Well, took her on a 5 mile spin..
Shes pretty rideable,very light on the throttle though once warmed I can tell shes generally running a bit weak , mainly mid-range.
As per
ippytattoo , Im going to raise the needle using shims to see if I can improve this. Idle is also slow to settle so I'll up the pilots while Im at it .
Out with my box of jets this afternoon.
Ive noticed the needles in this set of carbs(From the Er-5) are different
N48Eto those in the GPZ carbs which have
N36Nneedles fitted , see the photo below, theyre stepped differently , the ER-5 (the carbs Im using) have needles that have a
longer taper...
GPZ500 left. ER-500 RightLooks like my ER500 needles , being narrower (=richer) & having a more gradual taper(=smoother transition) in theory are the ones to stick too
What type are yours ippytattoo?
