Must Have

If you have a 4 stroke, you must have a shim kit. Nice variety to help you get the valves back into spec

If you are changing cams order this kit also. Your stock cam shims will NOT be right.

its a must have when it comes to keeping your 4 stroke running right. older hot cams valve kits were labeled way better..takes you a few minutes to find the shim you need. other then that its a great kit.

Good kit

Not to much to say other than shims are shims. The kit is nice because you have a range of thicknesses. They are going to be like any other motorcycle shim out there, you need to measure them with a micrometer to get the size you truly need.

Shims

Its nice to have shims on hand, we all know that. This is the only kit I have ever bought. Only buy this kit if you have an accurate way to measure them. Measured about 15 before finding two that were within my tolerance range. Some have a nice polished finish, most do not.

What is the correct Shim Kit for a Honda Hornet CB600F 2008 Model?

MotoSportExpert
We do not have a kit for the CB600F. You will need to get the individual shims in the OEM section.

Unfortunately Hotcams does not currently offer their shim kit for the 2007 Kawasaki ZX-10R. Shimming valves on sport bikes can be fairly intensive so I would recommend doing as much research as possible before diving into this project. Pro X does offer a shim kit for your bike which you can find here:http://www.motosport.com/motorcycle/Pro-X-Valve-Shim-Kit

There are enough shims in the kit, provided you accurately measure each shim with a micrometer. Do the math for the high and low side of the spec window and find a shim that fits the window. Instillation is as simple as removing a bucket, removing the old one (with a magnet), and dropping the new one in place. That is once you get the valve cover and cams out of the way.

Shim kit for '05 Honda CBF600S?
I have this bike which I think should take the same kit as the CB600F as they are similar engines. Can you confirm whether the same 9.48mm kit will fit? THanks

The 2005 Honda CB600F would use a 7.48 shim kit.

On the shim caps, does it matter which cap goes where? are they all the same size?
i have an 03 z400 and am in the process of putting the top end back together, i think i might have gotten the shim caps mixed up or buckets ive heard them called, does it matter wich cap came off where if so how do i go about figuring out wich order is correct?

It always very important to put the caps or buckets back where they came from or any other part for that matter. Things need togo back for ware purposes. Everything wares differently so its always good to get them back where they belong.Put them back to the best of your knowledge and do the valve clearance. Just for next time put them back where you got them.

It doesn’t matter, there is slight differences with each cap but their not noticeable. the most significant change is the valve shim itself. also when you’ve adjusted the clearance, you need to always double check the valve clearance again.

It would likely be best to install the caps in the same location they came from but unless there was noticable wear on one of the caps the difference between the caps shouldn't be that significant. As long as your valve clearance is correctly adjusted to spec you should be fine.

Im trying to find out what size of shims to put in with my hot cams i have 2006 kx450f?
Top 500 Contributor
1 year 11 months ago

You don't know until you put the hot cams in and measure with what shims are in place. Put the cams in tighten down the cam caps take a feeler gage measure. Then write each measurement down. Take the can caps back off take cams out and one at a time get the measure meant off of each shim. If the clearance needs to be .10 to .15mm and you have .17 with the gauge and the shim is a 2.85, to close the gap you put 2.90 that will bring it down to .12. That is within tolerance. The shims go with .05 each shim.

This is a pretty technical question; one that might be better answered in a more technical forum like www.ThumperTalk.com.

But, you will have to install the new cams, check the valve clearance, and then determine the size of the new shims by referring to the service manual. (There is no "standard" size shims.)

Good luck!

I really cannot accurately answer that question for you. You would need to check your bikes service manual and then check your valve clearance with the shims you currently have in your bike to figure out what size shim you would need.

I would have to recommend you refer to the service manual for specific Valve Clearance Specifications for your 2010 Honda CRF250R.
