amazing you mention this....i recently picked up a '03 k12gt like yours, mine is greenish silver, and i love the bike as well...it is now the only one i use....i don't have the chip, atleast i don't think i do, but it came w/a 2 brothers exhaust and my cloths stink as well, every time i stop at a light i get overwhelmed w/hydro carbons of gasoline...your not alone, i attribute this situation to the exhaust tip being so high up coupled w/the fact that the bike burns real rich...don't you love that power and acceleration?? well it comes at a cost apparently, when i bought my bike the previous owner gave me the stock exhaust which actually contains a catalytic converter, that would remedy this whole issue, but would wreak havoc on performance...and i see your wondering if its the breather, well, thats easy to figure out, just get a flashlight and look strait through the front of the bike from the forks to view the top of the engine and throttle bodies, if you have a broken breather hose, that whole valley will be soaked in oil....i had that issue, and i took it all apart, what a bitch....it turned out that there was no hole in any rubber but it was oil seeping around the throttle body rubber plenums, i think if you accelerate real hard, then release the throttle, during the deacc., the breather blows more crankcase gas into the throttle bodies than it can handle or take in and i think it pressurizes the intake air box and plenums and actually blows out the intake port in front of the bike and at the throttle bodies the oil saturated crankcase gas seeps through all the plenum splice points and leaves oil residue on everything....really a crappy design...i was going to reroute that whole system but then read somewhere that the oily air was needed to lubricate the throttle plates....sounded good so i just reassembled everything and re secured it...but i do smell crankcase gases as well sometimes and still have some oil seepage, also. i read some where that if you keep your oil level really high, there will be more oil in the breather system, this also sound like it makes sense... sorry for the long winded answer.
