PERFORMANCE CDI
Scrap that limited stock CDI and drop in this unlimited performance CDI with
no governer, and an advanced spark timing. This will increase acceleration
and top speed by 5-10%, if all else is well. No guarantees on performance
parts as this will not improve power if your engine is not running well to
begin with. This is plug and play for GY6 scooter atv 50, 125, 150 engines
in 152QMI, 152QMJ, 157QMI, 157QMJ, 139QMB 4strokes. If you have this connector
and have an AC fired system, it work. $39

intake manifold will make a market difference in not only overall performance,
but in starting and feel. Flat slide reduces turbulence, impoving reliable
