Ive had a ('91) ZX7 for almost 10 years. I bought it as a salvage, and rebuilt it. Never did feel totally safe on it, as there was always something wrong w it. Antifreeze leaks (THAT'LL make you fill your shorts on a turn), slipping chains (yes, I said slipping), crappy carbs, head shake, and the list goes on. So I never really felt safe even remotely "pushing" it. I finally got a newer ('06) ZX10 this year. Finally feel safe riding now. Now, I plan on going to either Putnam or Mid Ohio this year. Ive been to Putnam, but only as an observer, while a friend rode my ZX7. (I Didnt have leathers or the funds) Problem Im facing..... Do i take the ZX7 and not feel safe (and do as much as I can before I go to make it as safe as possible until the next "issue") or do I take the ZX10 and feel totally safe? If the ZX7 goes down, its not a huge deal. Its an older bike and I wont be heartbroken if it goes down. The ZX10 is near flawless, and I would HATE for it to go down. How routine is it for riders to go down on the track, esp as newbies? My friend went down at Putnam when riding my ZX7, so Im inclined to think its not that uncommon. (Only broke the clutch lever) Thoughts? Tks
