Both your taillights should be on. Could be a bad bulb or a problem in the bulb socket. A multimeter is almost a necessity when trying to track down your kind of problem. Harbor Freight has a basic one for around $5. The green wire is a ground wire.

Sorry to hear about your boo-boo Josh. I have a feeling that you will have a problem refinishing the plastic after being hit with the brake fluid. I don't think it can be cleaned enough for paint to stick to it.  |

It annoys my family that I don't have the preset buttons set to stations in my car. When I drive I spend the time listening to the engine and road sounds and check to make sure nothing changes. In between I'm contemplating and enjoying the scenery. Pretty much the same when I ride the bike or scooter or the mopeds. Love the sound of good running engines. 100% with you, kz. |

Hi Chris, if you have a fuse box like this located next to the battery:  then you will also have to check the connectors inside the box that the fuses plug into. They tend to push out of the bottom of the fuse block which results in an intermittent or open connection. Like having a blown fuse. The wires have to be pushed in from the bottom of the fuse block until they lock in place. Some people have found it necessary to replace this fuse block with a quality one in order to avoid opens and intermittent connections. Also, my scoot has a 15 amp in line fuse coming off the battery instead of a 20. |

Hi Chris. It sounds like a blown fuse or a bad connection at a fuse holder. The OEM fuses are also of questionable quality and have been known to be open even when they look good. A loose connection on a 12 volt line could also cause this. This is the type of scoot that Dr. JR is a specialist on. He will be able to give a more detailed analysis when he reads your post.

My CVT gasket is rubber also. I put a few dabs of silicon around the edge of the gasket to hold it in place during removal and installation of the cover. Shouldn't have to ever replace this gasket as it's pretty durable. Another reason to keep the rubber gasket on would be to help reduce noise since the rubber seal helps isolate the large CVT cover from the vibrations of the engine.

Roller weights don't really roll or they wouldn't flat spot. Once they flat spot, then they start losing performance. Rollers seem to work best if they can really roll so some lubrication is required to minimize flat spotting. Too much lube will make a mess in the variator and possibly get on the belt. Too little lube will result in flat spotting and you will lose the smooth operation of the variator.
Sliders are made of a material that doesn't require lubrication and will give a wider operating range over the same weight roller weight. I have had very good response (fast and smooth) with my 19 gram sliders. I also sprayed the weights and the inside of the variator with a dry lubricant (Jigaloo) which may help with the smoothness and response.

Thanks #1 As I seem to have a lot of hoses going all over the place and it does say the magic word California on it. I guess that is the reason why I can't find the A/F screw. The scooter was purchased from a CA company. The A/F (pilot) screw is located under the inlet side of the carb. It's covered by a metal or plastic cap which has to be removed in order to adjust. mpsracing.net/helix-manual/04-07.html |

The OEM roller weights that came with my YY250T (Helix clone engine) were 23.5 x 18 mm. I recently got a complete variator set on a good deal and the installed weights were 23.6 x 18 mm. It looks like a true replacement weight (23.5 mm) doesn't exist unless the 23 mm advertised is really a 23.5mm?
I installed 23 x 18 mm sliders with excellent results. If anyone has installed 24mm weights in there 244cc scoot, it would be interesting to hear the results.

Possible that the spark on some scoots is weak enough where you have to compensate by using the .5 PPR setting. I wonder if this would change with a high output coil.
