how big is a rm 85 carb i have one and im thinking about putting it on my pitster pro
dood said:I thought those where a Mikuni TMX28 but I could be wrong. Either way most 2 strokes come with 28mm carbs. Either Mikuni TMX or Kehein PWK
You'll have to change the jetting quite a bit for it to work since you aren't running premix though it.
