I have a Dominar 250 2020 model and my current odo is 13500km. 4 services over. My issue is peculiar and long term no solution for it. So i would like some expert explanation on this as i didn't get any so far. What happens is my bike feels clunky every morning while starting to ride and it becomes even more worse as i travel further. Power lag inccreases reduced gear shift ratio, increased vibration and Stressed Engine. When i park the bike for sometime and ride it the bike becomes very smooth and behaves normal for sometime and the issue again creeps in after sometime. I have tried explaining this to service center several times and they don't seem to understand it. Can somebody explain what's causing this issue. Initially thought bajaj oil issue and switched to motul 7100 10w50. After that also the issue is still there. Replaced airfilter in the last service bike was normal for sometime and again the issue came back. Cant ride bike peacefully beacuse of this. 3rd gear is the main culprit, it's that gear i used the most inside city. Normally i can go from 30-50 in that gear. But when tbe issues happens the gear ration reduces to 25-35 and the bike behaves very stressed below and after the speed in 3rd gear. This rapid drop in gear shift ration happens in other gear also.
