46 47T rear sprocket on 3TJ

				Hello
I am trying to find a 46 or 47T rear sprocket in 520 (or 525) for the 3TJ.
With my bulk on the bike it is topping out at 12000rpm in top .  With the current 15/44 gearing the (very newish) chain is almost at the back of the adjusters.  Tyre is a Michelin pilot power 160/60 and not overly tall.
  .  With the current 15/44 gearing the (very newish) chain is almost at the back of the adjusters.  Tyre is a Michelin pilot power 160/60 and not overly tall.
JT Sprockets seem to stop at 45, which I don't think will get me up to the red.
I have a 15T on the front and don't want to go down as I would defo have to start shortening the chain.
Other than fitting a 4JH wheel and a 530 chain..... what can be done? 
 
TIA
Chris
