I installed it on my FZ750 and was able to experience the effect. The spark seemed to get stronger, so much so that the carburetor setting had to be changed. Pickups from low openings become extremely thick, and it feels as if the engine displacement volume has been increased. The medium opening and above was so great that I became a little hesitant to use it on public roads.
FZ is almost 40 years old, and Ignition coil and CDI are doing reasonably well. I think you will probably find that changing to a new OEM will make a lot of difference. But to begin with, OEM is no longer available. It is not available.
About 60,000 for a new Ignition coil and CDI. It is not expensive at all. I wish I had implemented it sooner." I regretted it intensely (sweat).
As for MODE switching and REV switching, we have not used them yet. The Instruction Manual describes the characteristics of each MODE, but does not go into much detail about what kind of Engine or Setting it is suitable for, so beginners may be a little hesitant to use it. I would like to study the advance and delay angles, etc. before touching them.
The installation can be handled by referring to the Instruction Manual. However, I had to make some modifications.
One is the orientation of the Ignition coil. In the Instruction Manual, the plug cord is routed from the rear side (carburetor side), but this is very forceful because the Left Side goes to the harness and the Right Side goes directly to the WaterLine. So I use Coil as Quantity:Pair (for Left and Right) The plug cord was replaced and routed from the front side (head pipe side). It requires a slightly longer cord, but it fits more neatly that way.
Plug cord is recommended here in Option. https://www.webike.net/sd/21955852/ The connector is already crimped. The bracket of the Uotani is special and quite large, so it is not compatible with general Electric Works Pliers. It is not exactly impossible, but it is difficult to crimp it exactly and neatly.
Next is the with Connector Harness that connects Coil to Harness, but Included Parts:has a very short Harness. It is not impossible to attach, but it is not good for mental health with Tension on Harness.
Therefore, we purchased the Option Harness separately and installed it here. https://www.webike.net/sd/23863361/ This is recommended because it has a longer Harness and more room for maneuvering. *I would rather have this as Included Parts:.
ControllerBody is mounted on the Right Side of the vehicle body. This one has a long mounting harness, so it can be mounted on either the Left Side or Right Side. For now, it is tentatively fastened with Tie Wrap inside the RightSide cowl.
In general, Large satisfied. This price for this peace of mind and performance. It is a great value at all!
