Tony,
If you have worn needle jets (emulsion tubes) you need to replace them

Taking off the air box and using individual pods is going to make you do an awful lot of carb tuning UNLESS you read up the "tuned length air inlet trick" and then follow thro on it, will save you a lot of faffing with the carbs

DO NOT change any jets until you do the trick or you will spend your life "carb tweeking" and NOT riding the bike.

Your call !


OH yeh put your location in the personal profile area or no one will remember your a Brit !
Brit bikes are different to the US & Euro models in a lot of detailed ways
