i have a 150 cc quad. No to sure what the brand it is . Can anyone help me out. No vin number or markings

 

Not much to distinguish it from a dozen other makes from about 15 years ago. As it has a sump filler plug, I guess the engine must be a GY6 four stroke, though it looks very similar to the Minarelli two stroke. Not too many ATV makes used the GY6 engine, so that narrows the field a bit, otherwise only that perforated trim panel, above the exhaust, is different from other GY6 engined 150s.
