Thanks, ***** ***** back to my office.

So we are on the same page;

Engine will not start, correct ?

Engine turns over with the electric starter ?

Have you checked for spark ?

Are you still using the stock ignition witch ?

How many miles are on this unit ?


Customer: replied 2 months ago.
The engine turns over won't start we have check for spark it happened right after we changed the forks on the bike
Expert:  Kenny O. replied 2 months ago.

OK, so do you have spark ?

And is the stock ignition switch being used ?

Please answer ALL my questons or this is going to take a VERY long time !


Customer: replied 2 months ago.
No there's no spark and yes it's the stock ignition switch and no we didn't unplug the ignition or anything like that when we changed the forks
Expert:  Kenny O. replied 2 months ago.

OK well that's good, I want you to find the plug from the ignition switch and where it connects to the main wiring harness, you need to check the connection on the gray wire on both harness side and ignition switch side, look for maybe a pinched or bro***** ***** in the area around the forks since you were just in that area.

Also do you have a multi-meter ?


Expert:  Kenny O. replied 2 months ago.


Customer: replied 2 months ago.
I have a multimeter I'll check the wires right now actually the motorcycle agent Linus my buddy but I'm sick of hearing him bitching about it not working so that's why I'm trying to find out what's wrong with it also why would it throw a code 13 saying is the air box sensor that's weird isn't it and he replace the air box Sensor
Expert:  Kenny O. replied 2 months ago.

Yes not sure what code 13 is all about now, that isn't going to kep it from starting and no spark.

So check the connectors like I said an inspect that gray wire especially in the area you were at. Then if that all looks good at the ECU find the gray wire and then positive (+) meter lead on the gray wire at the ECU (probe the wire at the connector) and then the negative (-) meter lead to the ground (-) at the battery, while observing the meter then turn the key on and measure the voltage on the gray wire.

Let me know what you come up with ?
