Correct jetting for polini177,

What would you reccomend for my polini 177,28mm dellorto,with all the ports matching using a evo exhaust

Check the above site for some ballpark setup ideas. As you know there is no exact setup for one motor and its a case of buying a range of needles atomisers and jets, then following through the 3 stages of carb running setup.

good luck


as base you could try to start the following set up:

main 108
iddle 55
calibrator AV264
needle X2
needle clip position 1 (from top)

you should need just a coupple of different size spare main jet to get it right.
