See my post on "Let's talk belts". My belt was loose and slapping. Turned out to be the rivets on the clutch pulley were all coming out. This let the two pulley plates flop around so the belt wouldn't come back to the top of the pulleys at rest. Don't know if that's the same problem you had but it took me awhile to find it.

In attempting to figure out why my belt was slapping, and getting worse every day, I took apart the variator. My thinking was they weights weren't moving out fast enough. Cleaned all the Chinese tar out of there and put it back together and it didn't make any difference.
Next I decided to take the clutch end of the drive-train apart. And that's where I found the problem. They used rivets to attach the aluminum pulley plates to the stainless main assembly. One rivet fell out in my hand, 3 more are hanging out 1/4", and the other five are flopping around in there. The inside end of the rivet extends through the pulley plate to where the belt rides once the clutch engages. The edges of the rivets where like teeth, grabbing and chewing on the sides of the belt. Both pulley plates are barely held on and just flopping around.
So now I need to replace the clutch/pulley assembly and the belt since the sides of it are all chewed up.

I measured the belt today and it measures 22 mm wide. Could the slap be caused by a problem with the variator? Like if the rollers didn't move out quick enough? If that happened the pulley by the clutch would be opening up before the variator took up the slack thereby making the belt slap. At least that's how I'm picturing it happening.

I have the exact same belt in mine. Recently I noticed the belt is making a slapping noise when I accelerate from a stop. I'd have to accelerate until it starts slapping, ease off the throttle, then accelerate again to get it up to speed.
I pulled the CVT cover off and I can see rub marks on the top and bottom edges of the cover, like the belt is slapping against it. The scooter only has 3000 miles on it so I can't believe the belt is worn out.
Any ideas what can be causing the belt slap?

Looks like you guys were right. Rode home Friday during a terrible thunderstorm, high winds and heavy rain. Noticed when I stopped to put the rain suit on that one headlight wasn't working and thought "uh oh, that's what happened when the voltage was low last time."
When I finally made it home I checked the voltage and it was down around 11.5 with the lights on and fan running. I put it back on the charger last night.
Guess I'm gonna have to order a new regulator like the one Damin bought since that seems to be a big part of the fix. Has anyone posted info as to how you wired the relay that replaced the diode? It would be helpful.
Thanks

After reading the reply's, did the 30 mile drive from work to home yesterday going into a pretty stiff headwind. Temp gauge was just below half way up all the way home. Fan was also on. When I got home I checked the voltage and it was sitting at 13 volts with the engine off.
It is the original battery so that may have something to do with it. I do 60 miles a day and haven't noticed any slow cranking or anything due to low battery voltage.
I'll check the voltage again this weekend.

Not that I've noticed. Still getting around 68-70 mpg.

After fixing a problem with my scooter that I accidentally caused I was sitting here reflecting on things I've learned since buying my scooter. Here's what I came up with:
1. Companies with big flashy websites that sell scooters and have lots of pictures and really push how nice the scooter is and are willing to talk to you all you want pre-sale can often forget who you are and how to answer the phone or email when your scooter arrives with some broken parts.
2. Filing a complaint with the Better Business Bureau can suddenly light a fire under the butts of the same company and make your replacement parts magically appear on your doorstep within a couple of days!
3. Small tires make a 1" tree branch feel like one of those concrete parking lot bumbers.
4. Raindrops can hurt.
5. Changing your own tire isn't as hard as it looks. And the money you would have spent having someone do it will by a nice bottle of tequila.
6. When you do an "upgrade" that somehow causes the scooter to not run correctly your wife will always be there to remind you that it worked just fine before you tinkered with things.
7. Bugs can hurt.
8. Riding this thing is so damn much fun I wish I would have done it 30 years ago.
9. Total strangers will wave at you because you now have something in common that transcends all other social barriers. They will also pull up next to you at stoplights and ask you 20 questions about your scooter.
10. There are people on Scooter Doc that are willing to help you out when you're stumped.
Rock On people!

