I don't remember...what engine work did you do to it?
First a pressure vacuum test. Middle cylinder passed, right cylinder passed, left cylinder didn't.
Engine torn down but only sides and top end removed.
Connecting rod play checked and passed.
Cylinders measured, piston measured, rings measured all passed. (Ring gap on all rings were .019-.020 I suspect factory originals???)
Cylinders lightly honed.
Oil scavengers removed , cleaned and reinstalled.
Oil line check valves cleaned, hung and tested.
All parts cleaned and reinstalled. All fins cleaned and cleaned and cleaned.
New crank outer seals installed. New gaskets and seals installed.
Vacuum/pressure tested again. Right passed, center passed, left slowly leaked down after a few minutes.It held vacuum better than pressure. Might have to re-sleeve that seal section of the shaft if its a problem. I'll have to tune up engine, get it for a couple of runs and check to see if it is leaning out. It was running well before and now it can only be better. We will see.
Pressure tested 145,147 and 149 psi.
All new carb kits installed.
Without a fuel tank on the bike I used a syringe to put gas in the carb bowls. After sitting more than 15 years It started on the 5th kick. Right now it starts 1st kick but I have tuning to do.
Today was the first day I ran it up to temp.....my wife hated the smoke and smell. Reminded her of snow machining days....
