1974 Ski Doo 400 TNT FA

400 TNT FA Ski-Doo 1974 .

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.

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.

A pair of Mikuni VM 36 Carbs would make that a very different snowmobile. Tiliston carbs were the weak point on them.

[wheelie]

truly one of THE best looking sleds ever quick in its day and for quite awhile thereafter .

[josephshields]

one of my favorites of the early 70's ! very nice sled !!

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.

Owned one back in '80. In its day handling was way ahead of it's time. Turned on a dime!

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.

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.

[jimtoke]

had the 440 TNT silver bullet in 73. sharp and fast

[bertrandbegin]

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 .

[stevenpringle]

I had one. Can you still get parts for it?

[jacquesalarie]

Hawsome engine. I love free air engines looking.

[daveforsythe]

Love the classics! Had a 75 GPX 433 fa. Beautiful sled sir.

[darianballard]

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

[stevenpringle]

The driven clutch on ours developed a bunch of hairline cracks starting at the rivets at the centre of the clutch. Kind of dangerous.

[jimscrimgeour]

I had one when I was a kid, l bought it from a friend of my uncle's, he put a power bloc clutch on it and Kalamazoo claws.what a weapon

[bikerguy]

I had a new 74 fan cooled TNT. Piece of junk Square shaft clutch was a joke

[patenglish]

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.

[barryconnors-ms]

it would have done a lot better on the race track if that dredded merc snow twister didn't come out the same year
