My Sunl go cart is terrible. Every time i fix it, it breaks again. when I got it, the first problem i had was the shocks that came with it. the seals that held the pressure broke and the hydroc floid leaked everywhere. I had to go all the way to Texas and buy new parts for it and fix it myself. the second problem that i had was the gas pump going out and the gas tank completely leaking out. Third problem was my gear box going out. I was shifting and the gears shreaded the locked up. To fix that you had to completely take apart the rear end. the shifter snaped and I could never fix that part. and the entire time the oil leaked and I could never keep the coolant filled. The front right strut sheered off while I was driving, the wheel, and the entire break assembly came off. So the thing is a peice of crap and ended up spending tons of money. the entire time I drove it, it was very unreliable and annoying. if looking to buy any SunL run the other way, FAST!
The complaint has been investigated and resolved to the customer’s satisfaction.
I bought a 2007 Sunl ATV 150cc from a friend that his boy seized the motor, The oil cap for the strainer came loose and leaked all the oil out. Bought a piston/gasket kit on E-Bay under $30 and honed the cylinder . Also replaced the cracked fuel lines with 20 year old honda fuel line I had lying around. My son has been riding it for 3 years with no troubles. these GY6 clones are fairly good, you just need to keep an eye on the oil and change it often because they don't hold much oil ( about 3/4 of a quart). Not bad for a $130 ATV
