I have a '79 TF 440 I was looking to get out of the garage. Has new Cdi and coils. The sled runs but needs new recoil rope and carb cleaned. No windshield and has some cracks in the fiberglass. Track was replaced a few years ago and is in good shape. Will post pictures as soon as i get them. $300 OBO.

Got the first decent snow last night, since I got my Trailfire running. I was out driving around a field and went to cross a patch of ice. I was going about 30mph. Turns out the ice was a little thinner than I thought. My front right ski broke through and snagged in the ice and dumped me while flipp...

Got it running!! Bought a kimpex cdi off ebay and put it on last night and it runs great now, but I wish I had some snow. Thanks guys for the help.

Sounds like it might be your stator coils. Here is a diagrahm with the specs, try doing an ohm test to see what kind of reading you get. Click on the image to magnify it.

Does anyone know a good place to get a cdi?

I was also wondering if a cdi for a 1980 Trailfire would work on my '79. It seems like it should, because I thought they have the same engine.

With the red wire to ground, I got 141.2 ohms. Starting to think its the cdi at fault. What do you think?

Ok. I checked the pulsar coil and got a reading of 21.8 ohms. Is that good?

Does you JDX8 have an aluminum tunnel? If so it could be welded and it would not look to bad and it would be cheaper, but depends on what you want.

Ok. I have an ohm meter I just havent checked that yet, I am not to good with this kind of electric system, so I wasn't sure.

Thanks for the help Matt, I did a continuity test the other day on the wires for the pulsar and exciter coils and found that they are grounded is this a sign that they are shorted?

Thanks Matt for the info, but do you have to remove the engine and flywheel to do the tests or can it be done by checking the exposed wire leads? Also do you know how to remove a stuck clutch from the motor without damaging it?

Thanks Jimmy, I got the hewtech link to work through the 295s page. I am going to do an ohms test tomorow and hope to figure something out. let you know how it goes.

I Thought maybe it was, but figured I would let you know.
