Got 750 miles on the new 250S and it has developed an annoying problem, not serious, just enough to gripe my ass: when I hit speed bumps or other slight protrusions like a small curb into the drive way or small pot holes where tire drops down in, it has a rattle from somewhere in the dash board-instrument panel. I have tightened every screw-bolt i can find and it still does it. Any ideas  not a metalic sound but rather a plastic on plastic sound. maybe something behind the cluster. anyone else have this |

Also, there were some threads I can't find on the 250 engine noise. I thought for sure it was valve rattle. an adjustment and a switch to 89 octane gas made some improvement but it is still noisier than a honda 250 and alot quiter than a burgman 400 but it also concerns me. the dealer mechanic says they are all like this. It's kind of an exhaust crackel he says and not from the engine but from the port. can't prove it by me. so far I have just ignored it and enjoyed the ride. anyone else have this issue ? |

I'd lean on the dealer on the rattle from the dash. Try 91 octane & see if your tap goes away. If it doesn't, I'd lean a little more on the dealer. The Xciting 250 doesn't have this noise and I assume it's the same engine. Typical mechanic's response for something they don't want to mess with..."Oh, that's typical". Crackle from the port? What the hell does that mean? Or, could it be that you are just a totally paranoid guy about every little noise your scooter makes? No, I'm guessing that you are just a man who is one with his machine, feeling and sensing all. Go forth and conquer. ;D Hey, tell them that you would expect the dash rattle from a cheap Chinese scooter but you paid extra for a Kymco. That should "rattle" 'em.

could the noise be from this huge monster windshield I put on the thing?? It rises 2 inches over my head and I'm 6ft-1 inch. I mean it's huge. unhandy as hell when it fogs over. have to look out around it. maybe I will take it off and test ride it without. maybe after the engine wears in a little more and higher test gas, it will self correct. compression is 10.6 to 1 and the book says 92 to 95 octane is best. what do you think dealer said 87 was OK and I don't buy it. |

my wife says I'm paranoid as hell. every time I hear something, I'm lookin for it and trying to fix it cause it just ain't right. she on the other hand wouldn't recognize engine lock up or a missing tire. her response would be: well that's the way it's supposed to be I guess so I just kept going.

My Kymco also makes a really weird gurgling exhaust sound, but it was obvious to me it was the exhaust. I really don't like the way it sounds but my Kymco dealer said it was a Kymco sound, so I have to live with it. One good thing is you can really tell when you crank it up a bit.
I think you and I are talking about the same sound and it doesn't sound like other scooters but if both of our dealers says it is normal, I guess it is?

Also, stupid question, but what type of key ring do you have on your scooter key? I know, it's a dumb question but I was riding and hit a bump and heard a rattle, plastic on plastic. It got my attention until I realized the key fob for my wife's HHR was hitting the leg shield.

Any bike with compression of 10:1 or greater recommends that you use 91 octane. Only the lower compression cruisers such as the V*s can get away with regular, and in fact 91 degrades their performance.

I'll try the 91. can't find 95 anywhere. did find 93 from shell but I hate shell gas. never was any good in my opinion.

my key fob is a beer can but it's not metallic remember.
also, after reaching altitude and you start cruizin, the sound goes away. only under throttle does it make this wierd sound. the engine is not the same as the other 250 kymco's. so they say.

speaking of my wife, I came home from work one day and saw the garden tractor out in the middle of the field. A note on the kitchen table: something wrong with the tractor. had to go shopping. changed the oil and it just quit out there. upon inspection, no oil on the dip stick. also, no oil plug in the engine. big puddle of oil in the drive way with an oil plug in the middle of it. duh, I forgot to put the plug back in i guess. It just quit out there. 22 HP Sears engine gone. well, what the hell, she tried to help, AGAIN. ------------------------------------------ also changed the tire on my pickup one day. next morning the tire was flat. Looking at it I saw a plastic screwdriver handle sticking out of the tire. I wondered where that went she said. It appears that to keep the tire from turning when tightening the lugs, rather than letting the tire down against the ground, she jammed the screwdriver against the tire and the ground. When done, she let the jack down and presto, screwdriver in tire syndrome. ------------------------------- also, came home from work one day and saw 4 pieces of barn siding off on the ground. It appears when backing the tractor out with the snow plow on it, she turned while looking back and presto, she ripped the side of the barn off. should I go on ? could she stay at your place for awhile??? she's a big help around the house. |

