Reposted from wr forum ... as I fail at reading comprehension and posted in the wrong forum the first time:
So I drove to Hatfield and McCoy trail system this past weekend intent on riding my '01 yz426f through a couple hundred miles of trail. Unfortunately on the first day about 2 hours into the ride after a quick break to tighten a bolt on one of my plastics, she failed to start.
Plug wasn't sparking so replaced it and still no spark, also with a rekluse clutch in, a pop-start wasn't an option .. ended up taking her back to camp in the back of a ranger :-(
Upon further investigation, found that my ignition coil was running about 2-3 times the spec resistance (which makes sense for why we would occasionally get a weak spark when cranking it over). So now I'm trying to figure out what I did to burn it out to prevent it from happening again:
- I recently upgraded my stator and put on head and [font=inherit][size=1]tail[/size][/font][font=inherit][size=1] [/size][/font][font=inherit][size=1]lights[/size][/font] ... I've run it multiple times since then though so don't believe the upgraded stator would have overloaded the coil, am I wrong in this assumption?
- We had a pretty large group running the trail so we were moving *alot* slower than I normally like to run. My [font=inherit][size=1]bike[/size][/font] was running as hot as it ever has, I read that heat can ruin a coil? Is this something I have to be wary of when running my dirtbike on trails?
- Finally, I adjusted the idle (black twisty knob on left hand side) pretty high after having stalled out a couple times early in the ride. (A rekluse clutch shouldn't be stalling!) I'm beginning to think this may have had an effect on what caused the coil to burn out
