hey all. so heres the story. back in 08, i bought this chinese scooter (honda gy6 copy) by 2009, i was sick of 30mph. so i bought a 72cc big bore kit, ruined the rings and before i had cash for a new set of rings, i got my license. needless to say the scooter sat in about 500 pieces for over 4 years. after realizing that i have to work almost 2 hours to break even on gas to go to and from work, it gave me the push to rebuild the scooter and ride it to work. (and save some wear and tear on the car during nice weather anyway)
sooo. i bought a 100cc big bore kit.
here is a pic of the old 50cc piston in the new cylinder sitting on the new piston.
after rebuilding the top end, i replaced the weights in the variator so the scooter could take off at a lower rpm, also adding a higher top speed. (cvt transmission)
after all that was done, the engine was ready to reinstall.
after that, i fixed my throttle cable with some bicycle brake cable, a drill bit a piece of scrap metal a grinder and some lead. had to make my own ends, because i didnt want to wait on china to ship me a new one that was just going to fail again. (the scooter only has about 3,000km on it. that gives you an idea of why i didnt want to get another cheap *** chinese cable and instead opted to do it the hard way)
before i did this, i had ghetto rigged this thumb throttle out of a bicycle brake handle and some cable clamps. even at age 15 i was rednecking .
after i had the scooter up and running, i decided i could use some tunes for the 40 mile per day ride. -this is where my redneck side comes out-. the pics show the stereo without the glovebox lid. i have since installed it back on.
if anyone was interested, those cheapo walmart "hd" speakers sound fantastic. here is a link to em
after all that was said and done, i took her for a 30 mile ride, and she did fantastic. it hits 50mph on flat ground no problem, and going down a hill i buried the needle. id estimate i hit about 60. needle only goes to 55mph though, so i cant be sure.
ill upload a video as soon as i find my helmet and can strap my camera to it. (no helmet law in indiana).
i prefer a helmet myself because i cant stand the sound of wind in my ears (apart from the obvious reasons) but i cant see dropping another $200 when i know i already have one. its just a matter of finding it after moving 3 times. lol
thanks for reading guys. im pretty proud of my little project. its my first ever engine overhaul. lol
