What does anyone know about old (70 vintage Yamaha's) I was given a old one.
Looks just like a Elan.  It has a 238 twin in it.

I'm not familiar with a 70's era Yamaha with a 238cc twin. In the early 70's
there was the SM292 single, and later the Enticer series had a 250cc single,
and 300cc and 340cc twins. In the 80's there was the Bravo 250cc single. I
didn't think that any of them looked very much like an Elan.

this may even be a sled from the late sixties.  Body wise it is very similar
to the 68 elan / Olympic I had.

The first Yamahas were brought in during 1968-1969, and both years they were
350cc twins (SL350 and SL351). Yamaha stuck with  340cc or larger twins
until 1972 when they brought out a 292cc single. Could that sled you have be
a 338cc twin? That motor goes back to 1971 with the SL338.

Yes, upon closer inspection tonight I discover it is indeed 338,  However
the sled pictured is much nicer than the one I have.  I suspect that years
of kids riding on this sled have taken a toll.  However I think I'm going to
revive it for the next generation to ride

In order to get parts for this sled you're going to have to know the year
and model. As I wrote, the 338cc twins started in 1972 and continued for
many years. I'd suggest using the web site http://www.totallyamaha.com/ for
help with model identification and parts location.

My first new snowmobile was an SL396 Yamaha. The sled was bullet proof and
very well built. A lot of technology for the time, with a lot of that
borrowed from the motorcycle line. I think you'll find your 340 to have
decent power but lack the exact steering and plush ride found on newer
sleds. None of the suspensions on the 70's sleds were overloaded with
suspension travel, and it does help to have a twenty-something back. Good
luck.

I'm hoping this will be a good sled for my thir*** year old.  He doesn't
need plush ride or power.  and may be hard steering will slow him down but I
doubt it

David, I can't agree more with your opinion of older high performance sleds;
they are basicly hand grenades on skis. But, some of the old sleds were
fairly reliable, and the early Yamaha 340's were certainly that. Yamaha
built them like a tank, and they would run for years. In my early years of
riding I owned several Yamahas, and it wasn't until the last few years that
some models were a bit touchy. Okay, my SRX-440 could be a little difficult,
but lots of Phasers, SRV's, XLV's, and ET's were pretty solid.

Just curious, which sled is still being used by your buddies?

In ways it would hurt my feeling any if it was like my 68 Elan and only ran
10% of time.  It will make him appreciate that much more when he can up
grade to nicer sled like my wife's 94' Arctic cat Jag

This sounds a lot like a friend of mine He bought four Artic cat Pumas and
had enough parts to run one
