2014 standard, clutch fluid hasn't been flushed as I recall(second owner, 2600 miles now reaching 11800) I do ride a tad bit aggressively. I was testing the limits of the bike and in the first months of riding her I had made some missed shifts from 1st to 2nd in high rpms where it would clunk and sometimes force into. Nowadays, It doesn't happen at all anymore, I'm not consciously trying to redline shift 1st into second and completely doesn't happen anymore. I have noticed that once I get into higher rpms exclusively in 1st it revs quicker than the speed it's picking up. Every other gear is fine only noticed it in first.

1000 rpm = 10mph
2000 rpm = 20mph
etc. If you can't jot it down while riding, have sb take pictures of the instrument cluster from the back seat with a cell phone.
Now look, does the ratio change at high rpm ? say, do you read 6000 rpm but only 45 mph instead of the expected 60 mph.
Again my numbers are invented. You have to find the ratio for the 1st gear of your CB1100.
Will do!
