I bought a used Youth ATV and I cannot find any info on it on the internet. Looks like a Yamaha. Stickers say "Vmaxx" spelled with two x's. Mudflaps say "YZ". Engine says "Linhai Yamaha". I have searched the VIN but no info from it. VIN sticker says mfg by Yonghe Motorcycle in late 2003. My guess is its a 90cc or so? Anyone ever see this thing before?
