2005 Honda Foreman TRX500 FM Compression Question

Hey guys, I just ran a compression test on my 2005 Honda foreman TRX500 FM I just picked up, its reading 125 PSI, but in the repair manual it says it should be reading 64 PSI due to its camshaft having a ‘decompression device installed’. So I`am either double my compression, or I don’t have this decompression device, or its not working, any thoughts ? Is it even possible to be double your compression ? The bike runs good, but is running rich with carbon build up on plug and tail pipe, have to pull the carb soon for a good cleaning and check choke plunger
