Weird noise help - gsxr 600 06

okay long story so i will try keep it simple..

Couple of months back my bike suddenly stopped, i pushed it home and the only way i could start it was after i placed the battery on charge. When the bike started it was making a weird noise when i revved it.(see below for more details) Took the bike to clubmans and my stator was stuffed (2 coils black) and that caused my regulator to crap it self. So got them replaced and all sweet! Bike ran fine and noise went.

Now as some may remember i crashed a few weeks back in the city and cracked my stator cover, this then caused damage to my new 500 stator! Replaced stator and cover again! (thanks to eBay saved some coin) and was over the moon thinking i could ride again and learned how to replace it,

Went to start bike Friday and again when i rev the bike it makes a weird noise , its hardly noticeable when in gear with clutch in, but when its in neutral its really loud. It sounds like its on the rhs engine case.

It sounds like something isnt tight or something rubbing, hard to explain but it echos the exhaust when i twist the throttle.

I took the bike around the block and it rode fine but the noise gets louder with more rpm.

Could this be my regulator/rectifier short circuited again? And if so why is it making such a loud noise? and why when its in neutral not really doing it in first.

Going to try get the multimeter onto the regulator but having some trouble getting one bolt off atm

Any ideas anyone? Really getting over this!
