Hi
i recently purchased a Yamaha SR125 it was ok when i went to see it, but as it was late by the time i got home i just took it out the car and put it in the garden. Anyway it takes a long time to get the engine started messing with the choke (which doesnt stay out, it has to be held out) and once its warmed up (which takes about 10 mins of holding the choke out) during the first week or so of using it after getting it started it always cuts out at junctions and traffic lights unless i keep revs on, and then the other day i took it out and was going along a 40 mph road and it tried cutting out but the more i pulled on the throttle to keep gas on the more the engine seemed to want to cut out, after this it seemed to start up fine but when i got down the road it did it again and this continued on my journey home and so i dare not use it. What could be the problem and what is the solution,
cheers in advance for any help and or advice
