Ganador,

You cannot get much closer to what Mikuni is saying for their stock jet sizing. #180 Main Air and #140 Main.

It is three steps richer on the Main Jet and eleven steps up on the Main Air over OEM Toyota for a low polution version of the 18R-G. I suggest leave as is, as the OEM jet set does not pull up high.

Maybe could try a smaller Pilot perhaps a #60. To get jets for these, any place that tunes Alfas or Fiats may have some. Or I could try and get some in.

Regards

Rodger

so are you saying all my jets are too big?? Ah stuff it, it runs haha.

No. From what I read they are close to what I would have suggested anyway. It should be reving and pulling a bit better over what would have been stock. Might only be a tad thursty at town cruising speeds which uses mostly the pilot jetting.

Toyota only jetted so tight arsed to keep the economy up, keep the polution down and try and recover some of their lost torque from the low comp anti-polution motor.
