Charles Castloo is having electrical problems with his 2007 YZ450F. I reposted this from Mototalk in an effort to help him out.


My 2007 YZF 450 has no fire and I need another YZF 450 around the Riverside, CA area to trouble shoot and figure out the electical problem. I have eliminated the spark plug (tried new and used), the Coil/spark plug cap and I disconnected the kill switch. The way I see it, that leaves me with the stator, the actual wire harness, and the CDI box. I don't want to waste money buying stuff that isn't the problem. I need to find someone that will let me swap stuff on to my bike until I get some spark out of it, then I will return everything back to how it was and buy the needed parts for mine. I would probably just try CDI, then harness, if neither of those fix it then I will just assume its the stator.

Please reply, PM or email me if you can be of any help. Thank you in advance!!!

Anyone else had any electrical issues with a newer YZF 450?

There have been some reports of stator coils failing in the '07's. I suggest he test according to the manual.

One of the guys at Vet-X has been having the same prob with his 06... STATOR. Haven't heard this on an 07 yet. It is a recurring problem. Check with Yamaha. Also beg one of the Yamaha test riders for help.
