Hi Guys, I bought this bike 3 weeks ago with 33.000 miles on the clock. It got a new battery when i bought it and since then i drove like 300 miles with it. Today i drove it and after 5 mins of driving it there was no engine power, it went off. Now when i try to start it, the startermotor tries but it only gives a sound of working for half a second, and then it stops. There is power on the battery, horn, lights and all electrics function. ' My dad says its a problem with the dynamo but i have litteraly no clue. Anyone familiar with this?
