Thundercat v Fzs600 clutch perch

[joebloggs]

Decided to go with clipons after not liking to streetfighter look of flat bars. Had a pair of Thundercat bars delivered today which obviously fit but the FZS clutch perch fowls the fork mount not allowing me to slide the clutch all the way along the bar. Wouldn't be a problem but it doesn't leave me with much bar to fit my grips etc (10cm from switch to end of bar)
Does anyone know if the two perches are different?

Sussed it out, looks like I've purchased some cut down bars, probably a track bike.
Have some 22mm alloy tube so not the end of the world

Or do what I did for my Thundercat.
I got a pair of standard screw in bar ends and machined them down to 22mm dia. Got an extra 25-30mm each end bar width with that mod.
