i asked the same question a few months ago. the answer to the "how much" question was somewhere along the lines of "more than you might think," "a lot," and "enough."
it sounds like a sewing maching miked through a marshall stack. ticky ticky ticky ticky.
if a) oil's getting up there and b) you just adjusted them to spec and c) they're locked down and haven't moved, then they're fine. they make noise. it becomes very comforting, like my wife's snore. i can hear the valves over the engine at 70 mph.

The valves would have to be very loose to do damage. They only have to be a tiny bit tight to do damage. So, err on the side of loose, if you err. Some engines are noisy and some are quiet...it has to do with the centers of the cam bush holes, idler shaft, and crankshaft main bearing. Ones which are slightly farther apart, are noisy, closer together are quiet.

Both my T140s make a happy clicking sound. It is totally normal but if it really bothers you... try some of the earplugs that swimmers use. It takes the 'edge' off the sound and your ride will be more pleasant.

Hi,
sorry to drag this old post up the line again however there`s something I need to know:
Aren`t there any bigger (or smaller) gears (camshaft, crank, intermediate) available ?
See, at my ole Shovelhead I once needed to exchange the wheel of the camshaft.
But there are 5 different sized gears available. The diameter differs by 0.01"
With some hardenend steel-pins I borrowed from my local Indie-Shop I was able to find out the correct sized gear (which are color-coded).
Is there something similar available for our ole engish girls ?
Either the tappets or the gears is it intermediate, cams, crank are giving me headache....
btw: Is there a way to get the camshaft out without taking the tappet-block off (and therefoe the cyl.-head) ??
Thanks
Ray.

Noisy is okay, just MAKE SURE THEY ARE PROPERLY ADJUSTED!
happyray: You can't pull the cams without splitting the cases. No way around that. To split the cases, you must lift off the top end.

Better the resurrect an old thread than create a duplicate i always say!
I have a '79 T140D and I just started riding her again after about 6 months off riding a newly purchased bike. I took her out the other day and she is chattering like a fool! She never made this much noise before. I'm a little concerned with overadjusting the valves but damn she's loud and obnoxious now. If she were a car I would be worried that the oil was low.
Speaking of which she is definitely much leaker now too. Not time to put her in Depends like my Ganny but she's got some puddles at her feet!

intake .008"
Exhaust .006"
When adjusted Cold.
And it is a shame what hydrolic lifters have done to people over
the years. Ah, what happened to the 60's?

I dont know, My TR is a chopper, The Exhaust is too loud to hear the valves!BTW, extra wet sumping correction for you folks, a chopper style side stand,(heavy left leaning) will cause a severe wet sump condition if allowed to run too long on the stand, as the oil is pumped to the primary side of the engine, and is too far away from the pickup tube and cant be scavenged!
