What about the reed valve? Have you checked it? JR Stripped the carb off again to do the reed valve, it looks like new with all three flaps aligned correctly and no dirt present. I may have to splash out on a new piston/ring set in the near future as I'm running out of ideas and compression as you know is key for 2 strokers.. The workshop manual arrived , it is extremely detailed showing various ways of checking the electrical components, fault finding etc so I'll start checking the spark circuit as I'm not convinced the bike is firing at every revolution (may be a red herring as it is firing on starter fluid, just sounds funny) MrJennzzz, thanks for your input, however as I'm in the UK, buying parts from you costs will be prohivitive. Go well. |

Hi Luke, ok so no petcock then (whatever that is  Starting fluid - already atomised as a spray direct into the induction, mixed with diethyl ether - so should start anything really. Worn piston, yes I will replace it as they are cheap. Ideally first, I would like to get the old girl running/firing properly before forking out money on pistons - but as she wont start - just firing (seemingly erratically) It may be the way these things run though. I'm going through checking the cheaper electrical options first. Appreciate you input, keep it coming thanks. |

I'm thinking similar to you, however, charged the battery up and tried restarting after cleaning the carb and it's still not starting. Then did the quickstart thing again, as before it started firing, but not actually running - so having never tried this method on 2 stroke before, I am not convinced that she is firing at each revolution. Anyway, I've recieved a genuine workshop manual for it so will dig deeper this weekend (after the Rugby and Forumla 1of course |

Just managed to source a genuine workshop manual so thats o its way to me now.  the scoot has a seperate oil tank so it's done internally. Not too sure about the petcock, its got one of those vacuum taps (same thing?) which works when I suck on the induction side - carb bowl tap drain screw loose, suck on the vacuum hose and fuel runs out the bowl - all seems ok. Watched the video supplied and will follow the same process with wires etc thanks. |

LOL and BTW do you have any type of manual on this scooter? I helped a guy from England fix a problem with his in another thread in this section and his only manual was in Dutch! If you do please PM me. JR Hi JR, yes I saw your posts with him. The only manuals I have come across has been Haynes manuals on UK ebay at @gbp18.00- they unfortunately cover a whole pile of different manufacturers, so I don't believe they would be as 'in depth' as we would like. Saying that, I'll probably end up purchasing one soon- better that than nothing. |

Thanks for the link JR, I'll have a look later after work , just finding my way around your forum, it all seems young,new and strange compared to the wee stained/smelling BMW biking forum I'm familiar with |

Hi, just arrived here.
Bought the wife the above mopey to see how she gets on with 2 wheels, before committing to serious money only to find she is not keen on 2 wheels.
Sky is a 2 stroker for those not familiar with this little beauty.
I have good compression and bright spark.
Tanks have correct fuel and oil respectively.
Battery is fully charged.
Not the done thing I know, but I had to prove she does fire - I sprayed quickstart into the carb whilst spinning the motor, eventally the quickstart did it's thing the the old girl started firing, not running obviously. I stopped after she had fired 5 or 6 times, mindful of the potential for running bearings dry etc..
Looks like fuel is not getting through to the cylinder.
So, next step is removal and fettling of the carb.
I know absolutely nothing about them and just need a little encouragement to help get me going.
What product is best for cleaning it
Any advise on setting it up so that once clean and reassembled I can adjust idle/fuel mix to a factory type setting?
In anticipation .......Flatty

Thanks for the warm welcome folks. Cruiser, Beemers, yes I've had them since @1982, either love them or hate them, a lot of my friends are usually surprised how well they handle in the twisties. Had numerous fast 4 pots but now prefer pottering about.  Alleyoop, thats the one, Nice little scoot to work on so far. (read basic as I'm simple) Looking more like I need a new carb or something associated with fuelling......sorry off topic here. This is the welcoming place. |

Just signing in to say hello, Been a biker for 30 odd years, currently own a BMW 1150 GS, my missus now wants to 'feel' the love of biking, so took the plunge and bought her a little Honda Sky 50cc moped (non runner atm) so thats why I'm here really, don't know too much about them and look forward to asking plenty of silly questions in the process of getting it running again.
Thanks. Flatty.
