Here is a proven collection of parts, to get your biek up to speed. Includes:
Clutch spring kit
9:1, or 9:8:1 gears
These components will only compliment the Big bore kit you decide to add later. These parts alone will get you close to, or over 50mph on an otherwise stock DIO SR. This is a great first step to get your bike to higher speeds, with only touching the transmission. This DOES NOT require any jetting, or engine tuning.
This CT manifold allows for a bigger carb, and more reeds. Complete with new gaskets, rubber boot, and reeds. Pair this up with a 21-30mm oko/pwk/polini carb, and its game on. This is a tried and true manifold for the dio, from 72cc to 125cc.
WILL NOT work on pre 1986 aero motors. It WILL work on 86-93 afo5e motors, WITH my manifold adapter. This manifold will not work on your 4 bolt bike, without my SSS custom adapter plate.
Simple, and effictive. This a great upgrage for anyone with a stock clutch. it will work awesome on a stock bike, simply needing a clutch, or a built 72cc scoot. This is a really easy install, and you con't beat the price. Limited stock on these kits. This is the FLY clutch
