XT600E carburator issue at low RPM and bad start
Hi, to best explain my issue I have created a youtube video. Please have a look:

The issue in short: When warm, it does idle (but never for long). When driving low speed, it is not smooth, it stutters and hesitates. It seems to do this only at low RPM.
What I have done to this motor so far:
- Top end overhaul
- Cylinder, rings and piston inspected and good
- new Yamaha OE gasgets and rubbers where possible
- Valves lapped
- Valve clearance ajusted
- Cam shaft bearings ''refreshed'' (see other post). I ended up sanding down mating surface to as best as possible get bearing clearances. Seems to work ok for now but planning to do better in future.
To the carburetor:
- inspected membrane (2), look ok
- Cleaned all ports
- set screw (to be beleaved air screw to 2.5 turns out)
- replaced rubbers where necessary
- Inspected boots to engine and checked for vacuum leaks with brake cleaner
All input welcome with regards what I can try. Thanks!
