I also have a 48cc Starfire GT-2 grubee motor from 1-15-09 and was bought from gasbike.net. So i went and looked at my magneto,well guess what it has 6 holes and i do have pics.
Pic 1 is a mag from thatsdax/ pic 2,3,and 4 is my mag, even tho the pullstart is in the way, you can still see the 3 holes on top and bottom and looks the same as the replacement ones.
If you have a diffrent mag you will need to take a pic and show us.
