I am putting a techno boss exhaust and a hi-flow air filter on my maxi, what size jets do I need for the carburetor. Also, is there a tutorial on how to upjet because i couldnt find one in the wiki.

turn off gas, remove carb, remove the bottom of carb (float bowl) see brass "screw" should be a flathead. take out, replace, reverse steps. go forth and prosper
Trial and error..there is no magic number.
Ok i have no idea where to even start with ordering these though. Do i need to order many different sizes and then just guess or is there a better way
You start with a jet that's a few sizes larger than the jet you have now. To find out what jet you have now, you'll have to take apart your carburetor and look at the little number stamped in the jet. If it's, say, a 56, then you could order jets like, 58, 60, 62, and maybe 64. Then when your jets come, start out with the biggest one you ordered. If it four strokes and fouls plugs, put in the next smallest jet you have. Keep doing that until your plug chops come out looking right.
As for a tutorial, there isn't one on upjetting specifically (that would be a good addition though, now that you mention it). However, there are videos linked in Fred's Guide about how to take your carburetor off the moped and clean it. That might help give you a better idea of how the parts come apart and go back together.
just what i was looking for thanks
