as geh3333 said but mine was too short, had to flip the the holder on the carb upside down and bend it a good bit to give me the slightest slack, when that one crapped out i went to a scooter store, the guy sold me a roughly "standard size" and was even shorter. so it was useless. i'm pretty sure his scoots are the mostly typical chinese, but i did notice they had a different style carb setup, so as these things evolve people will be stocking many versions "or just the newer like him" being a bit crafty i went to lowes and bought good braided cable (something like 39 cents a foot) and made my own reusing the the housing. kits are available for doing the ends but i made mine. the little one for the throttle handle was very difficult with what i had so J_B weld to the rescue. i lubed it well and its been working very smooth for months, but if it goes again, i will do this again too unless the housing goes. like new, and only a few bucks instead 20+ |

sounds to me like your starter clutch is slipping, don't know about a low batt. causing it (but not saying it couldn't) as i have had many an issue with bad batts/bad r/r's not charging etc. and never did my clutch slip, it just turned too slow or not at all. it uses sprung rollers that wedge against the the clutch bell (for starting but let the bell slip past while running and the starter is not) and if they get gummed up they won't wedge tight enough to turn it and the starter just spins (the whirring sound). it is a royal pain on these gy6's to get to them but they are cleanable and fixable.
I know i didn't describe that very well, but hopefully someone else will take over for me haha

The fuel has a longer way to go to get to the intake valve,,its going downhill so wonder if it acts like a ram air,,kinda good in a way cause the mix stays cooler,,and cooler means more power.I would like to see a pic of it mounted in the scoot. cooler is better for sure but ram air is actually having your intake facing forward and into the wind having air get "pushed/rammed" into it at speed and does nothing from the get go. also, ram air does not work without a mass air flow sensor and EFI so that it can adjust the fuel for the air at any given time. on a carb engine it just makes you run super lean and not good for the engine. i suppose you could manage to set it up to run extra rich at lower speeds but.... |

are videos posted the same way as pics using the pic button? and if so by chance does photobucket take vids too or do i need to find another host to upload to first. i have a flickr account but i really only want my animal stuff on that account. thanks

Well the tit is rounded off on the forward spinning side,,its squared off/FLAT on the back side,,so when the motor is running forward the rounded side of the tit slips past/OVER the square extruding piece on cam,,when going backwards it will lock right into place,,just like a ratchet...or fishing reel like mentioned...Im seeing it now,,thanks guys!! the opposite. in forward the part on the cam stands still due to the part on the rocker assembly and the cam spins freely. in reverse it spins WITH the cam but the part on the rockers is springloaded in the same direction and just lets it go right on around, nothing stops the cam from going in either direction. going to video it. |

Note- such a design could prevent the need for stator upgrades in some situations.
and with so much led stuff out now for most of the lighting including headlights, drastically reducing the power consumption, i think stator upgrades aren't as needed as they once were. even for me, it's mostly because i have wanted to for a while, not that i currently needed to.

i hadn't noticed that before but then it wasn't in my thoughts when in there. that said i just went played with an old one of mine. trying to say this right so bare with me
the piece on the rockers he pointed to is what the piece you pointed out sits against during normal rotation and otherwise doesn't move (it's stationary and the cam turns freely in it). it (your part on the cam) IS one way like a good open face reel, meaning when i turn the cam backwards it goes with it and doesn't slip BUT, as it comes around full circle the stopper on the rocker assembly is spring loaded (in the reverse direction) and allows it to go right on by, so in essence, there still seems to be nothing it's actually doing. Again, maybe it's a high speed thing that i can't duplicate with just my hands turning it, but as it sits it in no way affects anything.

i've heard different things about these such as keeping it from running backwards, which makes zero sense, but maybe for kickback, though not to stop it, just to keep from slamming the carb and with high pressure air when it happens. heard horror stories about turning the engine back even a little (for maintenance purposes such getting TDC) as mentioned above and it is very hard to disengage bla-bla but never once has it given me a single problem when adjusting my valves and i have to turn it back some almost every time. whatever it does i think it needs high speed and turning the engine by hand doesn't count. i have looked right at it while doing this and it has never moved or affected my rocker arms.

yes the big one. it does sound as if during decel it is not keeping enough tension on the belt which is needed to keep pressure on the variator and whence keep the sliders in place. it may be rusty or the inner sleeve is fouled. i had one that would get a bit cocked and not close right.

tvnacman, i think you mean the crank does 2 strokes for every one compression stroke. at 1000 rpms we are only getting 500 compression/combustion strokes but the crank and whence stator see all 1000. these actually send a useless spark at TDC of the exhaust stroke also, due to the trigger coil having no choice but to send its signal every revolution.

now i have to go find the pic of the stator that matched your illustration pic for three phase which happened to be the first one i looked at and now can't find. maybe my counting was $#!@, haha . what could the odd pole be for? due to the fact each leg makes the same voltage, they would have the same number of poles (3 each, and the same number of windings per pole). does the forth have maybe all three phases wrapped on it? it's the only thing that makes sense to me but it really doesn't.
