You will past any sled with the 700's, however, the gas range bites. You will go 60 to 80 miles before you have to fill them up (especially the sp with its gas tank.). Getting a 100 miles on a tank is very rare. Bring a lot of money for gas, but at least you will be the first one to the pumps. This sled is the origin for my quote "I can pass anything but a gas station." You don't need to add pipes or anything to it, just dial in the carbs and clutches and you will smoke 800's. Even the triple-triples. Oh yes, you can easily see 120+ on the wish-o-meter. Only a timer or a radar can tell you how fast your really going.
Also, it is really easy to drift (power slide) the sled. Just sit low, make the machine sqat, and power through. THe inside ski might lift a few inches but the sled will remain stable and controllable. You will be amazed on how fast you can go through the corners with it.
