Re: 1980 Spitfire Rear Shock Help

You are correct in your suspicion that the limiter is on the wrong side of the pivot shaft. It should be under the tube, allowing the rear of the swing arm to shift down and toward the rear.

Re: 2026 Ride with the Champs! February 20 - 21

One month out! I have a Liquidator ready to go, but unfortunately my ‘78 Liquifire is out of commission so I’m working on a backup.

Re: Gross-Jet

Are these different than the ones that fit Mikuni carbs? If not, I have a friend that has a bunch.

Re: Ignition boxes.

Good morning. All the Prestolite ignition boxes interchange on the Deere Kioritz’s. The plug styles changed a bit over the years, but you can adapt them if needed. I do want to warn you that many of us have had mixed results with the aftermarket Chinese boxes. The Hewtech boxes from cdibox.com are a...

Re: 78 Spitfire Track

Snowmoer the 81-up cleated Sportfire and Trailfire tracks are actually a little bit wider than the 80-down and DD tracks. They will rub on the insides of the tunnel if you use one.

Re: 78 Spitfire Track

Good afternoon. You can broaden your search a bit. The Sprintfire, Snowfire, 80-82 Spitfire, 79-80 Trailfire and 80 Sportfire tracks will also work on your Spitfire if you find a decent parts machine.

Re: Install tach on 1980 trailfire 340 from cyclone 340

Hi, Deg. The tach from your Cyclone with the Prestolite ignition is not compatible with the Trailfire. Luckily, there are a lot of the Kawasaki powered sled tach kits available. New Breed Snowmobile Parts has them.

Re: JD 300 Starter Issues

When you try to start it, does it engage the bendix? A starter can turn easily on a bench when there is no resistance, but not have enough torque to turn the engine over in the sled. I’m guessing you have a failed winding in the armature.

Re: JD 800 points to CDI Conversion

Steve, the wiring for your 800 should be set up like the 76 Cyclone as far as the engine to chassis connection is concerned. Here is a link to that wiring harness.

Re: Starter Interchangability

Good morning. The starters for the Kawasaki powered sleds interchange. I’m not sure about the jet ski, though. I’ve never looked at on up close.
