SPEEDFIGHT 3 50CC E10 PETROL BREAKDOWN CARB & GASKETS FIX MOPED SCOOTER

[@FrietjeM]

Hi I have a question: my speedfight 3 ac 2t, has problem with kickstart and electricstart: the fuel pressure seems off (the fuel go’s up and down). It doesn’t keep the pressure so that the fuel reaches the vacuum pump. I am not sure wether I have placed my vacuum pump in a right spot. It is near the 12v buddyseat cables.

i hvae a problem with mine it will run on rich for some time and shut down if i change it a litlle bit more lean doesnt even start i would like some help

[@CZ350tuner]

I've found that E5 causes the washing away of engine crankcase sealant around the crank bay area on three 125cc 2 stroke single engines that I've had to re-seal with ethanol resistant Blue Hylomar. Around the crank bay area all the factory RTF or previous rebuild silicone was gone, which was why the engines had started burning their gearbox oil. This is because ethanol dissolves silicone & RTF (original black rubbery factory crankcase sealant).

[@marksavage]

and thats e5 so what do you think e10 will do lol

[@fergie3184]

i use e10 in my 2003 Peugeot vivacity, it’s very similar to the speed fights in terms of engine, I’ve had no issues since I replaced the carb and change my head to 65cc airsal sports kit, but my original 50cc piston rings broke soon after buying it ( only had 8000 miles on it or so) thinking about e10 my have caused that, I also premix all my fuel going into the bike, anyone have any thoughts on this?

[@jack2010howe]

Hi mark I took my speedfight 3 apart to re spray the body parts on it and I found a pipe which wasn’t connected to anything looks like it’s for air flow as it’s not from the radiator or anything the pipe was hanging down underneath my plastics and was clipped up to just under my seat do you know if it’s for anything important I’m thinking it’s not because the ped should have broken already if it was important it’s just a black pipe with a black box connected to it and on the end it looks like a showerhead end let me know what u think it is as I can’t see it on the owners manual or anything

[@marksavage]

It's the grv gas recycling valve Don't worry about it as it would have gone to your exhaust Take it out and chuck it bud

Hi Mark could really do with your help. My sons scooter just stopped working I have changed the stator, the regulator/rectifier, new ecu, new ignition coil, new spark plug and the side stand switch but still no spark. There is power in the ignition coil but none when spark plug is inserted. Any ideas welcome xxx

[@paulbudford]

If you know the coil has power, and is goo. Replace the HT lead and plug cap. Then see if you get spark from the coil to the plug.

if you have done all that bud id be looking at your cdi again , power going in and back out as you can buy a duff one get a volt meter and start from battery and all the way along , dont forget wd40 all wires and make sure no breaks

@@marksavage I changed the plug, it did look a bit ugly but not white just a usual rust brown. Seems to have gotten used to super unleaded. I don't know if that's the malossi Digitrontic at play. I've asked everyone but do you know if you should remove the secondary air system box as it's not connected to the power pipe? Some people say leave it on and others block the hole with a car wheel bolt. The Digitrontic handles the sis valve but does that box serve any purpose now the exhaust is gone? I would really like a definitive answer as it doesn't seem to serve any purpose.
