I purchased a four seater off

I purchased a four seater off roading go-kart at the end of March and had friendly service over the phone, was also given a coupon code for a little extra off. Price wise, including shipping, this was the best price I found. The package was delivered in about a week in pretty decent shape. Make sure you read the all the disclaimers on the site because you'll have your work cut out for you. Focus on the warranty and damaged parts which I'll get to in a minute. First off there were no assembly instructions or parts manual. Included was a 30 page operation manual which had a totally different 2 seater kart and basically told you how to start it and put it in gear, that was it. I contacted GoKart USA and Dong Fang CO and was told I was out of luck, not all karts have instructions and was advised to take it to a shop for assembly. The reasons I chose to buy online and put together myself was to save $$ otherwise I would have bought it in a store fully assembled with no headaches. Had I known there was no assembly instructions, I would not have purchased it. I did countless searches and downloaded assembly instructions to other karts from other sites, however there was nothing close to the kart I purchased. My father and I were able to assemble it in just over a weekend by figuring it out ourselves as we both do light work on vehciles. While the engine and cables were already installed, you have to pretty much put together the rest of it. The frame, being so heavy, made certain things difficult. The turn signal/bright light gauge was broken upon arrival and the two front fenders snapped at the base the on the 2nd ride. I attempted to get those items replaced under warranty and was told no. To make the request for a warranty replacement cost $15 only for them to tell me the gauge did not appear broken and would not be replaced even though the pics I sent focused on the broken brittle plastic piece where the gauge came apart. I was then told fenders often break and was advised to remove the fenders prior to riding. I have requested my $15 back from the warranty request which was denied and are still waiting on that. So the service was good at first than pretty useless once delivered. Verify that a assembly guide exists for you kart ahead of time and don't count on the warranty for anything. And if you plan on registering it, keep in mind that since no taxes were paid, you may have to pay taxes on the purchase when register as is the case in AZ which came out to just under $300. Dan in AZ ***Response*** Go Kart USA, thank you for your response. The only reasons I did this review was in response to the email asking for a review. Since we're here and due to your awesome "Oh Dan, classic" response, I'd like to clarify a few things. You asked if I performed assembly myself, yes I did as that was mentioned above. To get specific my father, who was a qualified mechanic and certified for over 20 years, assisted, technically assembly was preformed by a qualified mechanic as a mechanic is a person who repairs and maintains machinery. Now I'll admit that I did not notice the broken gauge or report it within 48 hours of delivery as required. This was due to postponing assembly as I had not received an assembly/parts manual. By the way I had asked many questions to the rep I spoke to about assembly specific and was told there would be a manual, if for whatever reason it wasn't included, call back and they'd re-send it. When I called back I was told to complete a ticket and they would contact the manufacturer and have one sent to me. I later received an email stating there was no manual. The point I'm trying to make is that I was told by phone an assembly manual would be included and the description even reads, all manuals can be downloaded. The warranty reads, any damaged or missing delivery items will be replaced. I know it's a cheap product and you get what you pay for so a broken gauge and fenders are not the end of the world. It has actually been a fun little buggy and we've enjoyed it so far. I was just trying to make buyers beware, as I stated above, with making sure they focus on the disclaimers to avoid headaches.

Oh Dan, Mechanic Required!!! I know this is clearly stated on our site, and on our purchase agreement. Skip the dealer and get the low low price. If you can assemble it yourself, thats great. But if not, you will need a mechanic. Take it in to one of our service centers for assembly.
