I installed my danmoto exhaust that arrived yesterday. Sounds awesome. I donno if its just in my head or because the exhaust is so much louder but it seems like it hesitates. If im cruising at 4 grand then go WOT, it seems to take a split second then go. Also seems slower to accelerate at WOT from 120km/hr to 140 km/hr Could it be running too lean? Is this normal? Maybe its just all in my head? Thanks.
