Hi Guys,
Could you please help me to troubleshoot the following issue.
The bike rides well generally but it has a very rough IDLE, it is not stable as shown in the video below, specially when it warms up. Also when it is very warm, it drives awfully, it missfires a lot and it seems like it has got no torque at low revs at all. In city enviroments I need to rev it more than 3k rpms to avoid stalling and then release the clutch.
I have done the following that greatly improoved the bike performance but left me still with the issues named before:
To Do:
Has any of you had similar issues and could point me in the right direction?
Cheers

I have done the following that greatly improoved the bike performance but left me still with the issues named before:
- Compression test (All cylinders more than 11bar) Great
- Valve clearance check and adjustment - All seems correct
- Change Spark plugs (No lean condition, a bit of soot even on the old ones)
- Injection syncronization
- "Z" shaped tube change
- Check for vacum leaks - No change in IDLE
To Do:
- Change temperature sensor. (I don´t think this is the right thing to do as the engine runs fine when cold and the fan has been working fine), I am aware that it is a dual sensor though)
- Change fuel filter
- Keep troubleshooting
Has any of you had similar issues and could point me in the right direction?
Cheers
