hi,
i recently purchased a 100cc speed fight 2 and it worked fine until a few days ago. within 2 week i rode it about 5 times and started if up for 5 mins every other day.

i was riding to a mates stayed inside for half an hour and after coming out it just wouldnt start.

i charged the battery up from a car for 10-15mins because the battery was completly dead after trying to start it for a while. the battery is now charged and it still wont start.

Im very new to the bike scene and any useful imformation would help.

here is as much imformation i know about it
Its a speed fight 2 100cc 53 reg
it turning over but not starting.
the kick start is next to useless!
the imobiliser light switches of when you stick the key in.
Its full with petrol and 2 stroke oil. i put the petrol in the other day so as far as i know its not due to old petrol.
the battery has been charged for at least 10 mins so the electrics are working ie indicators horn lights ect.

Many thanks for your time.
Danny

Hi I was riding along the other day and my moped cut out at 60 mph. When I get to 55 nearly )0 and let go of the revs it sounds like something from the variator side is causing this to happen

I have excactly the same problem but mines leaking lots of oil out of the exhaust, ive just bought a new piston kit with everything i need such as rings, piston, gasket, gudgeon pin and circlips.. Has anyone else come across this problem with the oil coming out there exhaust and has anyone ever come across when the bike starts once it wont start again as that is what mine is doing :/ could this be a faulty CDI unit or an immobiliser problem?? Couldn't i just get an immobiliser bypass unit to bypass the immobiliser and get a de-restricted CDI unit????? Help appreciated guys as im so confused it is unreal, i had the bike for a year and only the last 4-5 months its started to do this :/

Having a problem starting my 03 peugeot speedfight 100, if I have a freshly charged battery + a cold start and little messing about and ill be able to get the bike running, but when I turn the engine off after a ride and try to start it with the engine warm - No Chance will only start when cold, also when I get the bike to idle its idling at 5000RPM which isn't good considering its ment to be idling at 1600RPM could this be a faulty automatic choke??

Check your fuel /oil mixture this is very crucial as I had the exact problem with mine upon doing some great research and spending a great deal of money on unnecessary solutions I came upon on simple answer ....... On the times when it does start but just keeps "bogging out" the best way to describe when it sputters and looses power but still runs you need to screw in both or one screw dependant on the model on the side of the carburettor until it cuts out then your half way there all you need to do is turn that/both of the screws back one and a quarter or one and a half turns there you have it the correct mixture ...... Start your engine again and you'll find the performance is not what your once used to this is why there was as I said earlier the quarter and the half turn just have a play about until your happy I hope this helps guys and galls the only other problems that it could be are as follows
: blocked jets - soak in water overnight NO SOAP
: faulty / broken restrictor regulator ( converts ac to dc ) about £30 from bike breakers
: new piston and cap needed - about £60 from the bike breakers
: new piston and cap needed

right firstly you need to see if it has a spark from the plug as these speedfights suffer from immobiliser problems alot.take the ht cap off the spark plug right hand side of the back of the engine in front of the rear wheel its in the middle of the black plastic cover on top of the engine you can also acces it from under the seat there is a small black plastic panel you lift up.then undo the plug with a 21mm spark plug socket pop the ht cap back onto the top of the plug and rest the side of the plug against a metal part of the engine then press your starter button and see if the plug sparks.....let me know what you find ok.
