Like Dan said there's no way to say how many are still around. I don't feel like the 340 version gets "saved" as much as the 440 unless of course it's a Cross Country version.

Welcome!

Also, NOS pistons and rings.

I have an 800 that is almost completely in pieces that I'm never going to finish. I have many, many parts including some new. The good: Everything to build motor Dual Mikuni carb setup included. Walbro as well New studs in track Recovered John's seat New 295/s windshield Skis already blasted/painted...

Try doing a search, I believe this has been discussed before between Peter (That Girl Racing) and Joe Rainville.

No - when you remove oil injection on a Liquifire, you loose crankshaft lubrication as it has lines that go to the crank bearings.

Welcome Cooper,
None of the serial numbers start with 0, the first year of sleds stared with 11,000, so they may have mis-read the first digit. The engines are slightly different models, and there were only minor updates between them.

As many of you know, I used to make calendars. Luke, the owner of New Breed Parts, will be continuing that for 2024! Here is his post copied from Facebook: With just over 2 1/2 months left in 2023 I’d like to announce bringing back an old tradition…John Deere snowmobile calendars! 🗓️ The email addre...

Folks, I have not heard from Gary in a while but I would guess the chance of this going through is slim to none with the state of manufacturing and cost since COVID. If it did go through, I bet it's double the price originally suggested.

TB340a is the free air engine used in the JD Spitfire & Snowfire and also the Kawasaki Drifter F/A. With the CDI/coil combo I believe it may be the Deere version. Deere's last model year was 1984, and I know no other snowmobiles used that engine after that as it was the last free air snowmobile ...

Gorgeous.

I don't know a source - I just have a an NOS Kawasaki one laying around.

No one on this site recommends removing oil injection. I think the steel stock would twist right apart from vibration, that's why they used the spring key. I have one for you. Be sure to test your oil pump first - feed some oil to it, and run it with a drill. You should get basically a drip of oil f...

Oh boy. You might actually get better performance if you can figure out how to fit a stock muffler on there. Highly doubt there is any tuning on that one

The internet says the 7500 was 65hp out of a 340cc. L/C with exhaust valves. Yea, that's gonna be a tough one with anything other then a 1980 Liq.
