Re: 70 degree valve check/adjustment

Hi fizz.
I have used a mixture of shims in my bike and it's fine.
The Harley ones look ok but have a sharp edge to them, not as well finished as the ones I got from my KTM dealer
which have "hot cams" etched into them, they must be another aftermarket brand as they look different to the factory shims.
Now that two piece look you were talking about on the factory shims is just staining and slight wear, what you can see is the two contrasting differences.
Staining from oil and heat, wear from where the valve end contacts the shim, or on the other side where the rocker arm contacts the shim.
I have added some pic's and on one I have lightly sanded (scotch-brighted) half of the factory shim to show that it is just one piece of metal.
Hope this helps,
Jason

Re: 70 degree valve check/adjustment

It's also a really good idea to use a micrometer to measure the thickness of the shim:

a) Just to verify that it isn't mis-marked
b) To find out *exactly* how thick it is. You can have two shims marked 300 ... and one could measure 301 and one could measure out to 302. Then you have the option of choosing the one that is closest to your needs.

You can also ask your dealer to swap shims with you. I am a good customer and they Parts Guys know me ... and if my shim is in very good condition - they'll just swap me and drop mine back in the right shim holder. Which is why I take my micrometer with me when I go pick up shims. You know, better measure that puppy. (grin)

Cheers! E-Ticket

Re: 70 degree valve check/adjustment

Here is a picture of the Crank Locking Bolt or as they call it in the parts list:
ENGINE BLOCKING SCREW 0113080802

It is just a 80mm long standard metric 8mm bolt with standard 1.25mm Thread Pitch. Only thing special is it has a Allen Key head on it and the end that screws into the motor is tappered.



Here is a picture of the Allen Key head. I think the US folks call it something else. Actually I think it is called something else in Australia too. Arrrrr a picture is worth a thousand words

Re: 70 degree valve check/adjustment

Many thanks to all that posted instructions on checking and adjusting valve clearances. I finally had to shim my left intake valve. It was actually much easier than my Honda CRF250X! That was a refreshing change.

I actually found the instructions in the manual to be pretty good, even though they lack detail. By following the manual and referring to info posted here, it all went pretty smoothly.

Since the instructions in this post are fairly lengthy, and two different methods are discussed, I decided to put together a short document describing the process. I stole photos from some of you, as well as used some of my own.

I would appreciate it someone could review the document and let me know if there are any errors. It can be downloaded from my public Drop Box:

Re: 70 degree valve check/adjustment

I didn't remove the tank the last time I adjusted the valves. That saves a fair bit of time. Removing it gives you a little bit of extra room, but not enough to be worth the hassle. I just slipped the airbox seal to the side to get a straight-through reach to click the cam chain reset button down.

I also didn't remove the spark plug. Not sure why that's necessary.

Thanks for compiling this tutorial. It's really helpful.

Re: 70 degree valve check/adjustment

Wow - if you don't have to take the tank off, the whole process would be much quicker. Taking the tank off and putting it back on is the most difficult part.

Removing the spark plug just makes it easier to turn the motor over, but with a decent cheater bar on the counter sprocket bolt, it probably isn't necessary.

Thanks for the time saving tips!

Re: 70 degree valve check/adjustment

Does anyone know if you might be able to achieve TDC by taking the spark plug out and somehow using the cam sprocket to turn over the motor? I have an auto clutch and I'm about to check/adjust the valves. I'd rather not have to drain the oil and take the clutch cover off..... ???

Thanks

Brandon
