I believe 07 models are restricted, but I might be wrong.
Easiest way to check is lift up your fuel tank and look behind the right frame and check if there is a solenoid to activate the exhaust valve. And also look for blanking plate on the exhaust manifold where the valve should fit.
Also, does your RS have a flat spot between 5-6,000 revs? if so than it has a restricted CDI unit as well.
For service, if you are in Sydney, go to RB racing in tarren point. As for the oil, only use the best full synthetic oil you can get (Motul 710 or Castrol TTS racing will do just fine). Also dont forget to warm it up before every ride (until you have 2-3 bars on the water temp gauge)
