Purchased my leftover 2018 last year and really like the V..The remarks from members here about the ecu flash stoked my curiosity to the point where I removed the unit and sent it over to Shoodabeen. I can say that I am pleasantly surprised with the change. No longer am I lurching towards the bars at slow speeds due to the nasty engine braking. No longer am I lugging through town looking for the right gear. Riding on and off since the 70's but this V had me feeling like a beginner at times. The shifting is now super smooth, finding my gear pace is easier and the V now quickly accelerates faster to highway speeds. Only have a few hours on the flash but I think I can hear a slightly lower rumble to the stock exhaust also? Looking forward to setting sag and suspension to make this a truly versatile machine, now that the motor and gearing are happy......