Here are some pics of my 250.  I extended the windshield up 4" and it made a world of difference. Less buffeting and I can hear things now.  The sweet decals and strip lights I put on the front end.  Decals on the rear and the belt cover.  The bike overall, pardon the messy garage.  The mount I installed for my HTC Evo 4G phone. I can use the Sprint navigation as well as play my MP3's through my helmet via Bluetooth. |

The charging problem is solved. After thinking about it all day I decided that I didn't have the problem before I put all the new lights in so the best place to start would be to disconnect all the lights. I had charged the battery overnight so it was at 14 volts when I started tonight.
I disconnected all the lights in the fairing, hooked my meter to the battery leads, and started the bike. Sure enough the meter showed 12.98 volts and as I brought the rpm's up that climbed to 13.5 volts. Let it idle back down and it went to 12.98 volts. Then I started plugging lights back in. No change until I plugged in the HIDs. As soon as I did that the voltage started to drop until it got down to 11.2 volts. Disconnect the HIDs and the voltage climbed back up to 12.98 volts.
When putting the harness together I had used crimp on butt connectors because I was out of heatshrink and didn't want to use tape. I had brought some heatshrink home from work today so I cut the connectors off and redid it with solder and heatshrink. Put it all back together, started the bike and sure enough the voltage went right up to 12.98 with the lights on.
Spent the next hour or so putting the whole scooter back together and took it for a quick ride. When I got back checked the battery and it's holding at 13 volts.
Thanks for the help and suggestions. Now I'll go post pics of the pic in the correct area.

Thanks for the suggestions so far. I'll post pics of the scooter once I put it back together.
I came home tonight and took all the covers off. Checked every plug I could find for loose connections. Found a couple of wires in the plug from the fuse box that were pushed out and barely connected. Fixed those but no change. I printed out the wiring diagram and traced the wires back. Best I can tell I don't have the diode on mine.
Here's what I've found so far. In the picture I've got two devices with heat sinks mounted on the right side of the scooter. I'm assuming the larger of the two is the regulator, not sure what the smaller one is. Put the meter on it and it doesn't show continuity like a diode would but it does show 670K ohms of resistance. With the engine running I'm reading 12.2 volts on the red wire and 11.5 volts on the yellow wire to frame ground. The yellow wire shows roughly the same voltage as I get across the battery leads.
If I measure the voltage on the red lead coming out of the regulator I show roughly 13 volts +/- .2 volts which is what I think I should be showing. That wire goes into the harness and I believe it goes up toward the front of the scooter, ignition maybe?
So does this give anyone any ideas as to what to check next?
Thanks again for all the help.

I've got a 250A and loving it. Put 60 miles a day on it round trip to work and back everyday. I'm now at 1700 miles and only had it for five weeks!
This past weekend was upgrade weekend. Put on new Michelin Pilots with Dynabeads. What a difference in the ride. Also classed it up with pinstripe decals from PurpleHarley.com that were a breeze to put on and they look great.
I swapped out all of the lights with LED's and installed these HID lights from Ebay....All of the lights worked great and look fantastic. Can see really well at night now which is much needed since I live in the country. I took it to work today and as I pulled up in the parking lot I notice one headlight was out. I shut it off, reached up under the fairing and reseated the cable, and went to start it again. The fan came on but it wouldn't crank.
I pulled the battery out and brought it in the office. The voltage on the battery was at 11.5 volts. Charged it up to 13.6 and at the end of the day when I put it back in she started right up. When I got home tonight I put a meter on the battery while it was running. At idle I'm only showing 11.61 volts. When I run the rpm's up to about 4000 the voltage only goes up to 11.85 volts. I don't notice any dimming or brightening of the lights when the rpm's change. It seems like the voltage is low by a couple of volts.
I can't see it being because of the lights since the led's should draw less current than the old bulbs did. The HID's are the same wattage as the originals so other than startup current they shouldn't draw more either.
Any ideas? I'm running the original battery but I can't see that having an effect on the voltage at the terminals while it's running.
I'd appreciate any help I can get on this one.
