I live in NW Iowa. And 95% of my rideing is ditch banging. I have a 1998 ZR600 carbed. I have added a 136" track with 1 3/4" lugs. My problem (to me) is it does not "launch" till right at 5000 rpms. The problem is not the launch, (which is very fun) but that most of the time a quicker engagement would be more adventagious. My sled has plenty of power and suspension. I would consider it a crossover set up. But I am confused when reading specs set out by retail sites as to which springs to choose. Oh yeah the motor is stock and very strong. It lifts the skis on flat ground take offs. ANY IDEAS OR SUGGESTIONS GREATLY APPRECIATED!!!
