ktm 450 exc 06 weak spark

courtneyd · 04-23-2010, 07:26 PM

hey my problem is that i have a very weak spark on my bike and the only way i can get it started is by kicking it and winding over the starter motor as well and even that doesnt work very often. i have replaces the coil and the spark plug so that is out of the equasion. i tried a cdi off a mates bike and no change so that is also out. the only other option i can think of is is that the stator has shat itself. the problem is worse when the bike is hot too if that makes any differance? so i am wondering if anyone has the testing specs for the stator. we got it tested at a motor rewinding shop and he said it was testing at 15 ohms.
thanks

I am not familiar with the '06 bikes. Is the spark plug cable separate from the coil?

im not sure what you mean? the coil has 2 wires i think going into it and then the big spark plug wire comming out of it with the spark plug boot on it

Is the wire with the boot part of the coil (one piece), or is it like a car that
you can change the spark plug wire?

nah mate tried everything therre too but forgot to say it. cleaned up all my earths and connectors and also tried the kill switch trick but none of them help. thanks for the help but i might just buy a new stator if noone knows the testing specs for it. pretty pricey at $700 AUD so might have to go with a trail tech or something similar.
