1. Ok, #1 adjustable needle should've come with your DynoJet kit. What main jet sizes came with this kit?
2. #3 needle has more gradual taper at tip than DynoJet needle? Can you take photo and post here? Are you able to zoom in and get clear view of numbering on needle?
3. What main jet size came with bike?
4. what brand 2-1 exhaust is on bike? Please post photo
5. have you verified petcock flows petrol continuously when vacuum is applied?
6. have you confirmed that needle collars are installed with correct orientation? Internally, there is tapered end. This should face away from main jet and towards carb-venturi / needle.
7. what procedure did you use to clean carbs
8. measure all valve clearances and post here.
There's basically 3-4 areas of concern that may be causing you problem. Most likely you have them all to certain extent. Your data will point towards ones to address first.
