Ive got almost 300 km on the bike and the last two rides I had noticed that the engine doesnt run as smooth as it did before. Especially at anything below 5000 rpm. Before the engine would just purr, super smooth. Its not awful now by anymeans, just not as smooth as it was. I was stopped at a light for quite a long time probably 2 min before it changed and when i took off it was right back to normal, maybe slightly better. Anyone have any input as to what might be going on?
