why rering it? id be more concerned about crank seals than rings.

Definitely putting new seals in. I guess the rings aren't that neccessary with such good compression.  I imagine the new gaskets is more than enough. Just thought it would be a good idea for new rings.

Motor pulled.
Now one head bolt on the right side cylinder was frozen. A rachet with a breaker was laughed at by the head bolt, it laughed at my little impact  My big impact still had to work overtime to break it free. Was really worried I was gonna crack the case.
Now I can't get the cylinder off!!!

SOB right side jug is stuck like hell.
I soaked for 24 hours with WD40 .. Then heated the jug
No good. Would not budge.  So I made my 50/50  solution of acetone and ATF.
I'll give it another 24 and try again.

Day 3 of beating with a dead blow after letting the stud holes soak in acetone/atf mix. Heated the jug with my heat gun for a hour forst.
Nothing!!!
SOB won't even crack a bit.
At my wits end here.

Not sure how to drill out studs with a stuck cylinder.
Maybe a if I had a 3/8" hole saw maybe.

well would be an 8mm or 5/16 drill. I've only had to do that 1 time on an s2 motor, but would dev avoid if possible. keep soaking.

WD40 isn't a penetrating oil, use PlusGas or Ziebe Black Magic (if you can buy it?). Even soak it in a bucket of diesel is better than WD.

id get 2 gallons of evaporust and sink it in a tub for a few days upside down to cover the jugs

Likely my only last choice.
I let it sit another 24 hours with Croil.
Heated it with my propane torch..
Beat the shit out of it.
Never budged

So here I go again.
I of course lost all the R5 engine parts and stuff in the fire.
But like the proverbial Phoenix I'm not letting that little thing stop me from a R5 smoker ride.  I have a frame, a tank and some pipes that didn't get destroyed so that's a start.
This group here is special. Without it I would know nothing about these bikes and ya'll always been good folks. But without naming names (yet) I'll tell you I've been gifted a R5 lower unit.
So the quest starts again.

Unfortunately those previous projects are in a ash heap now. I'm starting from scratch.
