hey gang,gotta question for ya..I changed my oil at 600 miles and the oil smelled heavy with gas,I just attributed to the break in process..during routine maint. I checked the oil(1200 miles) it was black and wreaked of gas..I suspect a broken ring or a cracked piston..has anybody had the same problem??

Everytime I change my oil it has been thinner than when I put the oil in.
I haven't noticed a gaseous smell though.

Have you changed your scoot at all  If your scoot has been modified it could be running rich. If the airfilter has gotten wet it would do the same. The paper swells and the filter won't breath. It could be normal if you run a heavy load or at full throttle all the time  |

ahem, f...fu....fu...ful...full throttle all the time? No, not me  The only way I drive it usually is at full throttle or no throttle haha. |

I guess that was a dumb question  Do you run at full throttle down hill or with a heavy load? Your carb could be on the fritz |

hmm, 3200 miles... Almost the entire time on full throttle... I carry a passenger quite often. I bend down and gun it down every single hill! I've hit 43mph baby ya! The ruckus is so damn slow |

And once I pulled a 1960's cushman cart (like they use to carry bags at the airport too and from planes) about 2 miles across town with a heavy chain very slowly because it broke down haha. It was a friend of mine's that broke down and his dad was out of town for the weekend so he couldn't tow it home. grrrrrrrrrrrrrrrrrrrrr super-high revs @ 5mph That' couldn't of been too good for it either right? My Ruckus only does 36 on flat nowadays when it did 39-40 when I got it. I only weigh 125 pounds. |

So,what you are telling me is..if I lost 100 or 125 pounds and slowed down a bit the problem should go away on it's own...GREAT!!

It may not seem that way at times but it's my goal ;D If the gas in oil seems like more than your use to I would take it to the dealer. Is it getting good MPG The Ruckus was designed for little Japanese girls and or people up to 200lbs so if you are going over that it could be a factor. You never know. |

Hey,Abe..I'm joking!! it's cool..mine's dead stock..gets damn near 90 mpg...gets up to 37 mph,with me on it(250#~260# depending on what I had for lunch)it'll do 40 down hill,rolling back on the throttle..I'll just have to change oil more often,I'm afraid the gas may wash the bearings out of it..

It's a small engine that revs to the moon. With my Hondas I always change the oil at half the mileage they say. Better safe than sorry  |

Just registered and was browsing around and saw this thread. I had the same problem with about 200 miles on the clock. Under warranty, I took it to the dealer who said it was likely a sticking enricher (auto choke of sorts)and that excess fuel could leak into the cylinder and past the rings into the crankcase. They checked the enricher and said it worked fine and might have been a one time problem. I ride in the winter and use Stabil too, so I don't think it was gummy gas. When I first changed the oil it smelled strongly of gas and the oil had a greenish tinge. They said the gas smell would eventually dissipate, which it seems to be doing but I'm keeping an eye on it. The only other symptom that might be related was that hard on the throttle it would bog down (recognizing its got a piston the diameter of a half-dollar) and then work its way up to speed. That sympton seems to be gone now (recognizing its got a piston...) . |

Sorry to revive this thread, but I had to chime in because I have had the same problem and want to avoid having it again.
I have a 2003 bought at season's end last year, so I only put about 100 miles on it before I had to stow it away for winter. Once Spring rolled around, I used it quite a bit. As the summer of 2004 poured on, I noticed that it was getting progressively slower at taking longer to get up and go--even to that slower speed.
I figured that it might have been bad gas or water in the gas (from condensation) and added a little octane booster and a touch of gas-line antifreeze. It didn't help, so I finally just brought it in.
They told me that the air filter was fine, but the air tube was pretty clogged up and so gas got into the oil and caused that sluggish performance. After a carb cleaning and oil change, it ran much better, but even now I still notice that when I first start it up after sitting for half a day, it sputters a little bit. Once it is running, for a few minutes (or half a mile at full throttle), it is OK. I am around 600 total miles right now.
So my question: Is this the beginning of this problem starting over again, and do I need to do anything special to this thing when I stow it over the winter months?

It's just hard to know without looking at the scoots.
One of the things with the Ruckus is the drive can keep the
motor in too tall of a ratio. The rollers are a little heavy
and it can bogg the motor. If you are giving full throttle
and it's not moving (at times) you can flood the motor.
Are you seeing anything like that?

I've been taking it to work everyday for a while now. For me work is about a mile and a half away and using the Ruckus is adding years of life to my Buick. I will continue to scoot until the snow actually sticks to the ground and they're predicting a late start to winter, so maybe I get through to Christmas. The problem is that the cold here is still a "wet" cold. So when I leave in the morning, I pretty much start it up and take off. Should I let it warm up at all?
Here's what happens when I take off right away: As I accelerate, I usually put it up full-throttle. As it goes, it revs high and then sputters. Since I used to drive a '77 Chevy Caprice, I'm not unfamiliar with this behavior, so when that happens, I immediately leave off the throttle and then crank it back while I am riding (sometimes once or twice) until it catches again.
Again, after about 2 minutes of riding, the problem goes away so I figure it might just be condensation working itself out. However, I don't know enough about the four-stroke engine to make that statement confidently. It could just as easily be the precursor to that gas in the oil or plugged carburetor that I had last Spring.
I always use the high octane fuel, but do you think I should add a cleaner or anything to that?

Every so often take your scoot out for a good, fun leisurely drive. Get the engine up to temp and run it until the moisture is evaporated. You might want to switch to a lower octane fuel also. I run the medium grade fuel personally. I used to drive a really old pick-up that required a friend's finger in the carb to get it started and I never had a sputter problem with it cold. So, I have to admit I'm not sure what that means. With my experience driving diesels though, cold engines make for a poor running engine in the morning. You may be running into an issue of the fuel not combusting as well as it should since the higher octane means that it won't combust at lower temps (useful in higher compression engines since pressure=heat) I'm pulling at straws here, but with a lower block temperature combustion may be impeded. Lower octane implies lower temp combustion. Just a thought, save some money and maybe stop sputtering. I hope ppl feel free to chime in and spank my take on this. ;D

Well, this morning wasn't too cold (36? F) and the air actually felt dry, but all the same, I decided to let the engine run a little before I took off. So it sat idling for about six minutes before I hopped on. When I did finally go, it ran perfectly. So... my thoughts on condensation? Right? Wrong? Also, your thoughts on gas are interesting. I just assumed that higher was better and cleaner. I always put low-grade in the Buick, but I figured that higher in the Ruckus would help with stray particles in the tank and such. |

Premium is really not worth the cost unless you run a ultra-performance vehicle. The ruckus manual says to use 86 or higher octane. I like 89 in mine.

The stumbling is the result of the electric automatic choke.
Sort of like the old automotive manual choke. Runs better
as it warms up. I have experienced the same thing, so I
make sure that my Ruck runs for 5 or 6 minutes in the garage
before I take it outside. The cooler the weather the longer
it will take the choke to be wide open. Even in warm weather, I always made sure to let it run for a few minutes
before I got on & hammered it. Have fun. Ride safe.
