| Before you spend money on new parts it's probably a wise investment to spend a little time & cash on ensuring that the mechanical & electronic components which influence the fuelling are set for optimum running.
As well as throttles, the air bleed screws can make a fair difference to the bike.
Yes you can spend the money on an ultimap which are great ( I had one in my ST2 & it was superb ) but first I'd spend about £50 or so on a proper fuel injection setup which is what I did before moving on to the TFI setup I fitted to my 4S.
Give Nelly a ring.... that's what I did.
Money well spent. |
