I really thought this was a tech forum.

MX tech talk / KTM 530 E/XC died, no spark
« on: November 28, 2017, 04:19:31 PM »
Just in the beginning stages of troubleshooting but my 2010 530 E/XC died out when I was on the throttle the other day. No warning, never had problems in the past, hadn't been riding very long that day, it had been shut off and restarted several times, it wasn't super hot or anything, but I don't seem to be getting a spark.
I already went after the low hanging fruit. Tried a new plug, checked the kill switch, ignition button, key switch, charged the battery all the way up. It turns over, has compression, getting fuel and all that. I pulled the plug, grounded it and hit the button, and see zero spark.
I read some on thumpertalk and a few guys talk about the crank pulsar or whatever (it seems to have 3 or 4 different names). What I can't really pin down is a solid procedure to check ignition components. What the resistance should be from where to where, where to read what, etc....
Anyone have some insight before I roll the dice on what to replace first?

MX tech talk / CR450 head question
« on: January 28, 2012, 07:08:26 AM »
Are there any differences between an 04 and an 06 CRF450R head? I might want to put an 04 head on an 06 if it's doable.
