I just bought a 2005 ZX6R for my son, I knew it had a bad motor when I picked it up, I'm wanting to find a complete running motor just to get it going for him. My plans are to build the bad motor over the next winter with some performance upgrades. Is there any other year models that will work or should I just stay with the 05-06? If anyone has a complete motor please let me know, he just got his Driver License and will be stepping up from a 250 ninja, he's really excited and can't wait, lol. I just joined this forum so I can't post in the classifieds yet, would someone post for me that I'm looking for a complete 05-06 running motor? I really appreciate any help or suggestions, I have some extra parts for this motor I would do some trading on a motor or sell to put towards a motor, I have a good complete head with everything, a set of cases, good crank and rods, and miscellaneous motor parts.
