The noise persists whether I'm at idle or revving, but as the revs increase the noise becomes faster. No wobble in my crankshaft that I can discern. Unfortunately my impact is too weak to get the variator off for me to inspect. So while I wait for a better one or find a tool to remove it with, does anyone have any suggestions as to what this hellish noise could be? I'm hoping it's just a loose roller guide or worn roller (these are the stock variator and rollers after all and I'm at 6000km). I've had the cover off and nothing looks out of the ordinary. Scooter rides just fine, no problems in that department...but I am terrified it may just blow up or seize the rear wheel on me. It sounds loudest by the variator, but when I used the old screwdriver to the ear trick it sounded like it was coming from inside the starter motor. Does this make any sense? I'm so frustrated with this. Help!!  |

You can use a big screwdriver and hold the variator in place as you try to beak it loose. Just be carefull you can damage the variator fans this way. Hope that helps. I have no audio on my computer so i cant help with the noise.

To me it almost sounds like it could be bearings going on the crank, have you checked your oil, and if so did you have any shiny bits on the dipstick? But in case it is in the CVT, remove the CVT cover and see if when you run it if you can tell where it is coming from. Also have you checked the valves to make sure they are not loose and causing the noise. I may be totally off and hope it is an easy fix for you, just throwing out some ideas.

No shiny metal in my oil keikara , I just recently changed my oil, gear oil and drive belt within the last 500km. If it is coming from anywhere in my CVT it's absolutely the variator area, which makes me scared for my crankshaft. |

If it is coming from anywhere in my CVT it's absolutely the variator area, which makes me scared for my crankshaft. Go for a 30min ride, then quickly pull the cvt cover and try again with the impact on the variator... if rusted on use a quality penetrating oil one spray every two hours, between sprays on the off hours try to impact it off. Didnt watch the vid but my hoca variator made my CVT noticiably louder due to the fan being different. Got even louder after the chromed/vented cover was installed. Edit:After watching the vid it definatly sounds like something imbalanced in either the cvt or clutch. If you can get the belt off run it without the belt and see if it sounds the same. This rules out the clutch. If you get the same noise then check the variator and the flywheel. If nothing is amiss on either end there then i regret to inform you that you will be splitting your case and inspecting the crank itself. |

Ive read a strap wrench works great to hold the variator so you can just loosen it with a socket and breaker bar. No chance of breaking any fins that way. They only cost like 15 bucks and it should work for the clutch too

Thanks for the tip. ive been using a screwdriver if i never had an impact. |

I'll see what I can do about getting it off tomorrow most likely. Shame since I was really looking forward to scooting down to the shore for 4th of July fireworks. It's going to be a real bummer to have to split that case though lol. I'm fairly certain I'm just delaying the inevitable.

Proof that our collective knowledge can solve just about any problem on these bikes. |

Sounds just like a customers Scoot when his crank bearings went. We could not wobble or move the crank..but when we ran it wit CVT cover off..we could see the variator wobble and make lots of noise. Remove CVT cover.. If it is a 4 stroke hold a small socket on the end of the starter bendix (so it won't pop out when you crank it) If it is a 2 stroke just remove the cover and start it. Look for wobble in the variator. If present ..the variator is WAY out of balance..but each time I have seen the wobble..the crank bearings were shot..  |
