My scooter is at 2K miles, runs fine doesn't stall, top speed around 55mph gets an average of 60mpg with some aggressive riding. I hear no tapping.
Valves were never adjusted. Is there a mileage where you should adjust them no matter what? Or do you have to feel and hear symptoms before you bother? Advice is appreciated. Thanks!
By the way, how much should I expect the cost to be? Valve adjustment is a bigger job than what I am comfortable doing by myself.

I would say adjust valves every 2000 to 3000 km.. But if running fine and not stalling out or backfiring, well I would wait until you have problems. Why people adjust valves is because it isn't running right. Like another reason to adjust valves, is it might be getting to hot. This would indicate that the valves are to tight and need adjusting if getting to hot.

Depending on the scooter, it runs about 65 bucks in my neck of the woods. The valves tighten over time. The scooter will become a little harder to start, a little cold blooded and have the annoying habit of dying at intersections. If it starts doing any of these things, get it done pronto. They can and will burn exhaust valves, if this condition is ignored.
Service intrival has been about 2500 miles for my scooter, but it does vary from bike to bike....

Thanks all. I guess I'll leave it alone until I notice something wrong...
$65 to get it done at the shop seems reasonable.

it's about a 20-40 min job depending on how many body parts are in the way and how many tries you need to get it right (took me 2 tries) but it is not hard and I would not pay to get it done. Having a 2nd pair of hands also helps a lot.

very much depends on the bike. Mines takes about two or three hours. I have a Retro style, Unplug the lighted trunk, off comes the rack, the rear plastics, seat pan, the floor board, under floor board skirts and then and only then can I get my fists of ham and my fingers of butter in to adjust them. Do I trust the shop to do mine? Oh H E double hockey sticks no..... And while you are at it.... change the oil, gearbox lube and adjust the rear brake.
And chant "I love my bike, I love my bike, I Love my bike" (works better then calling it a bunch of names)

On the retro you just take out the seat bucket you don't have to take the back end off the bike. It is a little tight getting to the valve cover bolts but if I can do it with my XXL hands then anybody can. Once you get the valve cover off then it is fairly easy with just a little bit of fuss on the exhaust valve. Until the valves seat to the heads you can be doing the adjjustments every 1,000 miles. You won't have noise if the gaps are closing up only longer valve durations and eventually hard starting and possibly a burnt exhaust valve when the gap gets small enough that the valve no longer stays closed long enough to get cooled by good contact with the valve seat.
