So as some of you may know my bike wouldn't prime the fuel pump and then I took it to a shop and they bypassed the fuel pump relay and now the fuel pump turns on but stays on. so they told me to buy a new new relay so it will just prime and not stay on. But now the bike still won't start even with the fuel pump working. They said it doesn't have spark. What's going on? spark plugs look great almost look brand new, tip sensor is bypassed and works fine, kick stand, clutch and other switches are intact and work. So what could it be? and if any one lives in the North Bay Area Santa Rosa, CA area and wants to take a look and help please be my guest. Thanks

 

im having the same exact problems and i believe its the diode in my ignition. the pink wire was getting 12v instead of 9v so im replacing the stock zener diode with a 5.1 zener and soldering in a 1k ohm resistor which has apparently worked for a lot of people. If you have a volt meter take out your ignition switch and measure the voltage across the diode if its 12v you blew it somehow and need to replace it if not let me know if you find something else that works because id be more than happy to try it on my bike as well.

 

Thanks. I'm gonna try that today and i'll let you know. And I'll keep you updated on other things I may find.
