Topic: Help with adjusting valves

[cb500-1972]

i tried to adjust my valves today, but i couldn't get my feeler to fit in the area i was to measure.

i have only done valve adjustment on a beetle earlier, but there i could fit the feelers right in.

do you have any pointers on how to do this? bend the feelers in a 45 degree angle to make them fit? i don't have access to "pre bent feelers "

if you have a picture of how i should do it then please post it

question 2: fron the fueltank there goes two hoses. do both deliver gasoline during driving?

There are feeler guages designed for this work. You will have a hell of a time trying to do it with the big blade feelers.

They look like this:

You can pick em up at most cycle shops.

Remember to err on the side of loose.

+1 on the angled feelers. I did my first valve adjustment a few months ago, and I definitely would have had a much more difficult time with straight gauges.

Did you check your manual to be sure you have the valves in the correct position before you insert the feeler gauge? You use the timing marks for reference. You will have to rotate during the process for all valves.

+1 on the motion pro angled gauges.
+1 on making sure you're gapping the right valves.
as you pass the T1.4 mark, you should have a few thousandths play in either cyl 1 (intake AND exh) or cyl 4 (intake and exh)

It takes some practice with a regular feeler gauge but you can do it. Just loosen the tappet screw enough to insert the feeler in between the tappet and valve then tighten down enough to barely be able to wiggle and slide the feeler then tighten the nut. Leave the feeler gauge in place to make sure it is the same gap after tightening. Pull it out and move on to the next valve.

And yes make sure your TDC is correct for the valves you're adjusting.

The angled feeler guages will make it allot easier.

I paid $5 each.  Any decent bike shop should have them in stock.  You shouldn't have to order them online.

I also bought the adjustment tool and it helps as well. It basically holds the adjuster nut while you tighten the screw.

Gee, I just bend the ends of my .002 and .003 feelers and go to it. Isn't that the same as the specialty gauge from Motion Pro that's pre-bent?

Just get a normal set at Sears and bend them, I found the crappy little ones they have at the moto shop sheared way too easily.

two fuel lines supply both fuel at the same time,one to the left pair of carbs and one to the right,whether the tap is on reserve or main.

its in the original post,"question 2", umm,have i missed something?i dont need a sharpee,im pretty sharp as it is.

Yes, Dave, question 2. Two fuel lines from the petcock, one routes to the left carb pair and the other to the right carb pair. Doesn't matter how the petcock is set, as regular or reserve.

at least popwood is on the same frequency.

I figured out how this could be easier, but it depends on having a friend at a machine shop.

I still haven't consumated the act, but there is something they use called shim stock.It's made of brass in several thicknesses.  I called and asked him if he could find a .002 piece 1 cm square.  No problemo.  Rediculously easy for those machinists.

Along with a  pair of hemostats and I think I'm in biddness, tight quarters in those valve cover holes  and all.


Maybe I can cut up a few pieces and spread it around.

I like your creativity, but i fear hat one little slip and you are going to be cursing a lot.

I bought my feelers from a guy who was mentioned on here, his place is called Loud, Fast, Ugly, for like $5.  Bynthe time you have the machine shopncut you a piece, they may have arrived in the mail already.

to be sure,rotate the motor as you watch the inlet valve close for that cylinder,then look at the timing mark approach tdc,repeat this for each cylinder,have the spark plugs out ,its much easier to turn the motor.
