A quick one I hope people can help with. Was out riding this evening and after an hour or so the bike began to hesiate whilst riding so I changed to reserve. For 1km or so it wouldn't go over 90kmh and was really 'doughy'. It finally stopped. I stopped the bike and manged to get it started again and rode to a nearby fuel station. I managed to get 8 litres in te bike so I'm thinking that there was enough fuel in teh bike.

Any ideas what would have caused teh bike to hesitate and finally stop.

As an aside when out on Sunday had a similar situation but kit seemed ot happen after a reasonablyt long climb.

Cheers

If it only happens when you've been riding a while and the engine is hot yet starts up fine later...possibly vapour lock?
