I assume you are from Montreal?
I'm located near Joliette,
I just ordered a header and muffler from ryca last week.
I was thinking to pick up a decompresor lever but i decided to pass because of the 25$ for this little lever.
Their shipping charge for the exhaust with a set of grip was OK, 46$.

I will fab one for my bike but probably only next week.

Au pire je peux envoyer un PM avec une photo.

You might want to take a look at the cafe' build Dave did... he found a bicycle bmx brake lever that was perfect for the use you are asking about.

The decompression release I built may not be what you are looking for - but it does work well.  I used a different fuel tank and it sits right down near the top of the engine - there is no room to get your hand onto a lever directly on the decompression shaft.  I also am using 7/8" bars on my bike - so the BMX brake lever fits onto my bars, and you would have to bore the lever mount out to 1".

The bicycle brake lever has a long pull, so I had to build a longer lever for the decompression shaft.  There is a more complete description in the build thread.
