Thundercat clipons begining to p me off

I can measure mine tonight, not sure exactly what your problem is- standard grips fit just, the standard bar ends for T'cat are massive btw!

Yeah and thats where the problem was. I couldn't see where they had been cut until I saw a standard bar end, then it was obvious. The previous owner had cut off the part where the shoulder on the bar end fitted leaving just the thread showing, thats what confused me. Thought it must be the end of the bar, and it was, but not as Yamaha designed it  :o
