I have a Metal Motorsports (Chinese I am sure) go cart with an engine number: JP57QMG. I have a suspicion the R/R is bad, it isn't charging. I would like to make sure I get the right one, but the internet is showing nothing for this engine!

 

all chinese parts are the same .ul find cheap parts on ebay

 

alix, just think a little about what you wrote.
Quality parts come from most factories that are in joint ventures with your OEM brands. When the tolerance of their equipment moves below what is acceptable they sell it. The second factory uses the equipment for a set period then they move it on to the 3rd factory.
Now lets look at the internet..... there is a race to the cheapest price on the EBay/Amazon....markets. Which factory will give the best price?
All that glitters is not gold.
You might get lucky but you usually get what you pay for.
Buyer Beware
