Info Manual

We all know Suzuki Raider both 125cc and the 150cc version do not have adjusting nut to adjust the valve clearance, but instead a SHIM is inserted and used to vary the clearance between the valve and the cams. Shown in the photo is the table of the shim selection for the raider, satria series of suzuki.

Upper table show the intake side



Lower table is for the exhaust.

Making modification on raider R150 electrical is difficult without the right electrical diagram. All bikes have a color coded wire for easy tracing when doing electrical works. Prior on my post with the FL125 (shogun electrical wiring diagram), in by request, wanting to have the diagram of raider r150.

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.
