Interesting! I'd think that there would be more loss with cam timing  
on a manual adjuster than the parasitic losses, but it just goes to  
show that analysis does not beat testing.

FWIW I know of a number that have failed in this part of the country,  
but (IIRC) they were mostly on GSXRs. I did see several that failed to  
hold on one of my engines; had to replace - and they weren't that old.
