new needles for cvk40 bike carbs

[weavo56]

Hi all , I need to replace the fixed fuel needles with the dynojet type ,the ones with the grooves in .
Had car at AB's on sat and the taper on the needle is giving me a rich fuel setting at mid throttle ( cruising ) . Its ok at idle and had to change jets from 190 down to 125 to get full open throttle right . So I'm measuring up the oem needles to see what I can replace them with .

So now you have them nearly right what do you think of using bike carbs?

A lot better ,tickover to low speed is smoother and with the short travel of the pedal you can go to full throttle very quick ;D

they should stay in tune a lot longer , less moving parts .

Got the needles today ,they came without the e clips ,so had to sorce some on net . Also decided to change the rubber diaphrams as I had a hole in one which AB fixed . But it wont last .
Will let you know after I go back to ABs to finish the car setup.
