Raider 150 CDI exposed

Raider R150 dc-cdi can rev as much as 13,000 rpm, but when use to other suzuki made underbone motorcycle such as shogun pro 125cc, the performance is almost identical to the shogun oem cdi. So out from curiousity, the cdi internal needs to be exposed, like the one i did to this shogun pro 125cc CDI and to this Kawasaki barako 150cc CDI.

Let the tear down begin


First the case must be destroyed and removed to gain way to the rubber coating of the board as shown, any type of diagonal cutter can do this job.

closer look of the cdi without and removed plastic cover case.

another close up view before manually scraping that rubber epoxy that covers the entire components of the cdi. (this will be needing a huge sign of patience)

After hours of scraping  the bits of broken glass that covers the cdi together with the sticky rubber epoxy, the cdi board is almost expose.

Almost done the top layer of this cdi. If you take a closer look at the CDI board of the shogun and the barako 125, they are almost identical, parts are the same, MCU are the same using the motorola processor, uses the same High Voltage generating circuit, identical capacitor with a value of 2.0uf/400v. all of them has the Tx and Rx port for PC communication that up until now, i have not found any that will be used to communicate. What differentiate this with the other two, this cdi have a TACHOMETER out for the panel. Yes a tachometer signal out for getting the engine revs at real time. Sooner, i will draw the schematic of this cdi.

The three board side by side:


The Shogun Pro 125 has a TPS input pin whileas the Raider 150 CDI uses the same pin but in this case a tachometer out. The kawasaki barako on the other hand is not connected elsewhere.
