  • @mac83194 just got the gy6-80 engine yesterday there back in stock. Seems pretty simple to replace. I got a cdi from them though and I herd on a fourm that scooters can throw AC current or DC current.any one know the answer?

  • @lHlEIDLEBAUGH it's VERY simple to tell.....look at your new CDI......if it's no bigger than the palm of your hand it's usually AC fired......if it's HUGE......like from the base of your hands to lets say the middle of your middle finger.....it's DEF a DC fired unit

  • is this pipe for all 2 and 4 stroke scooters?

  • @Mzahaka1313 4T scooters only

  • how much more mph did this add to your top speed and where did you get it ?

  • @scootersmithy94 well it's all relative to what else you do.....if you upgrade the exhaust then you also need to re jet the carb.....and if you do that you might as well replace the CDI, coil, and the air filter.....got about another 5-7 MPH with those upgrades

see all
