Ignition Timing help please

[Rick84KDX200]

I have a 1984 KDX200 and I had to fit a new style flywheel on it. I clocked the original stator according to some photos I found on this site and have my timing light set up for two stroke and marked top dead center but anytime I think I might have it close when I restart the bike again the mark is in a completely different spot like almost opposite where it was. I can keep shutting it down and restarting and it just keeps jumping around the flywheel. Kinda stumped if anyone can chime in that has fitted a E-series flywheel on a 1983-1985 or anyone with experience timing the KDX’s it would be much appreciated!
Thanks Rick

Are you saying the rotor is spinning on the taper?

[Rick84KDX200]

No the woodruff key is in place and flywheel is not moving. I’ve found I can just turn the timing light off and on and it will do the same thing moving the tdc mark 180* out each time. What should my timing advance be set too for a 1984 KDX200? I have it to where it’s showing around 5* at idle and about 25* at 6k-6,500rpm. But not sure where it should be set.

Do you not have the OEM manual?

[Rick84KDX200]

I do not, I was hoping someone might be able to post the ignition timing specs if they had one or the clymer service manual for the 1983-1986. All I have been able to find is for 88 and above when they went water cooled and I feel like that would definitely effect what they had the timing set at from previous air cooled models. Any help would be much appreciated!

Mine is buried somewhere, so I can not get to it. I looked in the 86 and it says 19 degrees BTDC @ 6,000 RPM.

Do you have the flywheel slotted to the correct angle? You are not trying to just bolt on a 1989 flywheel without reslotting the keyway are you?

[Rick84KDX200]

That’s closer to what I was thinking thank you I’m sure the 86 is very similar timing wise, I’ll have to retard it a couple degrees then. As of right now I have it set at 21* at 6,000 rpm. I do have the original flywheel reslotted. It’s my first time using a timing light so maybe it was just user error initially with the timing mark moving around because it’s holding steady now. I really appreciate the help! If anyone does know of the 1984 KDX200 timing specs specifically that would be great but for now I’ll run it at 19* thanks all!

OK, I re-read it. You have an "E" flywheel bolted to the 1984 crankshaft and are turning the stator plate to match up. I finally get it now. Sorry about that. I am getting old in my old age.

[Rick84KDX200]

Yes exactly, no worries at all! Thanks again I really do appreciate the help. I would be lost if I never found this forum!

Thanks, Rick
