I know it wasn't the same number as what I put in which was BPR6ES. You may be right.. I don't know what the platinum number is. They were not all the same plug either but all of them were in bad shape. If I hadn't of already tossed them I'd be able to tell you what they were.
I got the fever with this thing and can't wait to get digging in.
Things were different with my ZX12. I had expensive upgrades forced upon me when it dropped a valve 142 Kms past my warranty and Kawi told me to get stuffed. Even though I built a monster machine out of it I never quite got over how poorly they treated me. Worst part about it was I had it into the stealership 2 weeks prior at 19,500 for its 20k valve adjustment. Then it drops a valve at 20,142K? No causation? Riiiight....
It was going to cost 6500+tax to repair it back to spec with factory kawi parts. Destroyed the head, cylinder, piston and connecting rod. For a few thousand more I ended up with a 1290cc Carpenter race engine. CNC machined head, NOS pistons, Muzzy billet basket, lock up clutch, progressive NOS controller, bottle etc. It makes 220 at the rear wheel on motor alone and 320 on the bottle.
It's an arm stretcher for sure.... but my heart just isn't in it any more. As junky as this is right now I'd rather ride it. Weird? Maybe. There is one thing this has over the 12 and that is the SOUND. Even with a leaky exhaust I like the sound better.
