Airhead Valve Question

Greetings,

I recently acquired an '83 r100rt. It is in pretty rough shape cosmetically, but seems to pretty average mechanically.

I think I am experiencing the dreaded valve recession. Here's what I got:

36,565 Miles:
Left Intake okay at 0.10mm
Left Exhaust okay at 0.20mm
Right Intake NOT okay at 0.05mm reset to 0.10mm
Right Exhaust NOT okay at 0.10mm reset to 0.23mm

37,839 Miles:
Left Intake okay at 0.10mm
Left Exhaust NOT okay at 0.178mm reset to 0.229mm
Right Intake okay at 0.10mm
Right Exhaust NOT okay at 0.178mm reset to 0.229mm

Thats 1,274 miles and 0.022mm movement on the left and 0.052 on the right.

Thoughts? The PO told me that the bike probably has 50,000+ miles on it and that the odo does not represent the true mileage. Also, the title does not have an odo disclosure on it. It looks like it has seen high mileage. For example, the rear disc is almost worn out.

Ideas?

Thanks,
Lloyd
