Cam Lobe postions for shims?

[Allie]

omg that video is bad medicine. I lost track of all the shim slaps that happened in the space of a couple minutes. "I hope that's not bad for it"... On top of it he whips out his trusty magnet to magnetize all the shims which the manuals expressly warn against. Wow, take it down!

A small screwdriver along side the shim tool keeps it from slipping off.

Haven't tried that, I will on the next adjustment.

No need to pull the spark plugs.

You have to rotate the engine somehow to move to the next shim, removing the plugs makes it easier.
I like to pull them to check wear and condition, anyhow.

No rotating the engine to remove shims.

As mentioned, you have to rotate the engine for other reasons, what's one more?

No foreign material getting shoved in the combustion chamber.

A quuick blast of air before removing the plugs takes care of that.

Ed- Given I have aftermarket cams, is there any other way (or special tool) besides cable-tie method? Wonder how the hot-rodders check valves?

Frank..you dont need any stinking tool..do the zip tie just like we did when i showed you how to do valves. Save the 10 bucks for a burger and beer at bike night.

Frank,

Those cams you have make it almost impossible to use the shim tool on the #2 & #3 buckets. I'd use the zip-tie method for your bike, or at least for those inner cylinders.

Honey badger CERTAINLY don't need not tool - he probably don't even need no shims, he just intimidates the valves into compliance.

[chuck hahn]

Allie...i saw the earlier post..any loosened carbon wont hurt the engine any..just get ejected out the exhaust the first few rotations of the engine. It will crumble to dust and not be of any harm to anything in the cylinders.

Really?

I have a set of Andrews cams that I have had in 3 engines for over thirty years.
I have adjusted the valves on them more than once.

It's not good to assume.

Franks cams are not Andrews brand. I don't know what brand they are, but they are not Andrews because the markings don't match. My guess is they are RC, but I can't confirm that.

The cams are not ground in the area next to the inner lobes; they are rough cast with raised lettering and the shim tool will not slide around the cam. Using the wire-tie method is the easiest way (I think) on those particular cams.

[chuck hahn]

Ed is right. When i went to Franks to show him the process, I took my tool and the Zip tie method is the only way to do it with the cams in his bike.

So?
Neither are the Andrews.
Again, so?
Still a simple task.
E-mail already sent to Frank if he wants to do it the EASY way.

Daniel

[chuck hahn]

He already has the EASY way...And he is quite competent after ive shown him how to do it and map the shims in each valve. Got him squared away on every aspect of what he needs to know. I read his post as asking a question if an aftermarket cam tool was available..not that he has any quams about being qualified to do an adjustment or in his skills using the zip tie.

Why don't you share on the open forum what your magic trick is? The regular bucket depression tool will not work with his cams without some workaround.

[Frank Z.]

Daniel will be bestowing me with the mystery tip next time i do valves... then i sell secret for fitty dolla.

Now that i've thoroughly hi-jacked this thread... just noticed i'm hanging out in the twin cylinder engine section. Uhhh... carry on.

OK, my son and I adjusted the valves on his 1000G last night. I showed him the tool and how it is "supposed" to work.
As luck would have it, the first time I slipped it into place, it worked (#1 exhaust).

Moved to #2 exhaust. After slipping the tool off the edge a couple of times, put a screwdriver next to it to hold it in place. Yeah, the tool did not slip off, but now I could not lift the shim completely out, as the tool was crowding it a bit. Since my son had just seen the tool slip and heard the force of the valve slamming home, he suggested the zip-tie method for comparison.

OK, so he learned from a biased source but he is a confirmed believer in the zip-tie method now.
