Hi everyone

So I've had a few problems with my ybr but the latest is this, if anyone can give me any help. In the morning it's starts fine first time but then if I stop half way through my 30 mile journey for say fuel then I can't start the bike again. If I leave the bike for a while to cool down then it starts. My only thoughts are that it has something to do with the engine heat. I've checked the oil and it all seems fine, does anyone have any other things I can check?

Thanks

Neil
