Just did a fresh top end on my 89 200. Havi g load up issues going up hill primarily. Thought it was a fuel issue,but after a season of jetting each ride and. Not being able to remedie the problem I'm leaning towards an ignition /spark issue. Not my strongest subject when it comes to trouble shooting. Looked at bike bandids sight to see how much a new stator and ignitor ect would be and its around the 1600 dollar mark all said and done. Any ideas

I can sell you a new adjustable CDI for half the cost of OEM. And there are good replacement high voltage coils on EBay for a fraction of the OEM cost.
before going to all that trouble, first take off your stator plate and remove all corrosion. The metal contacts there are the ground return path for the ignition system. corrosion adds resistance there, making the system less efficient.

I agree with Jaguar. Also, make sure where the coil bolts down is corrosion free along with the short ground wire coming off of it and all other electrical connections. I had a similar problem fairly recently and it turned out to be my spark plug wire so check it as well.

I just posted this in another thread but I found a loose connection screw on the backside of my stator for the black ground wire. Check that connection also.

Downshift??

You may have a customer for the ignitor...

Think mine's dead. Will confirm and order in the morning (assuming you're still making these?)

Had a similar problem on the 500. Smashed a rad in a race and it kept dying at idle and under full load. Thought it was too much fuel loading up from letting it tractor around. Then I saw the rad and thought it was overheating. Turns out the rad was dripping on the coil and started to short. Swapped it out and ran like new.
