How can you tune up your vintage sled?

I was wondering if there is any way to tune up a sled without putting on any extra stuff. EX, run it richer or makeing adjustments to the carb. Particularly on a 76 STX 340 round slide kien carb or an 86 Bravo 250, or if you have information on any other snowmobile you have tuned up yourself.

1979 yamaha STX 340

Right now it has a round slidde Kien carb and along side the tunnel it says STX. All the decals are faded and worn so it probably is 1976

1979 yamaha STX 340

I seen a couple of websites that says my STX can do 90 MPH! Mine currently only can do 60MPH. Does anybody know of it will do 90 or whats wrong with it, if anything. Also does anybody have advice on hoe to tune it up without putting tunned pipes on it.
