What are some more good mods for a 150cc GY6 scooter motor?

by Jeremy
(Logan, UT, USA)

I'm looking for suggestions on how to modify and upgrade my 150cc GY6 scooter. Here is what I have already modded:

  • Air intake is changed out with a sock filter
  • Clutch is changed out with a performance clutch with black springs(not sure on the tension weight)
  • Torque spring is changed out for the hardest spring (silver)
  • Variator has 13gram weights, waiting for my 115mm variator to show up
  • Carb jet is changed out to a #125
  • CDI has been replace with a stage 1 CDI
  • Spark plug is replaced with an iridium plug
  • Coil has been replaced with a higher firing coil
  • Exhaust from the manifold back has been replaced with a shorty ruckus exhaust pipe
  • Head lights replaced with LED bulbs to conserve juice

Any suggestions?

125# jet
by: Anonymous

So i finally got out and tested it this weekend. The overall get up is amazing, but during the winter I was far to ambitious. I believe I modded a bit to much. It still bogs out a little at 50 but getting to that speed is freakin quick. So i will start taking somethings off until I get it right. I recommend the 125# jet for sure.

125# jet
by: Jeremy

I got the jet changed out and re-adjusted the air to fuel ratio but unfortunately got snow over the weekend so I have yet to test it re calibrated. I did get the chance to run it when it wasn't re calibrated and the get up was quick got to 50 relatively fast but around 55 it felt like it was getting to much gas and flooding out.

Have the mods helped?
by: Bill

I was wondering how the upgrades helped the performance, Especially the main jet. I upgraded my air filter but my top end performance is lame. Did the main jet #125 help?

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.
