My initial thought would be that possibly the tolerances might be a bit close and the engine needed to "wear in" just a bit more. Ring and cylinder tolerances could easily have caused those parts to have seized and scored the cylinders or perhaps broken rings. That's assuming the ports were properly chamfered and didn't catch the rings. It does sound like there could also have been a heat issue if both sides went together- judging from the compression loss.

There are other possibilities too. A look inside ought to tell some things. I would almost doubt that a dealer would warranty the work when you ran it like that with such low miles/time on the rebuild. Doesn't hurt to ask.

Check the carbs, make sure all the rubber mounting on the carbs and stuff is all tight and secure, check for cracking etc , and clean them out.... make sure the coils are all hooked up good, grounds secure etc..... Its hard to say what might have cause the issue..

Could be rings.

Something similar happed to a friend of mine.

Did you fog your engine for summer storage? Or put a little oil down the cylinders.

If you did not rings may be your problem.

Good idea to put a little oil down the cylinders the first time you start the sled for the season to get rings/cylinders/pistons lubed.

I would put a little oil down each cylinder anyway even if you are back up to 110psi, give her a few pulls without the plugs in and give it a go.
