I was wondering if any of you guys have done a valve adjustment on your 636's. I have a bit over 27,000 miles on mine since buying it brand new in 06 and have not done it yet. Is definatly overdue by a longshot, and you can hear the damn things ticking. I've done it a bunch of times on small block Chevys; I'ts the same concept, just on a smaller scale, but I am a little nervous to tear that far into this thing without knowing what I'm getting into ahead of time. I've seen one getting the adjustment done at my local shop, and know how to do it. I am just curious if anyone has any experience with this and knows what kind of hiccups to expect. Thanks guys, -Ben

The valve adjustment on a small block chevy is NOTHING like the adjustment on your bike. They are two completely different type of adjustment. Long story short, get a manual for you bike and you will see the difference.

i took her in at 23,000. valves still in spec...so they said. 400 bucks for nothing but a cam chain adjustment. thats whats probably causing the noise for you. it sounds just like tapping valves

at 27k my valves were painfully out of spec (ie .0045" off)... just the exhaust though. it's not too bad to do, just takes some patience

I agree with mstrpeter that its not very difficult to do. But at $10 to $20 per shim it can sure add up for parts. You'll want to make sure that your math is correct and that you're buying the correct shim thicknesses.

Doing it yourself will be much cheaper than having a shop do it, but it all depends on how mechanically inclined you are.

if you have access to the proper tools you can just grind em, a surface grinder lets you accuratley take off .0005 at a time :) the only cost I incurred was a valve cover gasket and new spark plug tube gaskets along with a few orings and an oil change.
