there is computer model to calc, this using compression ratio and cylinder volume
but
here is generic list.
my lawn mower is 100psi;. (and mopeds and outboard tiny motors and scooters tiny not 250cc hog scooters)
my old car is 150psi
my newer car with high 10:1 CR , is 200psi
a 49cc engine 7.2 CR is like 80psi.
low and expected. at that CR, 100 max
to get the reading correctly
good guage
fast cranked (kicked or starter turned)
let the meter peak and peak is spec. read peak PSI
and the CR is what matters.

Please advise going price on a 2nd hand Kymco 500 scooter
Arriving at a fair price for any secondhand vehicle is very difficult and many variables should be considered though in the final analysis anything is only worth what the market will pay - if the seller asks too much the buyer will walk away.
There are many publications providing guide prices for all manner of vehicles - but these are only a guide and some models tend to command higher prices because of a good reputation while other models with a reputation for trouble or high running costs can fall far below.
No vehicle should be bought without a thorough inspection and price adjustments made for faults found and any pending work, taking due consideration of fair wear and tear.
A service history is important but will affect the price only if it can be fully verified by the presence of official invoices and a vehicle should only reach the guide price if the literature pack, the full complement of keys, tools, accessories, etc. is present. The replacement cost of some of the modern keys can be eye-watering so it is important to think ahead.
The presence of local dealer expertise and a spares service is worth a little extra and the absence of a local dealer drives the price down a little.
I hope this helps...
