i have weak spark on my 85 200s, always have since new. what would cause this?
can barley feel any thing, barley a tingle. or are they all like this? THANKS

 

anybody on here anymore?

 

what do you mean that you can "barely feel anything"? do you have a manual? try this sight for 1

i mean when i take the spark plug out, i hold the plug wire and pull the starter rope
and feel just a little tingle.

 

well i never tried to test spark by "feel" ... does the trike run ? like i said before down load the manual and you can check it by that

 

I've been bitten hundreds of times by these and while they are a bit on the weak side by pulling the recoil starter, it's a whole different story when it's running at RPMs.

If it is indeed getting a weak spark there are a few things to look at.

First is the ground wire that attaches to the coil. Loosen the bolt and move the wire end a bit to "clean" it and then retighten it.
Then inspect the plug wire for any breaks or cracks.
Then get your manual and do a spec check of the stator.
Then an air gap check of the pulser rotor. (Its behind the CDI cover on the head).
I would say the issue is not going to be with the coil or CDI box itself as I have never ran across any that were "weak"...just good ones and bad ones are all I have ever found.

If all checks ok and you still think you have a weak spark and it's causing starting problems, you can bandaid fix it by closing up the gap on the sparkplug a bit to make it easier for the spark to jump the electrode gap.
Hope this helps.

 

i have cleaned and adjusted every thing i can with know help. these things just dont have any spark on them i guess. my dad STUCK HIS TOUNGE THE THE PLUG WIRE AS I PULLED,
and barly felt any thing.

 

well after that fail proof test i pretty much cant help ya dude

 

what i dont understand is how does this thing run with weak spark .
it runs fairly good but fouls the plug out pretty quick, and some time hard to start.

 

I would go back to the basics... Pull the flywheel, clean the magnets, check the air gap to the pickup coil, clean the area where the secondary coil is grounded, make sure the engine is grounded to the frame properly, and if everything is ok, test or replace the secondary coil..
