tyrslider,
I thank you !
I happed by a small shop and dropped off the recently cut goose neck of the original muffler to see if they had that size, (they weren't in when I got there), so upon calling them they didn't have anything that small.
Being without ample transportation at this time, I was without a way to size this, if I were to get to the Kawasaki shop, so is the reason I was asking.
I may as well be, off the beaten track, in the back country of New Mexico, with a bike in need of repairs, where the mail man is the event of the day !
But, thanks again, I'll look into it.
