Hello to everyone out there, I am new to the forum having just taken delivery of my brand new GTX is 255 LTD and very proud of it too! I put it the water for the first time a couple of days ago and within minutes I noticed an amber service light and the message 'Maintenance Required' on the LCD. The stored Fault Code is 1658. To be honest I dont know if the light was already showing when I started it and in my excitement, didnt note whether it beeped twice or not. However, now I notice that I only get one long beep when I connect the DESS Key and the light stays lit even while I continue riding. Everything else seems to work fine and the bike pulls well into the upper rev range. When I kill the engine though, it sometimes will not turn over at all for maybe 10 mins even though everything cycles through on the instrument panel. When it does eventually start, it runs perfectly. Glad for any advice, many thanks. BTW, great forum!
