I keep seeing people asking about what jet size they need and the recommendations to buy a range of jets.
I picked up the reamer set, because it was so damn cheap, and I think that if I am looking to up-jet something after a mod, Im just going to progressively open the jet with the reamer until I get close.
Yeah, it makes for one mis-marked jet.
After I get it four stroking at WOT, Just measure the reamer with callipers and buy a small range of jets below that.
This is really perfect if your clone carb came with a mystery jet in it to begin with.
They also have a fancy set from 0.6 - 1.4mm for 6x the price.
If you do it right (maybe restrict the intake a bit to force a rich condition) step up the jet until it four strokes and then remove the restriction.
$6, one jet, perfect tune.
Am I missing anything. should we be doing it this way instead of amassing dozens of wrong jets to get one right one?
