Hi, Is this normal 2017 350 xcf behavior? Only have 4 hours on the bike. For the first half hour the throttle response in first and second was smooth off idle and holding constant revs didn't seem to be an issue. After getting off the track after that first halfa the throttle response off idle now causes the bike to lunge an amount and holding constant revs is somewhat difficult. Doesn't seem to matter where the revs are at when the throttle comes back on. increasing the idle seems to help a little. Iv'e checked the cable (its pretty well spot on). I increased TPS a little above factory but it didn't appear to do anything. ECU adaptions crossed my mind. I don't recall this being a problem on the bike i test rode. Can anyone with a similar model confirm smooth off idle response? Cheers.
