That will DEFINITELY fail the noise test at Combe. Due to the NIMBYs their noise test procedure is more draconian than at any other circuit regularly used for trackdays. A test at a normal circuit will be with the throttle held at a steady 7,000rpm on a 600. At Combe they stipulate 3/4 of maximum revs, which on a J2 I'd expect to be around 10,500rpm. R6 and GSX-R600 models from around 2006-7 fail the Combe test with a standard exhaust. Don't waste your time taking it there unless you can fit a standard can on it beforehand.Originally Posted by LucasZxr600
As a beginner on track your tyres will be fine, as long as they aren't shot to begin with. Some people mistakenly believe that it's OK to use worn-out tyres on track as there are no restrictions like on the road. Wrong. On track your tyres will get used harder than they will on the road and any deficiencies in their remaining life will soon make themselves apparent. Unlike for racing there's no scrutineering before bikes go on track, but if one of the organisers spots knackered tyres in the holding area you'll be told to replace them or go home. Even as a beginner you'll be riding faster, braking harder and leaning further than you've ever managed on the road, so make sure that your bike is in tip-top condition; tyres, brakes, suspension, oil etc.
