Type in "dB Killers" on e-bay and you'll find loads. I had some in my toolbox "just in case" but have never needed to use them. At Brands last month a poor soul (who I hed never met) with an SP1 failed the 105dB test so I let him have mine - he passed as a result and was able to do the trackday. I let him have them for 20quid as that's all they cost. He was made up. The bike was effing loud before so I'm not surprised he failed. I suggest you get some. R |
