Little update: So far the bike has been running like a dream. It's so much fun and power is just always there! That is until today. Today, I took out the bike for an afternoon of bliss out of town. I gave it everything on the b-roads and the bike was just so sweet and smooth. Power delivery was perfect and I was feeling very appreciative.
After coming back home, it was parked for about three hours until I took it out in the evening for some errands around town. This is when I noticed some stuttering when accelerating, especially when hard accelerating. Something that has never happened before. I think it was especially around 2000 - 3000 and 5000 - 6000. Power was still there and it was fine when going steady or accelerating very smoothly. It revs up fine when I'm in neutral, just stutters under load. It feels like the engine is not getting enough gas.
It's so weird because it was just running so perfectly al the way until I was home, a few hours earlier. It would have made more sense to me, if it happened during the ride and not after.
Carbs are clean (Ivan was just installed a few month ago) and synched, spark plugs are fresh. Exup was serviced. I have only used V-Power fuel so far, so I don't think it's possible that anything gummed up, especially as it was just perfectly running in the afternoon.
Tomorrow, I will check if it's still there (probably will be, I'm guessing) and then check all the electrical connections...
