Hello, my name is Asif and I build a go-kart with a 600cc Yamaha engine. I have the go-kart chassis and engine, but I am about how to extend the rear of the kart confused. Because the engine is too big and heavy. I have everything needed to operate it, but you know that someone be able to install, the engine will go-kart? The work must be very simple. I am very desperate to know where I can perform the installation. Only need to drill and screw clamps. How much does it cost for someone to do the job? I have all the management system electric motor.
