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.

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.

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.

Thanks for stopping down, Brian. It was great visiting with you and talking about these old junkers!

Yup, just in the LTD 4/6.

Properly designed twin pipes, Kawasaki six port cylinders, Deere heads with combustion chambers cut for proper quench, and Wiseco pistons along with an HSR off an 82-84 will go along way to waking it up. Kelly Voss would be a good person to get some information from as he has done a fair amount of d...

That all depends on how deep your pockets are. Can it? Yes. Affordably? No.

Looks like yours had the added support plate on the rear tensioner bracket that was called out in the racing tech tips.

Here is the final product. Now to wait until next year’s snow…

This weekend I was able to finish up the sled and fire her up. I wrapped the coolant lines to the bulkhead heat exchanger in aluminized fiberglass to prevent them from getting too hot from the pipes. When it was time to run, I primed the fuel system and gave it 4 or 5 pulls. It rumbled to life with ...

Are your tracks the Deere Yokohamas, or one of the Cat tracks that work for this?

Next step was the secondary. This was disassembled, solvent cleaned, and walnut blasted as well. I replaced the moveable bushing, sourced an NOS 38 degree helix, and installed a new plastic bushing. I replaced the buttons and put in one of the blue secondary springs I repopped. Once that was install...

Today, I focused on getting the clutches done. The primary was first on the list. After complete disassembly, I cleaned the fixed and moveable sheaves in the solvent tank. After that, the sheaves, spider, cover plate, and cam arms were all walnut shell blasted. I like walnut shells the best for alum...
