[QUOTE="biglou, post: 153292"] [b]Also-Heat?[/b] Getting ready to open up a CDI from a friends older Yamaha (coincidentally) street bike to look for cold solder joints. He got some info off a site related to his bike (Virago?) and wanted me to take a look at it. I wonder if the heat rising from the motor on the F's is having an effect on the electronics in the box? That could certainly change the characteristics of some of the electronic components if they are not rated to that temperature, whatever that may be after heating up. We will be looking to replace certain components that are not at or above a certain temp rating per the instructions downloaded from that site. As for the shorter kick lever, if I have this correct, the same [i]leg[/i] speed will move the fulcrum (kickstart shaft) at a greater rotational speed, thus turning the engine over faster, providing a stronger spark. A redesigned shape to make this more ergonomical makes sense to aid in the effort. And yes, it would take a "stronger" kick (more force) to keep the same leg speed since you have effectively shortened your lever. I remember kicking over Jason's 426 this spring after a few hours on the DRZ(magic button:) ) and just raising a leg that high after being in the saddle all day will draw your attention to your obliques in a hurry! Of course, that doesn't take much for me.:) [/QUOTE]
