this is the first part of me installing a big bore kit i got from my friend Chris on ebay. the kit is 60$ usd, this is a very good deal! in this video, im showing what the kit includes and start tearing down the scooter. to get the kit go to http://www.ebay.com/robotechlegacy/. i am not affiliated with his buiseness, i just got the kit and really like it and highly suggest getting this one! i did the math and this makes your engine about 86 cc's, it will have the power like never before and actually be fast! i recomend getting a 23mm carburetor (maybe 125cc) and a performance muffler to make it flow, or full potential will not be unleashed. i also have one of those orange no-revv limit cdi's. (got for 13$ from scrappydogscooters on ebay, they are also really good). it is also good to get one of those orange high power ignition coils. this isnt step by step, if your trying to use this as step-by-step instructions learn mechanics and get good at it AND know what you are doing before taking it all apart and it never running again. I AM NOT RESPONSIBLE IF YOU HURT YOURSELF, IF YOU GET A TICKET FOR NOT REGISTERING YOUR MOTORCYCLE. ANYTHING ABOVE 49.9 CC'S IS CONSIDERED A MOTORCYCLE, FOR SCREWING SOMETHING UP, OR ANYTHING OF THAT NATURE. WHATEVER YOU DO IS YOUR RESPONSIBILITY. THE ONLY THING I CAN DO IS HELP GUIDE YOU THRU WHAT TO DO.
