Bought this Chinese quad used not running. Got it running, 8 year old has over 10 hours on this quad in 3 weeks.

It was listed as a 90cc, but I can't find any info. Also has no air filter and previous owner had no clue what one was....

Trying to identify what quad I have an I have get parts, air filter and new carb to start.

One photo shows what looks to be VIN... But it's 1 digit short.

 

if that is in the engine its probably the engine serial number.. The vin should be stamped on the front down tube or have a sticker... Carbs and such are mostly the same just look for a 90cc carb that looks the same.. Or you can measure the inside of the intake of the carb intake and match it that way. Until you get a filter on it id stop the little one from riding it.. wont take much dirt and crap in that carb to mess the engine up

 

YG152FMH are usually 110cc clones of Honda Cub engines, though Chinese stamping can lie, and the 52 is the bore diameter, so a short stroke 90 could have a 52mm bore. 90cc engines usually have a 47mm bore. Why change the carb if it is running? Just get an air filter and stick it on.
