What! That is great! Do you have any more details on how it works?

I like the 7 segment display startup animation too.

Not really sure but the thing eliminated the need for a CDI, ignition coil and high tension cable as they are all bundled up into one device. It came from a Toyota Vios. aww

 

Ohh you mean the voltmeter? It's really useful 'cause I can tell right away if there's a problem with the charging system which has been plaguing my bike ever since. no

Your bike looks like it's an interesting colour, do you have any photos of it?

I would assume the 3 wires into the cap are... power / earth / signal...
but where dose the advance curve come from... built into the cap if so
is it 100% correct for the TTR...

So meany questions....

Ah yes the Koso EVO 30mm carb. It's pretty awesome.


Hmm I don't know about the advance curve and stuff though he did try a couple different CDI's and probably tweaked with the timing quite a bit before getting good results. :D
