Clutching and suspension work can do alot to make a sled faster, you can find good instructions for the clutching aspect on totallyamaha.com
here are some instructions on how to modify your clutching

Jetting your sled properly also has an impact on power output, here are the stock jetting specs, it is NOT recommended to go leaner than the recommended spec for your altitude/temperature, however many dealers do not set-up the sleds to the conditions of the area they are being sold in. GOING LEANER THAN RECOMMENDED JETTING PUTS YOU AT RISK OF ENGINE DAMAGE AND/OR ENGINE FAILURE

if we could get some charts up for recommended jetting on all the different models that'd be great to, I coulda sworn that they where already on the site, but I can't find 'em for the life of me, Mr.Sled, is yamaha ok with you posting info out of there technical documentation? if so I'm sure someone can scan the charts out of the FSM.
Suspension is a whole nother ball game, for more traction off the line setting the FRA to full soft, loosen off the rear shock and tighten the front shock in the rear skid. now loosen the limiter straps. this will allow more ski-lift but decrease ski-pressure. the shock adjustments will also obviosly have an effect on ride quality. transfer rods can also have a great effect on ride quality, if you intend to play with the suspension aspect I would recomend getting a set of quick-adjust ones, as they are fast and easy to dial in.
