The top half of the left hand switch gear on my Kawasaki KZ1000 j1 broke. It’s the switch with the indicators lights and horn. Looking for a replacement, they were all around the £60.00 mark. I sourced the switch for a GPZ 750, swapped the internals round, and everything fitted perfectly. Exactly the same as the original and it was only £12.00. Result.
