What has happened, assuming your top speed was about 105mph, and is now around 70mph, is that you are dwelling in the infamous T140 flatspot, sadly it affects some bikes more than others, you have to rev through the flat spot in 4th and then change up, alternatively go back to less restricted silencers!
Cheers
