Hi, Jprigsby to find the source of your oil leak, start at the point where you see oil and trace its path going up and forward, blowing baby powder from the palm of your hand will help in those difficult to see areas if there is too much oil present then buy a spray can of engine degreaser apply it to the affected area then rinse off with a pressure wand or garden hose, use compressed air to blow off excess water or just let it drip dry, take your bike for a 15 minute ride and check for the leak.

SOURCE: i have just brought a new cdi for my 50cc scooter

ISorry m8, no scooter expert but ive changed a couple of CDIs on Italian Scooters and they are a simple plug-in as on any size bike. They are usually found down near the battery, just unplug the old one and pop the new one in, there should be a retainer or something to stop it rattling round.
Sorry i can't be more use.

SOURCE: cant get my 50cc scooter to fire up-no spark. any

  • Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Is the handlebar kill switch on? Is it shorted out?
  • Check the fuses.
  • Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires?
  • Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing.
  • If still no spark, get CDI system and coils checked at the dealers shop.

Hi and welcome to FixYa,

Initially, a couple of checks:

  • is there sufficient compression - compression test;
  • is there suction - cover the carb in port with the palm of your hand, when starting, it should be wet with fuel;
  • determine if fuel is reaching the sparkplug / combustion chamber;
  • condition of the intake reeds;
  • excess 2T oil in the crankcase - clean, air dry.
Good luck and thank you for asking FixYa.
