What's your tool of choice for valve adjustment?
05/10/11 at 08:13:13
I've started the process of fine tuning my valves. 7k miles on the motor and after knocking loose the adjuster bolt I had about one full turn out of tension on my rockers (self adjusting valve spring?). I had to turn the motor a dozen times to find TDC and was very confused that I didn't have any play when the valves were closed. It's never ran well and has sat for years before I bought it from a family member. After hunting at several auto part stores I have yet to find a good feeler that will fit in the inspection hole for the valves. I bought one from Napa that will work but it's still on the larger side (0.005") and the tab is almost over an inch long. Still need to find one that's 0.003" What do you all use that fits better? I've seen a few from Motion Pro that are individual feelers but they're five bucks a pop.

2 standard feeler gages, the .005 has a kink in it so it's easier to slip in. the .004 is still flat cause a kink would do no good.
some use these...
That and a 10mm wrench.
These are handy but don't fit on the intake side...
I ended up making a similar tool using a hex drive screwdriver tip pressed into a fender washer.
scribe lines thru the center and at 90° and there you go, almost don't need feeler gages.

I figured the Motion pro feeler was probably the better way to go. Is the valve clearance different for the intake/exaust? Or can I be lazy and shoot for .004" which if I remember right is the midrange for the adjustment. That'd be nice considering that the feeler comes in .004/.005"

I use a different approach: No feeler guage at all. The adjusting screw is M6 standard pitch which is 1mm per revolution. So I loosen up the jamb nut and screw the adjuster all the way in by hand, touching the valve snug, but not too hard. Then back off almost an 1/8 turn. A 1/8 turn equals 0.125mm or 0.0049". So a little less than an 1/8 turn gets you right where you need it. That fumbling with the feeler just drove me nuts.

Screw the feeler guage, this will be accurate enough for the purpose. I bet there won't be any difference in valve noise/performance compared to a dead-on feeler adjustment.
Just an old german machinist trick.

Wow that's actually a brilliant approach. I'll have to give that a go. Considering that this will be the fourth time I've attempted to set them, what can I loose? Well... minus the potential for valve damage. I'll still have to double check that they're even because I'm mechanically an@l about that kind of thing.

And now that I think of it I have a set of hex flat head screwdrivers that I can attach to a meter to get my 1/8th turn...

Well just look at the slot on the adjuster screw like a clock. Lets say the slot points up in the 12/6 O'Clock position when snug on the valve, then a 1/4 turn CCW would put it in the 9/3 O'Clock position. So an 1/8 turn would put it in the middle between that. So i would set itclose to the 11/5 O'Clock position, put the flat screwdriver in the slot to hold position and tighten the nut, making sure the screwdriver doesn't move.

I back the 1st one off then measure it with a feeler gage, then do the rest the same way.
90° for me.
You might check the pitch of that screw.

I think the easiest tool is a credit card handed to a mechanic.

If I could do that I would have just bought a new motorcycle
Besides that takes all the fun out of it.

Not technically correct, all my savages have slotted adjuster screws.
Those have a little square on the end
And as I've said...
I back the 1st one off 90° then measure it with .004 & .005" feeler gages, then do the rest the same way.
