I have a longcase 50cc. Got the orange torque spring installed, everything else is stock.
Im only reving to about 5300rpm wot, max speed.
Scoot launches around 2309rpm, if i want to rev higher and launch at a higher rpm i need stiffer clutch springs, and lighter weights correct?

It sure sounds like you need to look at clutch pads and springs which hold them together. They are a very simple system so go for it Trying blue springs in my ride tomm... Cant wait to see the difference accelerating from ~3k rpm instead of ~2k... |

I would definitely try SeaFoam or another fuel additive before tearing into the carb or head. Terrible advice. These engines have nothing to gain by using these additives in them... Easier/cheaper to run ethanol-free gasoline, and clean the carb before every riding season, or once/twice a year if youre lucky enough to ride year round. |

Hello I have a 2004 vento 150 scooter doesn't change at 2000 rpm I noticed the horn doesn't work until till it runs for 30 minutes.i plan on replacing the battery next week because it's over 3 years old . do I have a voatage regular going bad ? I replace the stator 2 years ago. The battery will charge but not enough to Crank the starter and has a week Horn a couple hours later scooter battery will be dead just sitting. Thanks Larry Sounds like you may have a bare wire somewhere grounding out.. check wiring, replace r/r and battery. |

I have a 2016 atm50 that I just installed a 80cc bbk last week. It's been running great until tonight. I took off from work and when I hit 10mph it started sputtering and backfiring until about 20 - 25mph then it took off. Did this every time I had to stop and start. Got it home and took it inside put it up on center stand and it did the same thing with no load. Also I noticed a slight flickering of my dash lights. This is a brand new engine that i installed the bbk before i even ran it. New carb with a  jet also. Something else i noticed. There was a slght flicker of my dash lights during the backfire and sputtering. Any ideas before I start blindly taking it apart? Thanks guys. Sounds like your carb needs adjusting. Try adjusting needle position out one slot. Edit: noticed you said it was running fine for a week beforehand. Check to see if your jets are tight. Had an idle jet work loose on a new carb before and showed these symptoms. |

I have a Evo 2x big powerboard . When it is off the ground and I pull the throttle the wheel spins but when I stand on it it barely moves an it only moves when I pull the throttle a little. If I pull the throttle all the way I get full rpm's but no acceleration. The clutch drum still spins when the wheel isn't moving I don't know if that is relevant. Anybody please help I need my scooter to get back an forth to work. Belt slipping? clutch pads gone/worn away? |

Not sure. I did a search and they popped up being made in America...either North or South but America. Heedehcheenuh Chuck D Ride on..... Bando it is then... Hopefully it'll hold up to the stress of my bbk and cvt mods... And later the butane/nitrous injection i got planned *evil laugh* |

Look up Bando. It is about the only American made belts left out here. Heedehcheenuh Chuck D Ride on..... I thought bando and gates moved to china too? |

Good luck on your quest. I don't know if anything is made here at home anymore. That being said.....I have no problem putting a 'Made in China' belt on my Chinese made, 150cc scooter. My last Gates Premium had that stamped on it, and I ran it 6,800 trouble free miles. No fraying, no cracks, but had lost a couple of millimeters in width. Replaced it with another just like it....stamped 'Made in China' also, and it has now run something over 4,600 miles....still looks good. I know there's a lot of crap that comes from there, but not everything produced in China deserves that label. Being from a manufacturing background myself I just prefer to support american jobs whenever possible. Im not saying everything fron china is garbage. On the contrary. They have a booming and emerging manufacturing industry there that is slowly becoming decent. With that said, anyone know anythibg of the red DLH "racing" belts? |

True. Get a higher wattage bulbs(55w for 150cc i beleve), if those blow, replace regulator/rectifier. I read the same thing.. tried brighter bulbs with same result. I looked into this rectifier thing at one point, thinking maybe there was a resistor or something I could install. Not sure if there is one on the 50cc scooter's wiring system. I'll hafta look into that. Thanks! Regulator/rectifier is just what it says, it regulates the ac voltage fron stator down to around 14-16vac, then rectifies it into DC power. Regular incandescent bulbs can use either AC or DC power, as long as the voltage is close. To much voltage and the element heats up to much and blows. The r/r is what keeps this from happening, also keeps from frying your battery by applying dc voltage to it instead of ac... |

I've been told that if the the headlight glows as soon as you turn on the key, its a DC system. If it doesn't light up until the engine is running, you have an AC system. True. Get a higher wattage bulbs(55w for 150cc i beleve), if those blow, replace regulator/rectifier. |

Subject says it all. Anyone know of a good quality usa made kevlar belt for 50cc scoots?
I prefer usa made, but anything better than the china belts and name-brand knockoffs on ebay will work.

Didin't know 83 octane even exist today, here in Sweden it's only  and and on my scooter the manual says to use octane but i have no choice but We have all sorts of diluted but pricey fuel here in the US... Kind of ridiculous when you think about it. Who in their right mind would intentionally feed their engine ethanol-diluted fuel? |

Super Hornet 150cc . . Compression Ratio 9.20:1 . . low-octane gas should be sufficient. High-octane gas is actually diluted (slightly less energy) to delay ignition in high compression engines. True. In my bikes, or any small engines for that matter, I always run ethanol-free or "marine" gas. The carb issues we so frequently experience such as varnish/gumming up can usually be avoided by not using gas with ethanol. This gas usually has an octain rating around . I have had zero problems running this, even on a custom machined 80cc bbk piston/head i did for a "high" compression setup i had a few years back. |

Check clutch springs, weak or broke clutch springs will cause this also as the arm will prrmaturely engage the bell, putting load on motor. |

jet also.
