Symptoms of a bad coil
I have a 2003 Sportsman 700.Recently when the machine gets hot it starts running like sh*t. It spits and spuders. I have cleaned the carb, new fuel filter and new plugs. It seems to run just fine when its cold but after it gets hot it starts acting up..
I have read that the coils have a reputation of going bad on this machine. I was hoping someone could tell me if this sounds like the issue. If it is the coil, is this a did it yourself job? I'm pretty handy. |
If you lose spark or it starts to spit and studder,then the electrical system is going out and has to be changed from the Ducati system to the updated Kokusan system(flywheel,stator,cdi coil,regulator/rectifier,jumper harness kit and instructions) Polaris kit# 2202602. You have what is called a "coil pack" that is a combination cdi and coil assembly. When this problem first started I was able to get the coil pack,but now its not available. I replaced a couple and then they would come back with the stator bad! Then a couple months later when I tried to order the stator it was changed to the kit! 2002, 2003, and early 2004 units were affected. AND I never received a bulletin about this that I can remember! The cheapest I've found on this kit is from Cycle Parts Warehouse and its about $475! You are the second one with this problem on the forum today! I ended up replacing about four or five kits before I retired! When you look up under Magneto on the website it shows you the kit number it updates to.They still show the coil pack,but they will probably send you the Kokusan cdi which wont work by itself! You might be able to find a used "coil pack" on e-bay,but be careful as they all will go out! Sorry to bring this up to you,but this is the problem! OPT

I'm not sure if I'm losing spark. It just runs real crappy when it gets hot. I also noticed when I changed the plugs they were all black...I'm assuming from running lean.
Is it a pretty straight forward job to change it all out? |
You may be running rich. You may have a carb problem.
