06 CBR 600F4I Hard Shifting

Hi everyone. New to the forum, and a first time bike owner. Last week I purchased my 2006 CBR 600 F4i. I live in Louisiana, and found the bike on ebay. It was located about 20 miles out of Nashville, so I flew to Nashville, and drove the bike home. 530 miles..Long ride, but not nearly as bad as I was expecting. Smooth riding bike, and fairly comfortable for such a long ride.
The bike only had 946 miles on it. Runs great, and i'm very happy with the bike. The only concern I have is with shifting through 1st,2nd, and 3rd gear. ( shifting up or down ) From a stop in neutral, down to first, there's a fairly loud, and rough feeling "clank". And when shifting up to 2nd, and 3rd, I get the same clanking sound. When shifting down, I can "feel" a slight "grinding" in the shift lever, and the clanking sound is much worse when shifting down. I've tried shifting at different speeds,rpms,less clutch, more clutch, and anything else I could think of. I have noticed that with more riding and practice, shifting up has become smoother and more natural, however, I can't figure out how to resolve the nasty sound and feel of shifting down when slowing down and/or coming to a stop. Is it me, or the bike? Any tips? THANKS GUYS.

I have an '06 also. I would check the clutch freeplay and make sure that the clutch is releasing fully. Make sure that the shift linkage is set properly and comfortable for you. I had trouble with the shifting being inconsistent the first 1000 miles after that it seemed like the motor/trans broke in and I also switched to Amsoil 10w40 synthetic. Between the break in and switching to synthetic oil that seemed to help a ton. Let me know how this goes and we can go from there.

When you let the clutch lever out there should be "play" in the lever so the clucth fully engages/disengages
