Rattling noise from my Baotian

[GDOBSSOR]

Bought a 50cc baotian almost six months ago. No incident up til now (has about 4600 ks on the clock btw and has been serviced about every 1500 ks).

Sept 21st - was coming home from work and heard rattling noise coming from engine when I tried to push scooter above 40 and also noticed an occasional burning smell. I asked my mechanically minded friend about it. He checked air filter, fuel gage and looked at exhaust (although he couldn't check exhaust thoroughly). He saw a hose that seemed to be disconnected but he couldn't see what it was discoonected from.

I took it to Scooterazzi as it was reccommended by said friend who is an experienced motorcyclist. They said they'd have a look. Monday - get a call. "Nothing wrong with it." Tuesday, they find that it's running lean so they correct that and let me take it home.

Saturday, I am on my way to a friend's house when the engine starts making an incredibly rough grinding noise and won't go above 30kph at all. When I pull over, engine cuts out. I wheel it to my friend's house which was fortunately down the road.

When I got it home, it took Dad about eight tries to start it. This has never happened before. When it finally started, it made an incredibly rough idling noise, and when he revved the engine, it made an incredibly rough grinding noise. When he took his hand off the throttle, the engine cut out.

When we got it back to Scooterazzi the next Tuesday, I described all this to them and told them that I was too afraid to ride it or let anyone else ride it, and to make sure it was in good working order before giving it back. They gave it back the following Thursday at a cost of $300, having replaced the drive belt and clutch and sheaves. It started okay, but vibrated when idling.

The following day, on my way to work, it started making the rattling noise AGAIN, after I had spent $300 on getting rid of the problem. I managed to get home in one piece, but it now makes a loud rattling noise if I accelerate, decelerate or ride above 40kph.

I am a student and I don't have a lot of money. I rely on that scooter to get to work and lectures. At the moment, I'm afraid to ride it for fear it could break down completely on me again. I personally don't find this acceptable after having spent $300 and explicitly telling them I wanted the scooter in working order so I could have people test ride it (I want to sell it to get a motorbike).

Any idea as to what the hell this problem could be and any idea as to what my rights are?

is it a two stroke or a four stroke?

[FJRider]

Get your mum to start it ... I always got my mum to start mine ...




It's probably fucked though ... I'll give ya $5.00 for it. (Delivered)

[p.dath]

I'll take a guess it had more than one problem, and your $300 in vestment has solved the first bunch of problems, and now you are onto the next problem.

Does the problem only happen when the motor is warm?

Less than 6 months old, and less than 5000km. Surely it still has a new vehicle warranty. Get the dealer to fix it for free.

I had to google them ... I've never heard of them.

Being a chinese made scooter I'm surprised you found anybody willing to work on it.

Your initial description made me think serious engine problems like crank bearings. My Italian made Yamaha scooter had a vaguely similar sounding fault, twice. Turned out to be the big end had chewed the hardening off the pin. If you are riding it hard, which on this 2.6Kw scooter would be trying to do 50kmh, unless it's been made with quality parts you can expect problems I think.

Sorry I can't think of anything quick to check. A very careful look at the oil under a strong light would be a good idea. Pull the dipstick out and look for any sparkles in the oil. Sparkles will be bearing material which is not good.

4500 km's at (or near) max speed can't be good for a 50cc engine ... I'm still going with "It's fucked" ... and the $5.00 offer still stands. (delivered)

The problem you have is, as has been mentioned, they're not of very good quality. Mark and his workers at the Scooter joint were brave even looking at it for you. They may well have fixed one issue, only for it to have several more (also as mentioned). It does sound like a crank type issue, and it won't be worth fixing if it's not covered by some type of warranty. Buy one of the known brands next time, and you'll be sweet.

Perhaps ... comments like that wont make you friends at the scooter place.

Were the reasons you bought it ... ???????

1. It was cheap.

2. It was new ... and cheap.

3. You looked at other scooters ... but that one was cheaper.

These little chinese scooters use a copy of a Honda motor. Quality varies widely, but generally isn't very good.

You may have a claim if you got the bike from a dealer, but if privately purchased or from TradeMe, you don't really have any comeback.

Scooterrazzi surprised me by even looking at at. When I had "Scooters Plus" we soon learned the hard way that no matter what you spend on those little chinese scooters they will haunt you, so we soon stopped touching them.

NZ has a wide range of good quality scooters available, and they are seldom much more than the cheap chinese ones. We sold Peugeot and TGB, and I can say we had a good run from both. My own TGB has now done > 45000 km with only a set of rings, and thats an hours work.

Most of the Taiwanese bikes will do these kinds of mileages, and the jappas are all very good as well. The Honda Today is chinese, but Honda keep an eye on the manufacturing, and I have not heard of any premature failures on them, and they are only $2k brand new.

Rather than continuing to throw money at your cheap scooter, it may be time to look at a better quality bike.

Yes the problem only happens when the motor is warm. I don't think I can just take it back to the shop as it is actually 18 months old (I am second owner). I would if I could. It is ok when it idles. Thing is, I know people who have bought Chinese scooters and they've had problems with them from day one. This is the first real issue it's had in 4500 ks of motoring so I'd still like to see if something can be done. I admit I probably was a bit quick to attack Scooterazzi.

Good girl. Mark's a decent chap.

I don't really want to make any enemies... Thing is, the last two weeks have been incredibly stressful. Without my vehicle, I can't function properly. Hence the language.

I bet. Being without wheels sucks serious arse. I'll keep my eye out for a good scooter for you. I work for Wellington Motorcycles and sometimes get some cheap but goodins traded in. I personally sold a very good Honda DJ1 for $800.00 a few weeks back. Looked after it'll last for years.
