Have 2018 Cafe Racer and bought Arkapovic slipon. Have read that it does not need tuning. Does anyone know for sure..? I know for the best gain's in Hp. and trq. it needs to be and I will get it tuned when I bring it in for the first 600 mile tune up, but wanted to put it on before. Have 250 miles to go. Do not want to run lean and ruin the sensors. ANYONE POSITIVELY KNOW??
