After several frustrating weeks of literally part after part failing on this scooter, it's alive again, lets see, this all failed almost at the same time: stator, CDI, coil, a tiny piece of fuel filter got into my main jet, Bendix failed, then my starter, then the battery, and the converter muffler failed due to it clogging, turn signal relay, belt, variator rollers, and contra spring, plus the disaster of Amazon trying to get me my stator, three lost in shipping, one disappeared in Jacksonville, one was heading for Alaska, the first stator they sent me was a complete , I finally searched by rating on line, and came up with X pro, and it turned out to be an excellent stator. I have some oddball advance on mine, so a regular cdi doesn't work, I had to order one from a chinese parts supplier in England, OEM , I ended up buying a Yamaha coil and wire, much better then stock, got a new bendix, then the starter quit, The one I got on Amazon cranked better then OEM, very happy with it. I made up all new 6 gauge starter and battery cables, I got a Hoca blue contra spring, the blue seems to work best for me, Doc Pulley 6 gram rollers, a gates powerlink belt, it was 30 bucks, but I'm tired of frying belts, I heavily modified the muffler case then welded in the shorty cherry bomb, I love the muffler, it really changes the personality of the bike, and it revs much more freely , just took it out, rode 10 miles, other then I have to fiddle with the idle mixture, it runs like a

Good idea running the Yamaha coil,,,much better quality,,,faster recovery time and a hotter more consistent spark,,,also the cables you made up were awesome and I believe helps in the big picture chain of events,,delivering clean big power,,,,really nice,,,(edit),,,glad you got it sorted out,you sure had your work cut out for yourself,,,

Great you got it going again! 6-gram rollers? It should accelerate like a crotch-rocket! You may (or may not) need to go a tad heavier once you try riding near top-speed. I tried 10-gram rollers in my old Xingyue 150 and it took off like a rocket, but topped out at 45-mph at over 9,500 rpm! I tried 12-grams, but lost all acceleration and hill-climbing power, but attained a 63-mph top-end. I finally ended up mixing three 10, and three 12-gram rollers staggered for an average of 11-grams and that was the perfect setup, giving good acceleration and a top-speed of 60+.
Of course, THAT was my individual scoot. Each one responds differently. You'll get it perfect pretty quick now...
Ride safe!

Well it's just a simple winding but it wuit, the one with the other stator was bad out of the box,I had to put in my original one, looks like it's going to have to go back in again. Apparently a lot of these fail, of course the simple non moving part goes. I can understand stators failing as they generate heat, but these sit outside the flywheel. I did notice when I unwound part of the bad stator, that the copper is not ductile like in good windings, but very brittle. I've rewound motor windings before. And this is very poor quality copper

three pickup coils later and I still have no ignition trigger, I have 145 ohms or close to it on all three, installed, but no output voltage, I'm going to go out with a neede file and elongate the holes, to see if I can get them closer to the timing mark

I did not know it was a YB50. (Also known as the FS1 in the UK, or a "Fizzy")

it, I had it running, no lights, tore it apart to replace the stator plug, now it won't start again, I've had it with this dam , the entire ignition system and stator is new, the fuel system is new, I've been out there in the freezing rain trying to fix it, it's laying in the mud where I kicked it, and that's where it's going to stay. I will never buy another Chinese scoot, 200 dollars in parts, and two months and it still won't run, I've had it

DO NOT tinker with a future replacement scooter . . other than routine maintenance! |

It comes made of cheap Charlie parts, the battery,starter,belt,variator,carb,brakes,bearings,stator,intake,fuel petcock,clutch spring,all failed by 2000 miles,the wire crimps fall off,plastic parts crumble in my hands, there is a lot more that I'm fogetting
