mikes xs 750 big bore kit piston ring gap

[desmodromic]

I'm helping out a friend install one of these. Anyone have the piston ring gap spec (min and max) for all the rings? Is it the same as stock?
Thanks

"Always check piston to cylinder clearance and piston ring gap before assembly. Piston to cylinder clearance is 0.06mm (.00236") Maximum clearance when new is 0.07mm. (.00276") Minimum clearance new 0.05mm. (.00197). Minimum clearances above should only be used if initial break in is done when weather is cool. A 200 mile break in period is recommended and the oil be changed at 50-100 miles. Measure piston to cylinder clearance at 90 degrees to the piston pin with the piston in the bore and at about 1/2" into the bore." I got this from Scabber

1st rings at.012" .305mm
2nd rings at.015" .381mm
oil rail at .008" to .010".2032 to .254millimeters
expander (no gap)
Also some good reading here from when I asked the same question

I can't locate the install instructions for the kit I put on my 75 but as I recall they listed the specs.
