Many thanks for the replies been busy weekend so will start looking into the suggestions

Hi all, new here looking for advice please My son recently bought this bike as running (it was running day of purchase) but since then has failed to start on the electric start, we can start it by running down the road and bump starting it then it would start the next day but the day after it was back to needing bump start. We changed battery as it seemed a bit weak but again would start for a day but next day not unless bump started, we changed starter motor as there seemed a lot of play in original one and changed the starter solenoid... needed bump start and ran rough but restarted fine after... tried a few times and ran fine, but 12 hours later and the thing wont start sound like engine is trying to start (did take video on mobile phone but can't seem to upload it here???) any ideas as he has managed about 20 miles riding in the three weeks we have had it and getting near end of warranty Do not have tools or equipment/knowledge to deep dive testing things I assume spark at plug is ok as bump starts as is fuel supply for same reason there in ends my knowledge... its his first bike and he is now rapidly losing interest and faith in it
