Winter fun - Project “Freedom” 440cc 2 Stroke 1054 Snowmotractor

[kpinnc 12,007]

Guessing that is a "great, great, great, great granny" gear! 

 

But- based on how much engine you're using, it might be in the ballpark of what you need!

I have a car show at Mrs. P’s work place in 11 days.  She wants the Snowmowtractor in the back of Ole Smoky with the magazine articles.  I think I might just piece it together to look like it should work and call it a day!

[Pullstart 62,838]

I found a piece of 2” aluminum tubing to slide inside the heavy pipe that holds the fender on.  A couple bolts here and there and a spit shine and it’s ready for Thursday’s show!

 

 

[Pullstart 62,838]

Loaded and ready for the show!

My uncle sent me these, from the Gilmore Car Museum, not far from here.  How cool!

I can only assume this is probably where the term came from for the more modern Snowmobile....? Super cool setup. I've always loved the videos of those out for tail rides.

This winter the museum had this T running throughout the grounds during their vintage snowmobile show.  The sound was very much 8N tractor.

I just listed this engine for sale locally.  Am I dumb to keep trying the snowmobile clutch stuff?  I have a whole bike frame, electrical, etc.  13k 9k redline, 6 speed, chain drive.  Simple.  Clutch and throttle from the bike, swing arm, done.

And electric start as an option…. …Geesh I think I’m talking myself into this!

My only concern would be cooling. Obviously air cooled like a Kohler, but designed for massive airflow from highway speeds.

I don't suspect Kevin will be sitting still very long when that thing is running!

But they were riding them around a city with stop and go traffic too.

Chain drive it right to that brake shaft.

And factor in colder weather riding… I wouldn’t imagine much issue.  How’s that work with jetting?  Colder= more fuel?  Another cooling feature of gasoline.

The brake shaft would reduce it 4:1 or so, and backwards.  The swing arm from the bike could probably be modified to run a live axle and suspension however.

 

Now, I found proof of the 13k redline thing being incorrect.  But 9 grand is still whipping good.  I could easily stand not running this at 140 mph if the speedometer is close to possible top speed.  A big rear sprocket or a SIMPLE jackshaft could get that to 60-70 with ease I bet.

Oh that's right. You used that older trans. A newer 8 speed would have the correct direction

What about the trans sprocket on there? Wouldn't that would be the rpm to work with?

Gear reduction is honestly the last of my worries.  I guess I need to suspend the for sale listing!  

[Pullstart 62,838]

Well, there goes me purging!  

 

I’ll just go ahead and re-stash all that crap…

 

 

[Pullstart 62,838]

Not much to do waiting on deers.  Looks like a stock front sprocket is 15 or 16 teeth, depending on where you look.

 

I have found as small as 13T.  That’s 15-23% reduction in speed.

 

Google machine says 112 top speed.  That’s 86-97 mph final, tire size not corrected.  That leaves about 30% to take out.

 

it seems a 50T rear is stock.  It seems a 71t from a dirt bike would get me to where I need to be!

Ok. I'm in. I'll pull up a stool for this lol.

Other things have kept me from here way to long.

 Mike!

 

Other things will likely keep me from this project.  I haven’t done much work in my “chop shop” insulated room but I stuck the entire bike in there.  I thought the bike would be a perfect bench to get the engine running.  Some day.

I hear that.

Camp buggy is collecting dust.

I snagged 2 identical basket case snowmobiles with matching tracks.

Thought I would do a half track version WH. That's collecting dust. They are on my someday list.

Farm Show Magazine got ahold of my story!  I wish they would have sent me the article before print to proof read, but it is what it is.

Hope they paid @tractorchick a royalty and didn't just violate her copyright.
