500 Two-Stroke Tech

Anybody familiar with ebay item number 231193674648 or item number 370855631588.?
I'm sure my CDI is on its way out, I've a very weak spark and this is the component part I've not changed.
(I'm going to double check my stator windings again)

Do you have an RD or RZ500 RD's had a little different characteristic.
Seems to be the same #231193674648 RZ unit... 1GE-85540-50
I know there are many post on her about RZ350 boxes that have worked out.
I for one like the Zeel...

You can tweak it.
