Recommended Posts

is a 142.5 dynojet main jet the same as the stock 142.5 on the bike

yes.

However, the DJ needle is smaller, so the effective size is larger........

The stated jetting is for use with the DJ needle.

if you don't have the dyno jet needle (all you use from the kit) but still want to do the 3x3, a good alternative (though I wasn't happy with it, because I probably didn't have my fuel screw set right) is to run a 150 main (they are "mikuni, small, round" by the way) and a 25 pilot ("mikuni, long, thin") and fuel screw at ??? no f**n idea, check the jetting page at the beginning of this forum
