    Mine has a 7 stamped on it which usually means the size try a chines pit bike one for a 150..
   I put one on a CR it fitted like a glove.

I think its 14mm. I have only ever had one apart too many years ago to be 100% sure.

Hi All,
         Thanks, just trying to buy one, going to try a Chinese one, but there are quite a few sizes. Now I know roughly what to look for thanks.
