Tough to tell what that sound may be in the vid. If you can, take the variator off and see if the sound is still there. I remove the vari stuff and belt then install the nut and use an electric drill in reverse to start the engine. Even in person I have trouble figuring out where noises are because everything is so close together, so this eliminates the whole CVT as a potential cause. I found this interesting. Notice the difference in length. Both NGK. The BP7HS I was buying is longer at the electrode end than the BR8HS... I had a few electrodes get smashed down to 0 gap using the longer with tight squish clearance. No worries with the BR8HS now... Got them at Advanced Auto for $3 or so each... The P in the plug code is for projected tip. Right. I'm pretty sure I did this in the very beginning though, I removed the vari and ran her for a couple minutes. That's when the noise was louder. Now I have a new issue. I just put a BPR7HS NGK plug in it. She started up and was running for a few. So I threw on the helmet and was going to take it for a quick ride. I flipped up the kickstand and it DIED! And now it won't start. It turns over, but it won't turn on. FML This thing really is going to be the death of me. And I don't have the damn time, energy or funds to keep fixing it. I was about to order the Stator, Rectifier and a couple nuts and bolts for it today. Now I have to figure out why she won't friggin start. My suspicion is the bowl is full so I'll try and drain that first. I remember last time it did this, when I cleaned the carb she fired back up. Now I dunno. I seriously am contemplating selling it and just getting a TaoTao with a few little mods/improvements now. I can't keep working on this thing and giving the GF a chance if she'll make it to work or not. |

Sorry, I was too lazy to go back and look and didn't remember. In that case, you've eliminated the CVT as a cause of the noise. You don't see a problem with the pickup and releuctor. I did have one of mine recently make a noise and eventually die on me and start running odd intermittently when the stator itself came loose on the plate it mounts to. Otherwise you either have an exhaust leak still or something is knocking inside of the engine and it'll prob be tough to tell what without some disassembly.

Otherwise you either have an exhaust leak still or something is knocking inside of the engine and it'll prob be tough to tell what without some disassembly. No worries. Yeah, I'm starting to think it has something to do more with the stator now. So my wanting to order and install the new one just got more of a Need at this point. I'll show you why below. I got this cheap tool from Harbor Freight and haven't had a use for it in a long time. Well it just dawned on me, why not listen for where the sound comes from? I remember my dad using a brook stick to hear which piston was not firing or where the grinding sound was coming from an engine. Thanks again dad, even though you're gone you're still teaching and reminding me old school stuff. So I used these and it sounds like a high pitched noise coming from the case right where the Stator is. I felt along different spots. Intake, the case by the CVT also had some of the noise but it was much more evident along the Stator side. I took her for a spin. Seems like I can never get the idle to stay steady. When she's cold, she's rough to keep running. Choke maybe? Should I replace that? Once she warms up, I can lower the idle screw back and keep her around 2k rpm. Oh and yes, the stator is all connected as normal. Funny thing, with the battery charged, it doesn't seem to lose voltage too much. It just doesn't go up. Here's the tool. I dont' care if you make fun of me for it, but it works.   |

But yeah, she went barely 35mph today according to her speedo. *sigh* I really do wish I had the time and resources to get this thing tuned in and checked right myself but I don't. Sadly I think I'm going to check out this ad on CL for a guy up by me that does work. He charges $55 an hour so god knows what it will cost but if he can figure it out without the GF being without it for too long, then yay.

Did you check the ignition pick up for contact with the flywheel? There isn't any moving parts to make a noise on a stator. I wouldn't take my scoot in for that kind of money. You can drop it off here and I'll look it over after work. GF would be without for a day or two. You said the noise went down with the exhaust gasket change. It's odd that the noise is still there but less after putting a gasket in it.

I wouldn't know what that is or what it's supposed to look like without finding pictures or videos really. I may as well be trying to work on the space shuttle at this point, I don't have the patience or even the luxury anymore of being able to wait for answers and troubleshooting on here. It's a 2nd vehicle for us, her primary for getting to work. I spend less time with the GF and more with this thing when she's off just so she can get to work only to call me with more problems on it. I'm getting closer to selling it along with those other 4t scooters I got now, really. *sigh* |

Niz posted a pic for you. OOHH! That part! Yeah I looked. The bell has one notch on it that looks like it's for the pickup and it looks fine. I can free spin the fan/bell by hand with very little force mind you. Not sure if that's good or not, even for a little 2t motor. I dunno, the noise seemed to be coming from that side mostly. Maybe it's a bearing that just is goofy at low rpm? Should I look into having someone to a rebuild on this thing? Hell, I'd give someone the two scoots I have PLUS I'd buy parts for them to pay for the labor, just to have someone that knows what they're doing to tear this thing apart. I'm really running out of time/space/patience/resources. If someone came to me and said "Yep, spend $300 in parts right now and I'll have it running top notch!" I'd throw my credit card at them faster than a bullet. Yeah it's fun learning stuff about them and all, but when it's a primary vehicle for someone it's rough as hell to say "I'll just fix things as they go and hope she runs." |

I've only got a 1 car garage with 2 scoots in it now but I'd be willing to go through it if you dropped it off. If it's a bearing you'd be without it for a bit because I'd have to pull the motor and split the cases. Did you notice if the raised strip on the flywheel was making contact with the pickup?

Just had a whole message typed up, got an internal server message and poof the message is gone. *sigh* Anyways. I wouldn't think of asking you as I know you've got your own projects and space restrictions for your stuff. But if you wanted to, I'd be willing to work with you and even buy some parts for you for your time even. That's up to you though, you have the garage, not me.  As for this thing being gone. Honestly I'm ready to just buy a cheap Tao Tao or something for her. Local places want a grand or more for anything new, online I can find stuff for under $800 which is what I can afford to throw out now just so she has something. If the scoot doesn't work, she has to ride the bike. If it's raining, she's screwed either way. If she has to go beyond work, I make her take my car and rent one for the day because I don't trust the scooter going too far right now. |

You might be better getting her a new scoot. Not that your scoot can't be made to be very reliable, I haven't seen anything that scares me from it. No offense but I like working alone in my garage. It's my peace and solitude, even with grinders ringing in my ears and aluminum all over the place. I work in sales with the public, contractors, designers and a bunch of other pita's so this is my relief. Besides two people working on one scoot in my garage, well it just wouldn't work. I'm happy to do the work for you if you want to drop it off. I won't take your money or anything else , you buy the parts if I don't have them. If I do than we'll work it out. I can't ever imagine needing a stock cylinder or crank so there are things I'd be happy to donate. It's up to you.

Believe me, I'd much rather hand it over to someone and say "Here, fix it!" lol. Well then, maybe we should talk. I'll see if I can get her brother to let us borrow the truck for a day to get it there. Meanwhile, I'll hit up a local place or two for a scoot to get her for the time being. There's a place in North Palm I've been talking to. Not very fast at responding, but she has a ton of stuff there and she even sells some used. So I'll get in touch with her and see what she has. Maybe the GF will have to deal with 35mph for now, at least it will be more reliable that this beast lol. If you really want to do this, I'd be very greatful.  |

Renting may be costly depending how long Christine will be in the "shop" for. lol Jupiter Scooters, that lady is kind of crazy. She wanted $1,200 for a Baccio or something that I could have gotten online for $800 I think. I dunno, she's a bit higher than my credit limit would allow though. But I'll give her another look and see if her inventory has changed. |
