    It was the coil!!!

    First coil I've ever had go bad on me. Apparently it is a known thing with these KTMs. I'm just happy to have finally resolved this friggin' sporadic issue I've been chasing for months. The bike has all new fuel filters now though (its had two!) and fresh spark plug (friggin' $35 plug! ) and spark plug boot as a result of the diagnostic efforts, so I guess that's a good thing to have all that freshened up. But frick, it sure has been a frustrating journey to get this thing back to running right.

    What's so special about the spark plug that it justifies $35?

    Re: It was the coil!!!

    Glad you figured it out... were you able to test the plug or was it just step by step narrowing it down with parts?

    might be a surface gap plug ?

    Frick, I don't know. Even the local dealer was shocked at the price when he pulled it up and knocked 10% off just because retail was so ridiculous. KTM markup I guess. But I've heard that the plugs for the Honda CRF 250s are stupid expensive too. So who knows.

    Typical trial and error approach given that it was one of those "could be fuel or ignition" kind of problems. What finally lead me to the coil was it started running bad after continuous high rpm operation when on the highway that was resulting in serious cut outs. It wasn't happening on the trail when the ignition load was varying greatly. Hard starting has been in the mix as well, which also was getting worse. It originally behaved like a fueling issue, which is why I started changing fuel filters.

    Once I installed the new coil it was amazing the difference. Even the exhaust note was deeper and stronger. Clearly it had been operating on a terribly weak spark. Well, clearly once it became clear that is.

    Re: It was the coil!!!

    which year and model KTM is it?

    which plug is it? Did you look for alternatives?

    How much was the coil - afraid to ask given the price of the plug LOL

    It's nothing magical. Just typical dealer bend you over pricing. It's just frustrating how dealers can claim retail and sell items at twice the price you can get online through other sources. And dealers can't figure out why they're struggling.


    I rolled the dice on the coil and picked up a used one via eBay.

    We used to pay $54 for Cummins spark plugs. The parts guy found a non dealer source. Champion

    Re: It was the coil!!!

    If the overpriced plug was a br8ecm, a standard br8es can be used. The ECM plug is shorter from the threads up and is easier to change with the tank on, but the full length plugs work fine and can be had for about $3 at oreillys

    Edit, I re-read your post and saw mention of fuel filters, so I’m guessing you have one of the FI 4T bikes, so disregard....the br8ecm is s 2T plug.
