When we convert to V5 it will probably be on 11 or 12pt. It is coming upon us soon.

It's not always the torque amount, we forget that they generally use some form of Loctite and when you put a bolt/nut of any steel grade in aluminum and/or steel with that on over time it will seize in a real hard way to get loose. I don't think they know what "blue" Loctite is.  JR |

Well there are worse things than hard headed and again from reading all this I believe this is just a misunderstanding? Like was stated we call a scooter AC or DC by the process of how the engine fires, is the CDI Ac fed or DC fed? He has already stated that the engine will run without battery power and again the 11 pole stator is AC.
But from closely reading this I think his assertion is his "charging" system is DC? It is as in "yes and no" like all scooters are. Stator produces AC and is converted to DC by a half wave rectifier joined to a regulator. It's easy to confuse this.

He will read nothing, the 11 pole stator puts out AC on the black/red wire and with the scooter not running he will read nothing and if he does test it with it running he will need to set the meter to AC. There would be no need to change the CDI even with a 11 pole stator upgrade, one would have to run a wire from the ignition black wire to the CDI and then tap the black/red Ac wire off. IMO a waste of time and money. Also with the 11 pole stator upgrade one has to either put a cut off switch on the head tail light system or use a relay which is the most common choice. By using a relay you have lights immediately with the engine running. It would be like this relay diagram and the head tail lights would go where is says LED on the relay.  |

My battery has been dying on me a lot lately for whatever reason so I dont think its getting charged I have a totally dc setup with an 11 pole stator and 7 pin reg/rec so my question is how can I test my 11 pole dc stator to see if its putting out the juice it should be I tried hooking up a voltmeter directly to the battery and revving it up and the numbers looked good so I thought it was alright Im not sure what else too look for? Is there a way to test the stator or reg/rec to figure out where the problem could be? Maybe I can clear up some of the confusion and answer your original question? First of all I see in your signature you have the 150 Roketa a 07 model and it did not come with an 11 pole stator so I have to presume you did the 11 pole stator with the 7-pin R/R? What I think the confusion is what is really AC or DC? When I say a scooter is AC I mean the CDI system is AC powered and the scooter will run without the aid of a battery or stator charging as long as the CDI dedicated coil is putting out the necessary AC to the CDI and the pulse coil is good. DC systems are those that have 12Vdc supplied to the CDI via the battery and will not run with out this DC voltage and if the battery slips to a low range of under 10.5 Vdc the engine will not start or run thus the charging system must work to keep the battery at the voltage necessary to power the CDI.  The 11-coil stator is AC. It has 3 yellow (charging wires), ground, a pulse coil and CDI feed wire. DC powered CDI systems will only 3 charging wires, a ground and a single pulse coil wire going to the CDI. The CDI power comes for the battery. Now you asked the proper way to test the stator and R/R. Since the 11 pole stator is 3-phase you test it's output which is AC by checking the voltage from one leg to another and in this case the 3 yellow wires. The voltage must be the same on all 3 legs and the test should be like this: Wire 1 to wire 2 Wire 1 to wire 3 Wire 2 to wire 3 At around 5k RPM the legs should read from 60 to 80Vac. If the system is properly wired then testing the R/R should be done on the red wire going to the battery and at idle with a full load, (lights, etc.) it should read in the range of 13Vdc. At 5k or better it can and will read 14.5Vdc with a good fully charged battery which leads me to another point. If the battery is a little on the low side the charging will increase, why? On the 7-pin R/R the black wire to the ignition reads charging demand and if their is a bigger load or the battery is NOT fully charged it will increase voltage output. Remember R/R = REGULATOR/RECTIFIER. The 11-pole system is a AC output system but is like other scooter startor R/R systems the final result is DC to the battery and accessories. The typical scooter charging system uses a half/wave recticfier while a true DC system uses a different stator and a full wave rectifier. One can actually do a full stator DC conversion but if you do so then you must use a full wave rectifier. gallery.trailtech.net/media/instructions/lights/stators/AC-DC_Banshee_Stator_Conversion_Instructions.pdfwww.trailtech.net/regulator-rectifierAlso floating or no floating the ground is not a indication of a DC system. Full wave DC charging systems are not practical or cost effective for scooters or it would have already been done. Even the motorcycle DC conversion kits hit $400+. Now if you are staying at 14.5 or so at a higher RPM with a amp load on it you'll be OK. I don't know if you use LED's or not but by going back to standard old 1157 bulbs you can add some amp load back to the system and help with over charging if that's what you have. Also putting the auto choke on the white wire will add more amp load. Heck put you a radio on the scooter. Worse case scenario is go to Radio Shack and get a resistor or two and shunt some of the extra power to ground just like your R/R does. JR |

If you actually have the 250 "B" then it's linhai and the first order of business is adjust the valves. Dying, hard starts all classic valve adjustment on this engine. How many miles on it?

I just discovered by looking at the videos all posted on You tube and found that they were all done in 2009. Over four years ago and I searched long and hard and haven't found another Public Safety Warning as they called it since? Seems like a dealer here on this thread mentioned something about the Chinese coming a long way in the last few years? I also remember the market being flooded in 08 and 09 with Chinese scooters due to the $4 a gallon gas hike. Seems POC has went silent since then? JR So now we have the context of 4 years ago....would you now say he was telling the truth?
he's trying to hoodwink the public....Not a good way to stay in business very long.If you see a guy condemning other products as a good business practice instead of standing on his own merits then I'll question your own ethics and call you very gullible. You watched a video of over four years ago to try to convince people here in this thread that Chinese scooters are junk and then telling me I think he's lying because that's what I want to believe? So I decided to watch another one of the videos: Now remember his introduction to every one of these, Hi this is the Pride of Cleveland bringing you another Public Safety Announcement. Scooter came to the shop as a "non runner" Broke cable, rusted chrome and wasn't running. How can a scooter that WILL NOT RUN be a safety hazard? You believe based upon you just think he's telling the truth and it's good business? As far as the maker of my scooters they are made by three different companies and we couldn't compare them to this scooter because he never told us the maker of this scooter and before you start just because a scooter is called say a Roketa doesn't mean Roketa made it, in fact Roketa makes no scooters at all and I own one of them. This shows your own lack of knowledge about these scooters. He also said the scooter that would not run was made by Roketa. Again Roketa is a seller, they make nothing. You seem to want to make me admit to something that you believe in and want me to come out and say someone is doing this or doing that? I said it was a sales hype and for whatever reason with very little proof you have just jumped on board to say this guy is helping the public and being a good honest dealer with no reason to bash these terrible scooters. Why did he stop making videos? Have all the junky dangerous Chinese scooters all of a sudden disappeared? Surely not? BTW since you seem to believe people in videos that you know nothing about and just see them as good old honest guys with no reason whatsoever but to help people stay safe from products that we don't have a clue as to who owned them, how they were maintained or treated, would you like to buy some swamp land in Arizona? What you're saying makes just that much sense. I think the purpose of this thread has been served and has no reason to go farther. JR |
