Sorry if theres already a discussion about this, if there is I searched and can't find it.
Anyway, the Grubee website indicates a new generation of happytimes that appear to make things alot easier.
1. CDI integrated into the inside of the engine, no more dodgey wires and connections outside, and CDI not exposed to the weather. New magneto design. This I presume will be a much more reliable ignition system.
2. New CNS Carb design, I presume no more crappy leaky carbs. No more of that crappy air filter.
3. Larger intake.
4. 202 bearing upgraded to 203 bearing, bigger oil seals.
5. Rear and front mounts wider for much easier fitting to frame. Mount studs upgraded from 6mm to 8mm to reduce instances of thread stripping/over torquing/breakage.
6. New bottom end roller bearing. One piece crank balances. (I recall a thread here about someones balances suffering catastrophic failure)
This milestone marks the first major overhaul of the original design from the Chinese factories.
