Not needing adjustment ('til some pretty high mileages) is normal- My S10 was still within spec at 26K and 52K and my BMW F800S with similar valve gear was within spec at 24K, 48K, and 72K. Long Haul Paul didn't get his checked until after 100K!
Speak to Steve at ZZR Works in Worthing. 07808 861823. It’s a bit of a trek for me but he’s the only person I trust with my bikes. He also sends a photo commentary of what he finds etc.
