Default YS 53FZ having problems at the top end.
The bubbles are normal. Don't worry about them.
The problem is likely a piston/ring issue which need to visit our service dept for correction.
Send the engine to:

YS Service
1295-C Industrial Court
Gardnerville, NV 89410

Be sure to include a description of the problem.

Thank You,
Dave
