    I was going to set the valves on my oilhead and then I thought that maybe is was too cold ,20 degrees, in my garage. If I set the valves when the temp is in the 20's will they be too loose at operating temp? And yes ,I'm bored and just need something on the bike to do.

    No it will be fine.

    Your hands and fingers might have some problems in those temps though!

    You must really be bored if you can't think of anything better to do than adjust valves in a 20degree garage.:lol3

    Better too loose than too tight.


    Wait


    We're still talking about valves, right?:lol3



    Actually, I'd think that if you did it when it's REALLY cold, like zero F or below, you could end up with tight and eventually burned valves.

    It'd have to be more than 100*F below zero before it actually mattered.

    The garage temp won't change your readings. Its just going to be a cold mofo to work in.

    Something that might make a difference is if you have to use any sealers. On my Honda, it needs a smear of sealer on the two corners of the half moon shaped parts of the valve cover gasket. Sealers may not set up properly in that cold of temperature.

    I'm with the rest; for this, "cold" means "ambient" or "not hot", rather than a specific temperature. A couple of mfgs do publish a guideline ambient temp, but I my judgment would be that you'd have to be incredibly anal to worry about this. But then, I think the whole idea of setting oilhead valve clearances super-precisely with four feeler gauges, calibrated pull, etc. to be completely and utterly ridiculous.

    BIG +1 on those comments. I've set valves on dozens of oilheads, and once had the misfortune to sit thru
    an oilhead valve-setting seminar at a BMW rally; put the A in annal. Turning such a simple 20 minute
    process inside out was just sad.
