    Thank you for telling us your conclusion. I'm not a good diagnostician (i.e. bad mechanic) so it is always enlightening for me to hear about motor problems that are driving other people crazy. I'm glad you got your bike running well.

    That's good news, James!

    So your test ride was fun?

    Absolutely! And through my carburetor education the idling and throttle response is better than before. And don't think your vacuum leak advice fell on deaf ears. I get it, and it may come in very handy some day. I appreciate your interest and input. Thanks again!

    Glad to hear you have solved the problem. (caused by the DPO - dreaded previous owner - who converted to solid lifters?) Are you now setting the valves according to the early model values of 1 thou on the inlets and 2 thou on the exhausts - cold?
    I might suggest a re-check after 50 miles or so to see if the lock nuts really lock.
    Good riding!

    I set them cold, with the push rod at it's lowest point of travel. First loosened the adjuster to get some shake in the rod, then turned the adjuster to remove all movement, but still being able to spin the rod with thumb and forefinger. Then tightened lock nuts, being careful not to over tighten. I will definitely check the locknuts after a few miles. Thanks for that suggestion AJF.

    Sounds about right, James!

    Do you have steel or aluminum pushrods?

    James!

    Because of the different thermal expansion, aluminum rods like to be a lot tighter than steel.

    (My 86" Pan liked them where I had to put a rag on my fingers to turn them; Otherwise, they clattered when *warm*.)

    The quality of aftermarket "kits" varied enormously over the years, so if your adjustments do not seem to last, please inspect all bearing surfaces for decent contact. And if there are 'idiot springs' beneath the slugs replacing the hydraulic units, put them in your spring stash.

    Thanks, I'll keep an eye on all this. No "idiot springs".
