to the 105 setting I had left it at.... It was as though I had originally been turning it the wrong way (slotted sprockets)

Anyhow, readjusted and came out at 105.5 degrees....

I'll probably go through it one more time tonight for assurance, not to mention I'm being a pussy about it, lol!

All is good where I can finally get this going....

Found locally Kreme's Blue coat for the inside of the Kerker header.... Coat the internal header for anti bluing... I'll keep all posted if the shit truly works... Kinda spendy stuff ~$30!

OMR

Before firing up this old girl, had to get the Kerker mounting brackets fabbed up so in this image, just on there to see how she'd look....

We,ll got pretty excited so bolted on some other stuff for a teaser...

Still have the following to complete:
Kerker mounting bracket.
Possible Carb jetting (Kerker 1.5" baffle) & tuning.
Acewell 4000 Digital speedo/tach, June.
Electronic Ignition timing adjustment (timing light).
New tires.
LED turn signal mirrors.

Oh yeah, almost forgot... Küryakyn™ Footpegs for the wifey poo!

OMR

It's not shiny enough yet;)
Wow!!! I have waited so long to see it all together. Words can not express my joy:blush:
You are probably pretty excited, as well.
