I had a 1974 340FA. They handled well for that era. Their biggest draw backs were the carburetors and the clutches. When I bought mine new from the dealer they came though with Polaris clutches on the motor. That clutch was good. Then Bombardier had a recall and they sent you their square shaft clutch. It was junk. Ended up using a Comet. Worked real well.
Bringing back good memories looking at that. Lived in the U.P of Michigan on a farm outside Rapid River right on the Whitefish River. Had a 74 Free air 400 identical to this one as well as a TNT 640..also had an old CR250 Elsinor dirt bike. Think it was also a 74 ...of course we had our good ole Honda 3-wheelers too! Between those and my guns, there was a very content 15 year old version of me on that 400 acre farm.
Back in the day my friend had a TnT just like this one. He bent the crank on the motor when the clutch came apart. We swapped in a 640 Rotax from a different sled. Would pull the skis a couple feet off the ground. We were messing around in his driveway with it. He did a wheelie and the track snapped. Wadded up 5 layers thick between the drive gig and the tunnel. Had to cut it out and replace the drive shaft and cogs.
72 400F/A were rare as hell, wasn't forward design motor & had a black mesh screen opening in the hood my bud had one, his dad was 3rd ski-doo dealer in Ont, he also had a 71 250 Elan Blizzard, & a 75 245Rv, I purchased a 74 340F/A brand new back in the day, it ran 74MPH on a track dyno, still have the papers!
@@randyphillips4001 I have owned just about every version of snowmobile Skidoo built from 69 through 74. A friend had an old snowmobile junkyard and i would fix them and ride them. Even have a double track . I got all the F/A 's from a friend thats father did a race team. My family sold yamaha sleds back in the 70's and I had a few of them as well.
That TNT Free Air put me off snowmobiling forever. Everybody who bought one quickly found out they were belt burners. The clutches were no good, I fought Bombardier for over a year, so did my friends. I never bought another new snowmobile again.
Yep clutches were updated to the square shaft. Uncle blew four belts before noon but I never blew the belt. Cure was a shim in rear left motor mount to stop the motor from twisting sideways and exploding the belt. Was a fun sled to drive until fluffy snow would freeze throttle cables ,brake cable and steering to . Fond memories but am happy to just watch someone else drive it now 😂
I had a 73 400 F/A I swapped out the Tilletsons for Mikunis , it just ran really nice all the time after that. It was a very powerful sled for that time.
Yes nice sled. I owned a TNT 440 Fan 1974. Ok some far years from now then, i own a Grand Touring Limited 2023 900 ACE Turbo . New sled. Yes not riding it yet. I just wishing lot of snow .
Had this exact machine back in the day and was pretty fast could beat the 440 F/C TNT's...that seat is not original to that machine it's off of a 73 Olympic...the proper seat should be put on it makes the machine look more aggressive.
Thanks for looking! Yes the family dog got the seat in the late 80s. In time i will have that corrected.. Also i don't think the skis are original, A work in progress. Appreciate the comments!
Arlyn Moen thanks for the reply. I have a Kawasaki t1a 440 with the rare dual carb manifold and it takes hd size carbs wonder if I can use hd 62 or higher! new subscriber thanks!
that motor appears to be similar to the type 377 which has displacement of 368cc they used that motor extensively in the citations owned the citation ss it had the larger mikuni 34mm twin carb and later reduced to 30mm twin carbs in the formula s the bore was i think 61mm and stroke 61mm also the motor was bored larger for the 500 cc models of fan cooled although the 34mm twin carb citation ss was quite fast lots of power that 1974 is unique with the twin tilotsons
truly one of THE best looking sleds ever !..........and quick in its day and for quite awhile thereafter .
Yep i agree!
My dad had a 73 400 F/A and and raced in the stock classes with it and did very well. Great looking sled in its time. Love the orange on the hood.
Thanks for looking.. Yes they were very competitive sleds. I think not only the colors but skidoo produced some of the best looking sleds in the 70s
one of my favorites of the early 70's ! very nice sled !!

Owned one back in '80. In its day handling was way ahead of it's time. Turned on a dime!
Yes, I like the style and colors and handling! (and power)

A pair of Mikuni VM 36 Carbs would make that a very different snowmobile. Tiliston carbs were the weak point on them.
I had a 1972 400 FA from a race teem. It was fast as hell for a 400. I also had a 74 440 FA

Hawsome engine. I love free air engines looking.
The free airs had a look all ther own Thanks for looking!
Nice machine! I had one like yours in 1990. I loved it!
I had a 73 400 F/A I swapped out the Tilletsons for Mikunis , it just ran really nice all the time after that. It was a very powerful sled for that time.
The Tillotson set up on there surprises me to. I know the snow jet (thunder jets ) used Keihin set ups. Go figure??
nice video !
thanks for the memories !
👍👍👍👍👍
Thanks fore looking!

Yep for the time period they really road nice and had great power.
Yes nice sled. I owned a TNT 440 Fan 1974. Ok some far years from now then, i own a Grand Touring Limited 2023 900 ACE Turbo . New sled. Yes not riding it yet. I just wishing lot of snow .

Arctic Cat skis?
Yep, dont remember how those got on there. At least we painted them! Thanks for looking!
Love it...
Nice
Very nice sled, any idea of the horse power?
I think the400s were around 50 hp..
I had a new 74 fan cooled TNT. Piece of junk Square shaft clutch was a joke

Thanks for looking! And the info.
For sale ?
Was that a 1960? double-track in the garage too?
Ha! That is a 1965 rd8 skidoo..Thanks for looking!!
@@travistml When I was a kid we had a 1960 10 Hp Ski-Doo.
Yes, they were pretty plain and simple but tough. We had a lot of fun on those oldies.. (they didn't cost an arm and leg either)
it would have done a lot better on the race track if that dredded merc snow twister didn't come out the same year
Nice Free Air engine.
not really
it has the wrong seat and wrong skis seat is from a 73 tnt
yep , dog ate the seat in the 80s, didn't know those were the wrong skis though, have to look into that. Thanks for looking!!
who cares
Sweet sled!
Pretty fast
