Its interesting to me to what you are doing with your silenser. Here in Ukraine we have not such high exhaust emition standart like it is in EC. So our exhaust have no any SAI, catalizators or shit like this. And I suspect that it have a very little noise absorbing material in it, because from first time I bought it was sounds loud. But I still never try to open silenser and to see what is inside. If you will make such a upgrade bfrt some picture.
As well I so that nippel or valve on the rear shock absorber. Dealer told me that its factory precharged and better dont touch it . Well actually I almoust sitisfied with my suspention. I would like to have lower seat (now mine even higher couse my new 21 & 18" tyres). And another think. Some of gays in Ukraine did open front fock. And its only one (left) side have a spring in it. So what do you think why is so? And is it give a good result to add spring to right one.
