My Scooter Is Acting Up Again And I Dont Know WHy... IT Happened before.... it just runs really slow like it isnt giving any power....it cuts in and out ... it goes like 25 when i should be going 35 mph...when it did it before i checked the air filter and there was all this gunky gas smellin stuff i drained it out and it seemed to run better... i have 4400 miles on it ... ive changed the oil twice and changed the spark plug once already....there was some black stuff in my airfilter this time i got it out and i thought it would run better but it didnt help...let me know if u guys know what else it could be....o yea what are rollers?

You gotta be more specific on "what are rollers"

My guess is you overfilled the oil at the last oil change. What kind of scooter?

Scooters usually have CVTs instead of "proper" transmissions.

Rollers are a part of most of those tiny CVTs.

umm lets see... this morning my scooter wouldn't even go anywhere its just seems like it isnt getting gas... im taking the thing all apart looking at everything possible... there isnt too much oil in it for sure... maybe to little...my dad read some forum about how my prob could have to do with rollers so thats why i wanted to know what that was about...its a metropolitan 2006...

ok ..update... we are starting to think the fuel is to rich it is getting more gas then air and flooding itself... so that means carburator .... my dad takes these 2 hoses of the carburator and this radiator fluid lookin smeillin stuff is coming out of it.... is that supposed to happen? thats all for now.... please help me out some more

It Was The Coolant Going Through The Vacum Tubes ...That Isnt Normal my Dad Says...we took those tubes off the carb and it drained all my coolant out...

It sounds like your scooter has 'heated' carb, common on snowmobiles here, but probably to cool the carb if it sits in the dark, hot cavity I imagine it is in on most scooters. If those were vacuum lines, and they were somehow wrongly connected to the cooling system, the engine would suck so much coolant in it wouldn't run. Not for more than a few seconds. So those coolant lines must be there from factory.

Sounds like you could use a good shop manual for your scooter. It will describe all these things, and show pictures, for your machine. They really are the best tool for any bike, for every person who works on it too.

If your scoot uses a belt in the CVT and not a chain, a worn/burnt belt can act like the way you describe your scooter. So can bad rollers in the CVT. I wouldn't advise tearing apart your CVT clutch without a manual. It will contain some pretty powerful spring pressure that can hurt you if done wrong.
