Generally an .032" shim works very well; your shim (.5mm) is a little thin but doubling up (.039") would be slightly too large but may still work pretty decent, on the other hand I have not heard of anyone using two shims.
where can i get a .032" shim ?
I tried two shims recently on my 09 and it ran like ****. Just use one and you will be fine. Its the jetting of the main that is going to be more crucial than the shimming of your needle.
