Hi All, Did a quick search on this website for "shims" and didn't find any mention of the following company, so... Found a good shim place here in Melbourne. I needed some shims for a ZXR250 engine and after calling Kawasaki (were $4, now $14 each!) I thought it might be wise to look around. This place does shims for everything and for the shims I needed they did .02 increments as opposed to .05 increments from Kawasaki. This means I can get clearances basically identical across the head. After swapping a few shims around I needed 4 shims and they were less than $4 each. They ship all over Australia via express post, so all good. Checked shims with a micrometer and they're spot on . Company is called Precision Shims and their website is http://www.precisionshims.com.au/ Cheers
Good work @Frankster @GreyImport We could make a sticky out of this and include the dimensions for the models so that people can order kits etc.
I got shims for my fizzer from him some years ago - very very highly recommended mentioned in this thread - http://2fiftycc.com/index.php?threads/fzr250-zeal-fzx250-valve-clearances-howto.1697/
Hey Ruckus, Great write up on a very important part of tuning a motorcycle engine (or any engine for that matter).
I got them from Chris as well. I have a bunch left over if anyone is chasing some, 7.48mm... may have your size. Got around 20.
Super good idea !. Especially for guys as myself that has never had to do shims before. If you could order a asst shim kit to suit your model bike it would make servicing it so much easier especially in country towns.
You would be able to order a kit based on projected changes after you've done the adjustment for the first time and know what shims you have installed. The first time doing the adjustments takes the most time. Keeping good notes, or better yet notes and a diagram makes life easier from that point forward. The trick is knowing what shims are in there already, it really saves a lot of time. When I did mine, I found that with the range of clearances, adjustments and installed shims, for memory I needed ~6 shims to get the job done. I still have that list of installed shims, where they are located as well as the extra 6 from the previous time. Now to do mine, I merely need to remove the cam cover and check the clearances, refer to my notes and see what changes need to be made and see if I require any other shims to get it all done. The bike doesn't need to be out of service for any length of time as it can be ridden whilst waiting for parts. I think the idea of a shim bank is a good idea to move out shims in a range that will likely no longer be needed on one particular bike to bikes which are using shims in that range
Hey, that's pretty cool.Have been looking on the web how to do this job.One site mentions that i need special tools , so what have you bought and where from.Sorry for so many questions but this is all new to me, well adjusting shims that is.Where about's on the web did you get that diagram from ?.
Check this thread, most important tool which you need besides good quality sockets and spanners etc is accurate i.e good quality feeler gauges
THIS IS CHEAP, we paid $80 USD plus postage for ours! Buy ASAP if you need them! http://www.ebay.com.au/itm/Hot-Cams...925-0010-68-2073-870966-12-5660-/231441096094
