bigger jet or bigger carb
 

bought a stage6 for my minarelli but haven't rode it yet.i was wondering if I would get more performance out of a bigger carb.if its alittle its not worth it.i know I should go bigger on the main if I stick with the stock carb

as long as you have a performance exhaust go with a big carb, makes a huge difference on a 2 stroke, try a 21mm oko

Either 4T or 2T you really can't go wrong with a bigger carb. Just use the right jet sizes to keep tuned at top end
