jetting question on a scrambler 400
I recently rebuilt the engine on my 00 scrambler 400, only mod is a hot seat head, question is, it has a 410 main jet. Does anyone know why such a big jet was installed

Think some one over compensated a bit.. Shows 230 main as stock. If the head is the only modification start out with the stock jet and see how it does. Plug chop it and check the spark plug. Like your avatar as it's very familiar...
