Very common in these, covered quite a bit here on this forum.

Run a leak down test, you may have cracked a cylinder head. Not at all uncommon.

Aos ??

Would AOS only blow smoke out of 1 pipe?

Can't find any posts describing similar experience here. Can someone please give me a lead.
Thanks

Also noted that smoke clears up at higher rpm. Still just right exhaust pipe. .....?..
