Hi guys! I was recently about to re jet my carb on my yamah dt125x and I am 100% sure that the stock main jet size is 210. Once I opened the carb I saw a main jet size 75? It said 75! I had ordered jets from 180 to 290. (Mikuni) and the 180 size was waaaay larger than the existing jet so now I'm thinking how is this possible? Anyone got an idea?
The bike is running great (slightly lean but still very good)
