No Need to grind anything.
The factory indexing tab on the speedometer gear box fits very Nicely/Perfectly Behind the fork leg tab. The first time I saw this alignment was on a travelers/tourist bike, which we were discussing excessive vibration, doo-hickey adjustment or replacement, poor fuel mileage & overly tight drive chain tension.
The tourist suggested that his local shop in Colorado had apparently assembled it that way by accident when replacing tires, like his overly Tight drive chain. I readjusted his drive chain to the looser side (like I've recommended many times to many people). Adjusted his engine balancer DooHickey. I also aired up his tires, to my many times suggested PSI's (for his load).
But I decided right then and there that this 9:00 position would be kinder to the Gen 2 speedometer cables. After my second test ride & his short road test also, he headed North.
About a week later, this same tourist stopped back by to say thank you, for a smoother ride, crisper handling & nearly 10 extra mpg. The westward detour back to my shop added about 100 extra miles to his day, but he was that appreciative of the great and simple improvements.
And I had learned a new trick by accident!
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 84,000+ miles & counting

Reason: Pardon my error, it was Norton850 that mentioned possible grinding.
