I would try to nail down why and where the oil loss is happening first.
It may be lost through valves not seating, or it could be through the spark plug seals not doing their job.
Have you been seeing any smoke from the exhaust on start up or when under load?
Any recommended shops for boring and shaving the block. - I used a local shop
Is .0025 - .0028 clearance for these pistons? yes
What does this increase the displacement to? 1052cc
Noticable increase in power? yes
If budget allows anything else I should have done while I am in there? . sky's the limit, but cams would be my choice.
Thanks Steve. I reread your article and it is actually seems pretty straightforward. I need to determine where my oil is going too before I get in there. This is the second Connie I have had and both used what I think is excessive amount of oil. This one isn't too terrible ifI drive it decent but I don't do that too often Don't do a super fine hone, 220 to 280 will be fine.

I have been boring motorcycle cylinders for 35 years. PM me if interested.
If you cut the deck of your block, your cam timing will change.
Piston clearance depends on manufacturer.

the pistons are oem, and decking is necessary to make up for the compression height (pin height) of the piston. A .040" cut on my deck resulted in 3* retarding . Steve
Thanks David, I may be contacting you this winter.
Steve, I have a few more for you ??
Does the 2 minute mod work well with this? Of course
How about the exhaust cam sprocket thing (can't remember what it is called? Of course
Will I need a piston stop for degreeing? Of course
What side of the crank works best for attaching the wheel? left
I assume you just filed the sprocket holes a little to slot them? I punched new holes.
Thanks a bunch. The cam degreeing will be the toughest part for me.

it'll run on 89. didn't try 87, maybe. If you relieve the combustion chamber, then yes. See my video "deep inside shoodaben" - I relieved the chamber to lower the compression ratio and pressure, along with better flow. it does pull harder at rpm over 8500 than it did with the high velocity head.
