I have a TT225 that will start and run perfectly for 1km then splutter and die.I leave it a minute and it will do exactly the same ditance again before it dies again.It seems to get hot then run rough as guts.Ive checked all the electrics, tried a new carb.Noone I know knows how to fix it including a motorbike mechanics.Not really worth taking in to the shop to get fixed anyway.I have had the engine in pieces 3 times putting new gears in the gearbox.I also don't have a second gear(just acts like another neutral) if anyone knows what I may have done wrong their it would be appreciated to.

.Could it be a filter inside the fuel tank being blocked

2 or 4 stroke. A two strokes sump has to be absolutely airtight particularly the crankshaft seals. If its a four stroke any of the other suggestions could be right.

Either some thing's wrong with the Fuel delivery or Ignition Coil or CDI or Stator.Those are the normal things to look into in a run and conk out situation.A mechanic who can't fix those by cleaning or swapping in known good parts or diagnose them as possible causes is a useless chap.,,and a 225 is a 4 stroke.

The 1km then die sounds like a fuel supply issue to me, float bowl not filling quick enough, I'd start looking at the fuel tap, fuel filters, and fuel line.If it is a tap with a vacuum cutoff (fuel flows only when vacuum applied), replace the vacuum line after checking that fuel flows with a manual draw (suck on it - the vacuum line not the fuel one!).
