They don't have advance built in them they have retard built in them.
Junk for racing application.
Throttle response from idle is sluggish.
The flywheels are broached in different locations.
If you put one on a regular flywheel timing will be like 20*atdc.
The coils advance from 10 up to 20*
I see what you are saying, the coil retards the spark according to the signal.
It's is not limited by the rpm, so it keeps advancing,
In this case Joler this statement is not true.
All this begs a question:
Why hasn't ARC or someone else just made a flywheel that will and inboard CDI system off a bike.
There is plenty of aftermarket support for something like that....
Definitely would think the same thing, but the market apparently isn't too big. But it's a huge improvement on the gx270, i can tell ya..
I've thought about this......
You need a trigger and charge system.
Since clones already have studs to mount a 60 watt charge coil, you just need a trigger and CDI.
Of course no one makes a flywheel....
That's the real hang up isn't it?
Damen Right it is.. You Can actually buy a throttle body for small engines, try and google small engine electronic fuel
We once put timing marks on the KT. On the dyno, we checked the timing advance from 10,000 to 15,000 RPM. There was no change in timing across that range. I can't speak for your ignition but the Yamaha ignition shows no degradation at high RPM.The right question might be once you get above 3600 rpm does it start to retard like the older dumb electronics inductive?
