well, thanks for all of the replies. I really was not sure what all had to be sent in to be ported, but thought if i could just send in the head then i would do it, but to send in my engine is undoable. Since i'm living in the middle east that would mean 2-3 weeks mail time just to get the engine there, port time then anywhere from 3-6 weeks to get the engine back. That's just not a possibility......its prime riding season right now and i'm not wasting it. I have the 13:1 piston on order and will make due until i have a chance to send the engine in. maybe during the summer when it's too hot. This is about the last possible mod i can think of for my quad so I'm content for now, but I definitely want it done.
