Cant scrap the lean angle limiter (screw)

[agricola]

Hello guys.
I've something that is puzzling me.
I bought a used FZS 600 (98-99) that had no lean angle limit warning screw (under the footpeg). I bought ones from Yamaha, which I suppose are the original. I have never managed to scrap it on the tarmac. My rear wheel is totally used on the right side. There is not a 1mm "chicken strips" on the right side of it, so I would suppose I should have already scrap it on the tarmac. But that never happened. I fear I may reach, or go over the limit of grip of the tyre and may loose the rear wheel and crash, as I have no indication (by scrapping the limiter) that I ve reach the limit of the wheel grip.
Do you have an explanation for this?
Thanks
Mike

Hero Blobs. Screwed mine out years ago, fed up with scraping them. (FZ6 S2 fazer)
