Drain oil and flush first with diesel or kerosene, then run some cheap oil through it. put some clean and fresh oil in and run for a while, if this is milky then it is going to be...

Hi Ceaser welcome aboard. Yes it is a bit of a job at times to get the VDST software to connect. Here is a thread where we worked through some connection problems. http://www.gasgasrider.org/forum/showthread.php?t=4175 Have a read and if there you are still having problems let us know...

If you have had the throttle position sensor (TPS) of it will pay to use VDST software or similar to do a TPS reset. As long as the injector is rated the same as the original the fueling should not change or need adjustment.

With the Technoresarch VDSTS you can get two versions of software. A pro version or a standard version. The standard version just requires the correct cable and adaptor box to work. The pro version needs a dongle or hardware key to work. The software maybe looking for that. If you think the...

The later models with the kokusan's like yours use a JAE MX23A connector. To repair your ignition properly it would pay to get some contacts for the connetor and rejoin the wire with a new contact. The contacts are available through Digikey part # 670-1682-1-ND or let me know where you are and...
