For some time I have been plagued with battery charging issues. I have an 11pole ac stator (new) 6 pin regulator (new). Both replaced about a month ago and all was fine. I put on a new stator as I thought this might be the stem issue as regulators are only a temp fix. Now once again, I have battery charging issues. output to the battery barely reaches 12V when idle and never gets up to 13+ at higher RPMS Is there another electrical part that could be the culprit? Scoot starts fine when the battery is charged, but after 7 mile ride to work, battery is at about 11 volts (newer battery as well) This has been a recurring issue for that last 4 or so months. New regulator = charging for a couple of months and then  Any comments suggestions? |

Have not been able to correct my noise issue (Help! Valve issues) on my 161QMK-A engine and since this is my main transportation, I can't take any chances with it failing.
I've decided to replace the engine with a new 150cc short case (downgrading), since I can't seem to find a replacement in my current size(168.9cc).
So my main question is regarding the electrical, namely the voltage regulator/rectifier. My current engine has a 11pole AC stator and regulator that goes with it. All of the new engines I've looked at seem to have an 8 pole stator.
Electrical diagrams make my head spin and trying to figure out if the current regulator will work or what I'm going to need to do.
I have a brand new 11 pole on the scooter so I'm thinking of swapping the new engine with this one and the magneto rotor. OR should I leave the 8 pole on and will the regulator still work?
My current regulator is 6 pin and I have only been able to find one online that the wires match Exactly (3 male-3 female) in the same color-wire sequence. While there are other 6 pin regulators out there the sequence of wires are all different.

getting a new engine as I can't afford to have this thing blow up so to speak. once I get the new engine in, I'll tear this engine apart and see what the issue might be. Will be a good learning experience to tear it apart and see what makes it tick, so to speak. and If it is something I can fix, I'll have a spare engine...
Really didnt want to have to, but my scoot is my main transportation so could chance another major breakdown.

check the cam bearings and valve lash. John Both are fine. I can't see how either would make this noise |

I'm listening to it over and over........ and over Lets give it a few. the video is good just really hard to make a call.. thanks! truly appreciate it... |

here is the best I can get without getting the camera in the variator. with the CVT cover on you would swear it was a roller bouncing around, I took the variator off started the engine and still the same noise. it sound like something is bouncing around inside, somewhere. when you rev the engine it gets less noticeable but still there. If you put a marble in a jar and shook it up and down, it would sound the same It never made this noise before the original problem. |

Pulled the valve cover and looked down into the engine and chain and guides all seem to be where they are supposed to be... So i know everything there is correct

From what you indicate, Its running to darn good to take apart. Clapped out Cam Chain Guides to the point the assy makes noise I would cause inconstant tune and one would notice this. Can you Video up close? video of what? Thanks! |

pistonguy I had a race car mechanic listen to it with a stethoscope (Luckily one next door to where I work) he said the engine sounded fine! But the noise is driving me crazy. something is not right somewhere... and I'm afraid to drive it for fear something major is going to happen. I've checked TDC and it is fine, I've pulled the variator off and started it and it still makes the same noise, so it's not a bad roller or anything. The chain issue sticks in my head - when I was setting the piston to TDC the chain slipped off the sprocket inside the engine, behind where the variator sits. I put the chain back on the sprocket and went on my way to putting it back together. It is in THIS area where the noise is coming from. It is as if something is loose and rattling inside. Ok cool on the mechanic listen. A noise of what you explain in the internals would Most Likely caused a Failure by this point. Hold off on taking it apart..... Do a run thru check of the time chain tensioner as you looksee with the Valve Cover Off. I would think if the CamChain is flapping round in there its more then enough to jack up Cam/Valve timing and would run poorly, but on the other hand you say you quad checked the TDC Cam timing and is Correct?? Yes I've checked TDC by pulling the spark plug and watching the piston and it coincides with the mark I put on for TDC. the engine runs great which make me believe it is right on the money. The chain is tight, the cam chain tensioner seems to be working as it should. |

here is a pic with my finger pointing to where the noise is coming from  |

the sound is coming from no where near the exhaust. it is coming from inside on the bottom, right behind where the variator is and where the chain sits on the sprocket. I've pulled the exhaust 3 times and a mechanic with a stethoscope listened to it and assured me it was not the case.

If you were off one tooth either way it would not start or run as good as you state. Don't take it apart........ Use the Mechanic Stethoscope, a Long Screw driver directly to your ear. you can isolate the noise better that way unless you have or could borrow a mechanic stethoscope. I had a race car mechanic listen to it with a stethoscope (Luckily one next door to where I work) he said the engine sounded fine! But the noise is driving me crazy. something is not right somewhere... and I'm afraid to drive it for fear something major is going to happen.

So I've been trying to figure out what this noise is and now I'm thinking that maybe it is possible that I am not at absolute TDC? The scoot starts and runs good, but is it possible everything is NOT set a TDC? Which could be the cause of the noise?
I'm getting ready to take it apart again, but really don't want to if I don't have to... I've read so many conflicting instructions about where TDC is really at on these engines. I thought the piston was at tdc when I put the head on but now I am questioning it. If I was off one tooth, would it still start and run but make this noise?
Desperate to get this resolved!

I thought that was the problem as well, but they are brand new and I pulled the variator to check and all was fine.
