Supermooser Posted August 5, 2011 Share Posted August 5, 2011 My bike starts and runs fine for about half an hour - then it cuts out. If i kick/push start the bike at this point it will not start. When I checked the spark plug at this point there is no spark. If i leave it for a day/week and try again - I can see the plug is sparking again, having altered nothing! However, when I replace the tank etc and run it for about half an hour it does exactly the same thing again! I think it may be a coil problem but the coil looks fine/not loose/cables etc. I've replaced so many unnecessary parts on my bike trying to solve problems incorrectly - Is there any way I can test my coil before getting a new one ?
