AS for port matching, i am reading up and watchign videos on that right now lol. I might hold off just a bit on this kit possibly to tune my bike a little more and learn some more about it. About halfway through the 2 stoke tuners handbook and learning loads on this site, wiki and forums as well as the many people here that are willing to answer my stupid questions. I was told to get my bike running perfecto before the kit, and im not expert, but it seems to be running 3 times better than before with the new pipe and open carb air intake. I guess it was 4 stroking before at wot but that problem has vanished and it's just a nice rev all the way up to max speed. The carb has been cleaned and im prolly gonna order a new exhaust gasket today for good measure. If i can get it running to where i feel confident in it, i will bolt that kit the day i get it time permitting. Got 4 more days to cram my brain full of moped knowledge hehe.
