Here are some picks of my 750 build, just swapped it into the frame a few days ago

Dyno Dave identified these early cases as having a few carry over characteristics, there were in really good shape regardless (no play in intermediate spindle, , but I modified them for the comstock rear case breather, reinforced them, installed new cam bushes, had to openn up the cam tunnel to fit the Web312 cam, installed new superblends etc..

Some build picks


New H beam rods from Don, crank was dynamically balanced to suit

reaming out the crank for 3/8 studs

the 3/8 nuts don't clear the flange on the 750 crank so I had to shoulder them to fit

head work by Mr Comstock

new rods installed, as with other's experiences, the 3/8 rod bolts contacted the cases so I had to chamfer them for clearance

I reinforced a cradle and swingarm set I picked up for a decent price
Some build picks

cam degreeing was helped by the new cam sprocket RGM is selling, it has 3 keyways on it, allowed me to get the few degrees of advance that was suggested by JC and others

pistons ready to install, skirts and crown coated with the thermal/slippery stuff (yes, I know the risk)

NOS barrel was sourced, it was on original bore but I went to +20 to clean things up anyway, used the TotalSeal quick set powder on this job, we'll see how it goes

head going on with the new kibblewhite pushrods I bought

all buttoned up, AMR sump mods were applied to this cover

Nice.

Did you dynamically balance the crank?

I cant help but noticing the porosity of the head casting, especially compared to the FA heads. :eek: But the lightened rockers should be good. Did you have the spindles drilled as well?

Yes, crank was dynamically balanced to 54%, they sure carved a lot of meat off it! I only lightly worked the rockers, basically just took off casting marks and high spots, then polished. Didn't touch the spindles.
 
I sourced the gauge from fleabay, liquid filled, $20... the braided hose and fittings I already had lying around. fabbed up the bracket from some 1/8" alloy sheet
 
Very nice but can I point a minor mistake out? The dipswitch lever on the left bar is backwards. The extended part should point towards the grip.
 
Some nice looking goodies going in there.

Where exactly are the cases reinforced?
