900 carbs and airbox on my bike ?

hello again,
i have found the code on my carbs are VB51 ,which i think are CB900F ,i already know its got a 900 airbox,
i suspect the original parts will be hard to find so my question is
should i wait for 1100rd airbox and carbs to become available
or should i get my 900 carbs rejetted by dynajet etc
or can anybody tell me the jets to put in and save me the time and money ?
or are there any other carbs off a different models that will fit ?
thanks
steve

ps – how do i open the ” widget” carbs page
