Ok so I have 1 ZR 900 .pro. Well sometime during the season I plan to do the conversion. One thing I am unsure about is the 8" wheel upgrade. What is the real purpose of it and is it needed? Another thought I have is right now my machine has the 1.375 track and I was thinking of using the ripsaw. Most of my riding is trails ,but sometimes we venture into the boondocs and the hills. Even though I will have more track length I was wondering about the scooping power of my stock track vs. the 1 1/2" ripsaw? I would hate to feel like I was giong backwards. Also should I be concerned with reclutching after the conversion?
