Daytona 1200 Dreadfull Running At Low Revs

Update#3 got the bike this afternoon, it's now running perfectly having had the correct needles fitted, it's been a long haul but sorted eventually, work completed:
Valve shims
2 x new coils
Carbs ultra sonically cleaned (twice)
Correct carb needles fitted along with the correct main jets.
Dyno tested to ensure correct fuelling etc
I can't speak highly enough about the shop, many would have chased me but Dave persisted to sort everything, costs were incredibly fair. May I recommend :
BDS Motorcycles of North Shields.

 

Bike running great so thought I'd post a pic of it.
