Hi All,
I have two Ambos...a 69 and a 70. The 70 has about 500 miles on the new
engine.
The valve clatter on the 70 is a bit louder than on the 69 (with 30k on the
engine). When I measured the valve clearances the 70 is loose on the feeler
guage (I set intake 6 and exhaust 10). What I mean by that is that the
feeler guage makes contact but slides easily. On the 69 the feeler is a bit
tighter.
I'm not sure but do you think that the little differences noted would make
the difference in the clatter?
By the way...both bikes run tops.
Regards...Ian

Hi Greg, I don't hear much sound from my timing gears (I believe they are helical |

| '69 Ambo are barely noticeable at speed (with a full-faced helmet and windshield), but a customer's Eldo I just finished doing a top-end rebuild |
| has quite a bit more noise. In his case the original rockers are worn where they contact the valve and the used set I put in have slightly worn |

| more noise than the "T" and later bikes. In other words "these motors are typically ticky". Better to hear the valves and know they have clearance, |
