not much you can do with that sled man. in top form it will probably only do about 65 maybe 70. it's a good reliable sled if it's in good condition but not much power. i think it only has something like 40hp.

i don't think anyone ever made a pipe for that sled. you can mess with the jetting a little. but air cooled sleds can't run too lean or they'll burn up. you could change the gearing a little to try and get a few more kph out of it but at some point you'll run into the power limit of being able to hold the rpms up with steeper gearing.

what you should do is find out what the stock clutching setup is, then at least make the clutches as healthy as stock. if it's like a lot of older sleds the internal clutching components are quite likely beat.

I think its a waste of time and money to try and make the 340 any faster - if youre new into the sport - at least ride it for a year and learn what the sled can do and cannot do. Once you get the experienced, then sell the 340 to upgrade to a bigger and faster. Ive seen new riders buying a sled thats too much for them and end up getting hurt. We need to keep our sport safe.

Found some money? Like what? 30 bucks or 30 yens? Youre not going to gain a lot to put on aftermarket performance on a 340. If anything, save your money and sell the 340 and buy a liquid cooled. Ask your fellow Canadians that stole sleds for a living. Im sure you can find a nice, cheap sled for you to ride for the year.

Here's a story for you guys...
About 1974 or '75, I was 10-11 yrs old, my dad picked up a 340 TX from a guy that worked for Polaris up in Roseau MN.
It was an air-cooled, modified sled with twin straight pipes coming out each side of the hood.
This thing was loud and it would FLY!
It had been modded for the Winnepeg 500 (the old snowmobile race from Winnepeg to Minneapolis).
Man, I had that 'ol dream o meter wrapped up to about 90 a few times. Of course the old man didn't know that.
Anyway, I think some sleds can really be "sparked" with the right guy and knowledge.

I put a few thousand miles on it and I do miss that sled.

And dont forget, the TX has a bit more hp than the fan-cooled 340 version and two - we all know the dream-o-meter was way off. Not to be a jerk about it - I love the way the TX looks and in fact, I am looking into buying, either a '78 or '79 TX-L340 on Friday. I always wanted to have one vintage sled. WL.
