I don't mess with carbs so I would have to take it to someone for jetting. Everyone says its real easy but I find that many people spend tons of time discussing and changing jetting and still not getting it right.

I am trying to avoid putting too much money into the 250 if in the end, I still have to sell and buy a 300. If the mods are inexpensive enough, I would consider.

Any particular head mods you can recommend?
