[QUOTE="Mojavekid18, post: 124075, member: 815"] Well i have been reminded lately that this is a dirtbike forum where i can ask questions so i figured i'd give it a shot. :smirk:. Anyways I am going to try to attempt to do a very minor port and polish on the *cylinder and intake on the kx 125. I have watched a couple videos and get the basic concept, just wanted some educated thoughts/idea's on this. Have a couple questions too. 1. In the videos i watched he used the carbide bits to open up the *ports alot, i don't feel like i need to go that extreme. Could i just use a regular grinding bit if all im doing is cleaning up casting marks? 2. I have heard alot of theory about leaving intakes rough to atomize the fuel better. Anyone have any ACTUAL experience with both smooth and rough intake ports? (I will clean up the casting marks either way) 3. Should i bother getting a sanding wheel for the dremmel? They only go up to 120 grit and to polish i will have to do 220-1000 by hand anyways. Any other advice is welcomed too! [/QUOTE]
