Hey all..
Had something pop into me head before and wondered what everyone thought.
when I replaced my exciter coil on my stator i noticed my timing was advanced by one notch (there are 3 lines) so i reset it back to factory which is the middle line or notch as said in the manual. When i rode the bike it felt a little restricted but had heaps more bottom end. so i put it back to the advanced setting as it gives me more top end. Is this the right thing to do or should i leave it at the factory setting, and does it hurt anything mech wise running advanced? your thoughts would be great as i am thinkin of putting it back to standard.
Thanks guys.

If I had to guess I'd say thats the difference between the 89 and 90-94 E KDX's. The 89 had its timing slightly retarded vs. the 90-94 KDX's which was advanced for more top end HP.

It really comes down to your preference. If your riding for the day is going to consist of needing lots of lowend, than Retard-needing lots Rev than- Advanced.

Yep the adjustment is put there for you to use (tailor your bike's performance to a degree). If I recall correctly - it is even spelled out in the service manual.
IMO - Too much of anything is not likely always good mech. wise - I view this ignition advance/retard as an indication by the design engineers on what they believed was acceptable range of ignition timing based upon some preset parameters. I've played with the ignition timing a little bit and I think that if your running a rev pipe and want a little more low end grunt there is some to be had. If I recall correctly we changed the main jet one size and got back most of the over-rev after retarding the ignition.

re: the advanced setting as it gives me more top end
That is incorrect.
re: got back most of the over-rev after retarding the ignition.
That is correct.
As long as you're going to be moving things around...maybe start with knowing what said movement is going to effect/accomplish.
BTW...looking at it, the KDX FW rotates CCW. To advance the timing you move the stator clockwise...and versa vicey.
That is incorrect.
