Hi folks.
can anyone offer advice on upgrading the standard ADG needle on a standard marina HS4 FZX 1189 (wax stat) carb. I'm currently trawling through the charts looking for something with the profile of the david Vizard recommendation BQ or DZ fixed needles which are not the required sprung type. Burlen do an adaptor which will be a last resort if I can't find a suitable sprung one.
The ADG being the standard needle is too lean at cruise and is impossible to richen correctly. Idle is ok as is fully open. The reason I need something richer is to compensate for the K&N carb and the four branch free flow exhaust. These are the only mods so far.
Any ideas?
Cheers,
Scotty
