Performance CDI Testing on a Maddog 50cc GY6 139QMB

Back-to-back tests of the blue “Racing CDI”, Glixal CDI and NCY CDI against the stock one. Surprised at the results. Gained 3mph!! and about 1 second quicker on the 1/8th mile. CDIs have never improved performance on my 150s, but on the 50 it actually works.
