The issue is I don't understand carbs well enough to know what the issue is, but I know it's not perfect.
I need to read about different faults and then come back and ride it again to try see what it is.
It revs well once moving but it bogs a bit, I am not sure if it's doing so due to lean or rich.
Check your valves and timing before you mess with the carbs. Then try float bowl height. Check cable operation including choke cable. Then try and dial in mixture and tick over.
Ohh, I don’t actually. Slack, do you mean it bogs down, or the revs just don’t climb fast?
