Post by JWentworthDavid, 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?
I think the TX is the only one getting used, my buddy's kids beat on
that.
But, I don't think it has anything to do with "hi-performance" or which
models were reliable when they were reasonably new. The problem is that
sleds that sit for years, maybe 10+ years at a time have all sorts of
problems with dry rotting and rust in bearings. The worst thing is that
bearings that get a little rust in them don't fail right away... it takes a
while, so you might get a ride or two in before everything starts to seize
up on you.
The TrailTwister blew out 13 of the 26 molded-in track cleats the first
time I rode it.
The freshly rebuilt SRX ran great for about 6 miles before it smoked
another piston, apparently the stator or cdi is bad... which is why it was
apart when it was purchased. Unfortunately, that didn't show up on the
warm-up stand when he set the timing.
The 340 RV hasn't seen snow yet... the entire rear suspension had to be
rebuilt (all new bearings, wheels, cogs, shafts, swing-arms, shocks, track,
etc); even though it was supposedly "running" when it was bought. It was
probably fine when it was parked... but it sat a long time without being
ridden before it was sold.
