Interested in a SWS Track Day ?

I prefer quite bikes anyway

I'd like to do a track day and castle coombe is a reasonable distance for me to travel that day. I'm going to use the SV and not the GSXR though. I'm quite happy to shove the standard can back on it for a day doesnt bother me.

It would never get through the noise test with the blue flame on it like it is now. It might pass with the baffles in as its passed an MOT like that, but personally I'd not chance it.

I did a track day there last autumn (other thread )

They are pretty strict on the noise limit. You get properly tested at a standstill at the start of the day and get a sticker for your bike. However they also monitor everybody on the track as they come round at the start of the start-finish straight, just in case any dodgy type swaps his can over in the paddock. This can cause problems if your bike makes significantly more noise when moving, from induction noise etc. One chap kept getting pulled off every session to get retested.

Also some people were having trouble even with road legal setups. One bloke, on a gixxer I think, was over the limit on what he claimed was a totally standard bike.

However, it is a nice circuit , and the day was well run (not that i've got anything to compare it to) . Llandow has no noise limits but I've heard its a pretty dull circuit.

It says about this on their website

In our experience the following machines may not pass our strict limits:-

Suzuki GSXR600 – 2006 model
GSXR 750 K6 & K7
Yamaha R6 – 2006 model

There was an article in one of the bike publications, possibly MCN a week or so ago that was stating that different bike circuits used different methods for testing the noise.

There was a standard one that checked the bike at certain revs with the measuring deivice at 45 degrees at some measured distance away from the end can. A standard bike or one with a road legal system should have no problems in passing this. Other places used different criteria where even an after market road legal system could fail. IIRC the example was some bloke with a Gixer 600 with a road legal Yoshimura end can.

I think I'd take my bike and get it tested first as it now sports a road legal Yoshi that I got with the bike. If it fails, well I still have the standard can. It's just a pain to fit with all the clever exhaust valve cabling stuff.

I'm interested... but I don't want to go all that way to have my can fail.

Neither do I thats why if I go I'll put my standard can back on. Its not a huge job and TBH the peformance exhaust on both my bikes makes naff all difference to the performance anyway.

Problem most SS bikes have nowerdays is part of having a less restrictive can they have a flapper valve in the exhaust pipework that is used to increase the low down power of the bike but also makes it quieter at small throttle openings, now at 3/4 throttle the bike is going to be reving a fair bit (12k ish) and the valve is going to open up making the bike very loud. If you could find a way of disabling it when the bike is being tested then you are more likely to pass but they may have become wise to those tactics.
