Looking For Better CDI - Two Stroke 80cc

[Street Ryderz]

Both stock and aftermarkets have a linear advance curve. Stock being 17*. Aftermarkets tend to vary and are just simple KDX 200 cdi clones.



Homebrew's are the best. This one does not have any advance or retard (flatline) and does 24kv sparks.

Stock cdi's are based at 20 and 25 degrees btdc then climb to 30+ degrees btdc at anything above 8k, the HD lightning or strike start at around 18 climb to around 25 and drop back to around 18 at or above 8k, The super charged starts at 15 climbs to just under 20 briefly then drops down to around 8 at 8k or above and the separate coils put out 42 kv as I've tested all these with a timing light and spark strength gauge.

I'll just leave this here!

That ignition circuit is wrong from the three ignition units I dissected but I guess I'm just wrong like I always am.

How is it wrong?
