hei im telesi I own a xtx 660, 06
i come from Ljubljana Slovenija, got it in autumn
found ur page on google looking for co adjustments, fuel fix...
i fitted a dna stage 1 & 2 filters, akrapovič slip ons without noiser, snorkel still in for now, attending to take it out - no PC.... adjusted CO to 23 any suggestions about the CO less or more i read the forum but a lot of diffrent setups ? anyway the bike runs way better less surging it gain 10kmh to 15kmh on the top speed, front takes off in second without the clutch, with stock gears! if anyone has the sam setup please reply... the only problem is sometimes it dies when i give it just a little gas, on standstill im thinking to increase the rpm....thats it for my newbie winter!
