I know the jets are interchangeable with the Dellorto ones. I'm thinking about getting a range of jets (~10) to try and get this thing tuned right. What range would you guys recommend getting?

Oh, and what is the stock jet equal to?
 
Thats great guys but Dellorto (Italian) jets are metric, as are Mikuni or Kehien (Japanese) and the HT carb is a metric piece as well.

You cant order Dellorto jets by drill number or thousands of an inch.

Order your jets in a range from 60 to 70, thats 0.6mm to 0.7mm, the stock jet is 65 or 66.

Be sure to get originals, the knock-off ones are "kilometers" out
 
as venice stated a 70 71 work great i've been having great results with the stock #70 but i dont run pump gas and have tons of mods to my engines
 
#73 is where mine ended up working great, my engine is the 6mm stud engine which I think is only a 60cc instead of the 66cc, nice med. brown plug color and runs out like a champ for almost 300 miles now, have made some 15-25 mile trips and ran it at close to WOT the entire way without a single problem.
 
Metric vs. standard is a moot point.
metric value/25.4 = standard
standard value*25.4=metric
No big deal.
