Hi every body. my names Nathan im from leeds I'm new to this club i have been recovering from a accident on my yamaha dt 125 re and as a result my bike has bin stood for ten month. I changed engine oil, 2stroke oil, water and coolant. I checked spark plug and it was sparking perfectly. It was riding perfect for about a hour then cut out on me It wouldn't start so I bumped it but it kept cutting out when I took revs off. I bumped it again and rode it for about ten min hoping it was 2 do with the battery as it kept running flat when trying to start it. It cut out on me whilst riding after ten min and wouldn't bump.when I did have it started it wouldn't tick over. I have put a new battery on and fresh petrol. It started up and ticked over for about 15 min before cutting out it started again but cut wot straight away. I have checked spark plug again and the spark is very small the bike won't star or bump now. I have tried changing the ht lead and coil which made no difference I also changed Cdi unit and still had no joy. I first thought it was a fuel problem then a electronic problem and now I have run out of ideas somebody please help me I have bin trying to work it wot for 2 days now does any body have any ideas????????