Twister, we arent talking about the same exhaust sound, then. Mine is when you give it a good bit of throttle, it has a strange exhaust note. About your wife, that's some funny stuff. I'll pass on the offer, though, thanks  And have a karma back on me, seems someone likes to take mine, too. |

Have you taken the dashboard apart? I'll toss out a possibility you probably haven't considered. On my Kymco Vitality the turn signal winker is held by a rubber bracket, one side is the hole that the winker fits through, the other has a slot that goes over a tab on the front of the dashboard, so yours might've come loose (mine broke off).

took the windshield off this afternoon. nary a peep of a rattle without it. put it back on and test rode it and the rattle is back. can't figure where it comes from. will keep looking though. gives me a purpose.

Twister;
Could be that tall windshield is placing a lot of stress on the front end panels when it catches the wind at speed. Possible for it to cause some parts to give some under the stress and make the noise.

Also check for loose fasteners on the parts that the windshield fastens to. I ran into this on my Burgman.

QUIET AS A MOUSE:
I remounted the touring screen. I decided that since all of the 7 mounts were what I call hard mounted, the wind vibration and pot hole bounce caused the fairing to rattle. I remounted the entire screen on soft mount rubber bushings. Also, the instructions called to use the steel bushings in the rubber mounts at the bottom leading edge of the screen. I removed the bushings. Now all of the vibration is taken up by 7 rubber bushings. Presto, no more fairing rattle.
Ain't I creative and wonderful.
You can't tighten the screws down as tight as before or you smash the rubber bushings and they will be as hard as the hard mount. Put loktite on all the screws and tighten down to just a snug fit and wait for it to set up.

I thought I was the only one having a week that things went stupid. Twister you are not alone with the week from hell. It's the curse of the "Backside of a full Moon" again. It's going to get better, I think, maybe, s!!t I don't know. Good luck in your quest for the quiet scoot.

Howdy Twister! I've got the small windscreen and have had to "Adjust" here and there, but it has the rubber bushings. I check the body panel screws every week, the underseat box every week, and the exhaust fasteners every week as well. I had a similar problem with my engine...a weird clattering noise that would pop up during wide throttle openings that turned out to be a worn crank journal...I agree with Lee..."Exhaust Crackle" !!! I think the mechanic has been smoking some exhaust crackle to come up with an excuse like that. If he's talking about popping and crackling, then it would be a leak somewhere, maybe a loose fastener on the can or where the pipe attaches to the port... The dash rattle leaves me clueless...maybe the mechanic should open it up and have a look-see. Have a Karma on me! John |

Dash Rattle comes from the plastic cover over the instruments. It is attached to the instrument box under the fairing. the whole assembly is then pushed up through the fairing cut out. This is where the rattle comes from. the plastic cover against the fairing cutout. needs a rubber seal around the cluster and the fairing.
my fix, clamped the dam thing down against the fairing.
engine noise somewhat reduced. mostly at full throttle now. back off on that and noise subsides. sounds like a blender chopping ice cubes.

MORE INVESTIGATION:
After some complaining to the dealer on engine noise, he claimed my problem is not with the engine but with the variator. My answere was OK, sure, if you say so.
Gave it some thought and put the thing on the center stand and had the wife run it up to 45MPH. I looked for the noise source. Guess what. It's the dam variator rollers like he said. Engine is quiet. The noise from off the scooter isn't as bad as I thought. On the scooter it is much louder and the dealer told me it was the windshield that amplifies the sound back to the rider. Without the big screen, it's not a factor with other owners. All of us with the touring screen have called and complained.
Kymco has no options at this time to quiet it down. It's one of those live with it deals. If that's the worst of it, this scoot is still one fine scoot and I'm happy with it.

got 1700 miles on the new people S250 now. changed the oil myself-synthetic mobile 1. hope it's a good choice.
Have to tell you, if you just have to have a quality scooter that looks like a MC and rides like a caddy, this is the one. It is just one fine scooter. will run easily over 75 MPH and gets 72 MPG so far. goes 65 MPH all day with no strain. 2/3 throttle, no more.
