I suspect you have a couple of bolts and two washers left over, ie parts list numbers 7 and 17. Where do they fit?. Have you noticed how poor the coating is on the metal parts, keep an eye on rust which will soon appear.
The poor quality finish is equal to the poor quality finish on the grab rail. Has anybody else complained to Suzuki about the grab rail?
I have heard that some people have had a replacement better quality finished rail.
