I know you know....many VFR owners boast of never checking their
valves, even into high mileage.
I checked mine at 20K, 11 of 16 were off, i think 10 tight, 1 loose.
All corrected, bike sighed a big sigh of relief. I was rewarded with a super stable idle, instant push button start, engine at ease. Effortless off idle acceleration.
I prefer to follow factory directions, and leave stuff alone. Airbox, flapper valve left intact.
Relating this to 250.....friendly advise.... don't blow off valve checks. In your best interests...adhere to book maintenance schedule.
