Is it a good engine? It was never in any Kawasaki sled, or ?

Thanks!

HI Magnus...

I am restoring one (complete overhaul... new crank, pistons, rings, seals, you name it). For what is worth, iwasa having a lot of difficulty findin parts at all the usual sources... that said, I was informed by someone at Als Snowmobile that he KAwi 340 Invader (78-79) is th esam eengine... not sure how that helps you???

Since them, I've gotten a few engine parts that are speced to the invader (such as pistons) and they appear to be an exact fit/replica....

Anyway... like I said... for whatever it s worth.

Hoping to hear this thing run sometime this winter...

Dan

Ive got the free air snowfire (same sled only not liquid) and its a little screamer. the sled itself gives an excellent ride .. only draw back is that its a bit tippy when you drop a ski into a rut but beside that its great for the trails.

Hi Guys,

The 340 Invader is a T-7 Motor, very much like the 80-84 Liquifire 440. It has VERY little in common with the Sprintfire. But, the Sprintfire is in fact a compbination of T-1 and T-7 parts, plus unique block, crank, jugs and head. Cool if the pistons from an Invader fit it, but the factory pistons I think only had one ring for the Spint, if I remember correctly. It also only has one bearing in the center of the crank, allowing for a very compact little motor.

Some Kawi motors that don't seem related do share some parts. For example, 340 Trailfire's share a piston with Kawi 340 F/A powered Spit and Snowfire's for example.

Also, remember that not everyplace knows Deere's that well. I had an add looking for Dator pipes a few years ago, and a guy from Al's e-mailed me and asked if I had a typo in my ad, because he had a Liquifire pipe he could sell me if that was what I really meant. He had never heard of the Liquidator...

Have fun guys,

Dan, just was wounding if the Invader pistons worked in the Sprintfire rebuild? I'm not rebuilding right now, but I have one and would like to know how it turned out.

Thanks, Nick

:huh:

IT worked out great... I posted a few pics previously (all in the the shop) since then I had my inaugral (sp?) trip to the lakes in NH (4 trip sto NH, 4 different deeres) and it was great. Probaly put on about 30 - 40 miles... still awaitng speedo cable, but that is a good guess. Had it up near 50 (based on someone riding next to me)and there was some room left... started 1st or second pull all weekend... best rebuild/project sled I've been invovled (so far)... although I am smitten with some of the late 80 LF.

As this was a LONG project, I recall numerous problems fidinging parts and I only scarecly remember the details.

I talked to Scott Brie at Al's Snowmobile, he's the one that told me they "should work" and when I got them, they appeard to be an exact fit. Again... from the 50 total miles I logged this year, it ran fine...

Not sure this helps at all.

Also folks, the pivot bushing I got (two per side 1 inch long, 5/8 OD, 3/8 ID, grinded down a smidge to give total 1 15/16 ... that worked great as did the nylon bushing I installed on the spindles...

Meant to take some photos in action..maybe next year as I am hanging on to this sled. BTW - the group of us (10 fisheman) iced 40 lakers in a weekned , plus another dozen salmon and rainbows. Good time. Thanks again everyone.

Dan

Is there a certain year of Invader you order the pistons for, or does it work from all years of Invader? Just doing my home work before I ever get in to a rebuild situation.

thanks Nick

Wont the trail/spit pistons fit the Sprint then aswell??

Also, were do you guys get the headgaskets?? I have all except the two that seals the compression off..., not so keen on reusing them....

Thanks!

The Invader uses the same exact pistons as the Snowfire and Spitfire. They will work in a Sprintfire, BUT, the Sprint was a cast bore. The Invader pistons you installed were designed for a chrome bore. They will work but the life expectency is SHORT, expect 400 miles MAX until meltdown. So enjoy your rebuild because it is short lived. Al's gave you bad info. I have a run of Sprint pistons being made they will be available in late June or early July.

See above post regarding the pistons. I have gasket sets available as well as any individual gaskets you might need. Shipping to Sweden isnt a problem.

The Invader used the same pistons in all years, they interchange with the Snowfire, Spitfire, and Trailfire. So any of these applications are the same for all model years, BUT - I would not suggest installing these pistons. I can attest personally to the miles until failure as can Ed Poets. 400 miles and your back to square one.

So why not use the invader pistons with the correct rings for cast bore?

The Invader rings are not for a cast bore, they are for a chrome bore. They will wear out in no time. Cast rings are different than chrome rings, it's no different than installing cast rings in a chrome bore. The rings will destroy the bore in no time.

I realise that but why not use a set of rings for cast bore?
