Regarding the 'holes': All K1200RS have them the same. Rider's right is the air intake, rider's left is a flat 'plug'. Pirate's Lair used to sell a tube that you could install after cutting the flat piece out, but it is no longer available. The tube was then routed down to your left radiator to add to the cooling air flow.
While it is great you have the 130bhp version, your bike appears to have the stock pipe....given that, I recommend you consider the Rhinewest Cam Gear/Chip kit. I have it installed on my 2000 model and love it. More power and more torque in the usable powerband. It is only available for bikes with the stock exhaust, definitely more 'bang for your buck', or Euro as the case may be. I feel it is a better investment than an aftermarket exhaust pipe, by a large margin. If you cannot do the cam gear work yourself or do not want to pay for it, they also have just a chip upgrade which is still better than stock.
