So let me give you the backround.
The bike was running ok a few days ago, had some bad vibration around the 4-5K mark where you could here the whole bike buzz and the idle liked to dance once and a while. So I took it upon myself as the bike is due for its service at 30K km. I began with the valve adjustments, most of the valves were tight so they had to be adjusted but there were some which were ok. After this I went on to doing a carb sync. The carbs were off especially the difference between pairs (1&2) to (3&4). As I did the adjustment the closer and better tuned I got the more I had to decrease the idle as it was idling up. After all this was said and done I put the bike back together.
Here is where I went wrong, I flipped the vacuum and breather hoses where they connected to the tank which I found out after taking the bike for a spin. It would die the moment you gave it a quick blip and the engine was noisy as hell.
So I fixed that put all the lines so that they were connected in the right spots and took it out for another spin. The gears change ever so smoothly from how they used to and the power curve seems to be much more smoother overall. HOWEVER, after riding the idle will not come back down to 1200, it just sits up at 2500-3000. I can force it down by leaving the bike in gear until the revs are down to 1500 and the bike will idle down to 1200. But next stop it idle back at 2500. The bike does appear hotter but this could just be me looking for something wrong. The other noticeable think is that the buzz from 4-5K is now gone, but vibrations are strengthened it seems from 7-9K. Any ideas on what is going wrong? I did not touch anything else other than the valves clearances and the carb sync.
