ok, i gave my cylinder head to my best friend this weekend because he does port and polishing on cylinder heads all the time and said he would do mines. now, heres the question, will i really feel much of a difference from a good port and polish? also, i am in the process of finishing building up this motor and was wondering what suggestions on carbs u guys know of? i want something that will give me some more power because i dont think the stock carb is liking my aftermarket cam.

 

First of all Yes you will notice the difference, I speak from experience! What did you bump you compression to when you got the max over-bore (or are you talking about the other trike?)? The best carb to use is the one off the XR200R dirt bike. To know the details of this you will have to ask "KNOWSALOT" in the ATC forum. What cam did you go with?
