1994 xp catastrophe

[blairwill4]

So a friend of mine has been having trouble with there 94 xp. Start button stopped working. Jumped the solenoid and got a nice kathunk. Opened up the motor to find this......

Just by looking at the pictures, it looks to me as if the mag cyclinder ran lean?? What are you guys thoughts?

 

[Dr Honda]

Yep... minimal wash. I'd say it was old, and went lean.

So pieces fell down into the crank and thats all gummed up too. If I rebuild it myself, how much do you think it will run. It has tempo fuel lines. So I'm thinking motor rebuild, redo carbs, new fuel and oil lines, clean the tanks. Think I can get it done for 500 or less if I turn all the wrenches myself? Debating on what to do with the ski and my vote right now is just clean it up inside and out. Fix everything and have a good running ski that we know is reliable for cheaper than buying a running one.

Nope!

Good oem or prox pistons are ~100 ea plus wrist cage and pin. Add cost to hone another 100.
Carb rebuild kit is 50 ea.
the list will continue and continue.

The fastest would be www.shopsbt and get a reman but thats over 1K

At $500 estimate you are probably at about 60% of the cost for a DIY rebuild.

Send it out and get a warranty with it too.

I know thats what sucks about a 17yr ski.
Its not the ski thats worth anything. Its a working engine that will last another 17yrs.

If your lucky and can wait, find another ski w/717 and swap it with the electronics if your hull is mint!

otherwise your going to have throw money into the one you have.
A used 657x is ~600 bucks with no warranty and been used or abused!!!!

Yeah i just looked at fleabay and thats about what im seeing. Ive got a good 717 sitting in my barn but it has questionable electronics. I think im getting a week spark. Even tried trimming the wires.

I read that the 657"X" electronics works with the 717.
There is a difference with rpm and timing but its with the non "X" engine.....
