A source for the shim kit:

I've never ordered from them, but have heard good things.

 

Thanks, Ive had this page saved for a long time and didnt think to check it for a shim kit. $80 though.....? Any other cheaper options out there? Cant imagine you need all 141 shims for this job.

 

Hay Aaron I got my shims off e bay oem parts for 8$ to 10$ each.

 

hey ya'll, here's a crazy idea- give your local motorcycle shop a call and see if they are willing to trade shims with you. quite often they are, at least up here in Canada

I took in my two exhaust shims that were 3.00 and traded 'em for a 2.90 and a 2.93 (they didn't have two 2.90's)

Bike runs better, starts easier and doesn't tick anymore. Did mine at 10000km

 

CC Rider thats a great idea!

I will do that next time!

 

My shop "trades" for $2 a shim. Old shim + $2 gets you a new one. Still better than buying a whole set or paying $8 each.

 

I would trade if I had any to begin with. I dont mind paying $8 a piece only needing a few and to have the right tools for the job in the future. I just cant see paying $80 for a huge set I will never use beyond this application.

On ebay or wherever you might find these shims is there an industry term for the style needed for this? I work for Grainger and more than likely can get them through that avenue just need to know specifically what to look for. Shim is a very broad term in my line of work.

 

You have four of them in your engine, you would trade the shims that are already in your engine for shims of the thickness you need.
It is a specific shim. They are hardened and are specific diameters, I forget what the KLX uses (7.48mm?) and then you will need to know the thickness of the one you need in order to correct the clearance gap. I think all of this info is here on KF,you just have to find it.

 

As far as I know, they are motorcycle specific, so not sure if Grainger deals in them. Also, I agree, I wouldn't pay for a whole $80 set. You will never use them all, and you may use more of one size than you get in the set.
