 Posted: 14:56 - 01 Sep 2007  Post subject: Baotian is basically just not working right |
 |
|
For the last few trips out, while I've been pulling out of the driveway, my Baotian doesn't seem to be revving up as it should. I twist the throttle a good 50%-60%, then sit and wait a second or two before the thing revs up and moves off. I can't say I notice it when I'm out on the road at junctions etc., it seems to run fine after a little while... unless I'm just not paying attention. Is it simply a case of me not warming it up properly/for long enough? 
FYI, it's a 4 stroke 50cc Chinese scooter, almost new (a month in my possession from new), 475km on the clock. 
Also, while I'm here, my front wheel is a bit squeaky. What do I do with that? 
EDIT: Forgot to mention, it also seems to be taking longer to reach 40mph than it did 100-200km ago.

The lil' monkey does this and can be quite entertaining at times.
When warm no problems at all.
When cold and trying to warm up different kettle of fish . The bike will start and turn over on the first push of the button. The revs are low (summer and no choke), the slightest twist of the wrist and the bike cuts out. Start again, again low revs, again cuts out when the throttle is opened.
Or
When the throttle is opened it splutters a little and then after a short pause the revs pick up albeit a little boggy in its response.
The warmer the engine the less this happens.
Its a pain in the ass having to sit there for 5 minutes or so, especially when you have to start from scratch if the bike has been left for 30-45 minutes.
If I try and ride the bike before all this foreplay has been carried out the bike just cuts out when the clutch is let out to pull away. If however the bike allows enough revs for the bike to pull away the ride is a little ropey with either too little or too many revs.
The number of times I have been at the 1st or second junction waiting to turn, blipping the revs to try and warm the air cooled single cylinder and gone to pull away and the revs have died leaving me stranded in the middle of the road, with the right hand yanking hard on the bars, all of a sudden huge revs, front wheel at an angle and an uncontrollable wheelie from the junction in front of the up and coming cars  . Frank Spencer eat your heart out.
I've often wondered if it was something wrong with the carbs or fuelling to be honest but been to bone idle to worry, as said its a hioney once warm.

I read the little workshop manual when I unpacked the beast from its crate last December and thought 'sod that'. I now that you are supposed to break an engine in gently and try to minimise harsh acceleration and prolonged periods of speed, but....when the top speed is around 50mph tops, I am not riding for the 1st few hundred miles at 20 odd!
The bike has been caned to an inch of its life so far and its still ticking and looking after me even if I'm not looking after it.
Ride and enjoy! Just take your time before setting of

Hey, thanks for all your input guys, much appreciated. 
I actually got round to having a look at it just now after having some hideous experiences this week on my way to/from college.
First thing I did was open the air filter box and check the element. Took it out, and there was a bit of oil in there. I looked around the other side and took the dipstick out... the oil level was right at the top! 
It had it's first service two Mondays ago and I was told 'You'll probably need to top it up when you get home', and given the remains of a litre-bottle of oil that was freshly opened for the oil change. I took the scenic route back home and once got there, checked the oil level. There was barely any on the dipstick so I put what was left in the bottle in bit by bit, checking every time. I checked again after emptying the bottle and the oil was about half way between min and max marks. I haven't checked since, until today where it was ridiculously high.
Anyway, I've siphoned a bit out and got it to a sensible level. I'm gonna wait until rush hour is over before I take it out for a spin. Could this be what caused the reduced engine power?

Ok thanks lukamon, I'll look into it.
Been and took it out about 8pm while the sun was starting to set.
Went out with low beams on, had the usual crap trying to get out of the driveway (no revs), got flashed by a few people, got home, lights weren't on any more. Checked high beams, they worked, checked side lights, they didn't work, checked low beams again, they didn't work. Turned ignition off and wheeled it into yard, got on it, turned alarm back off (FYI the alarm comes on automatically after turning ignition off), turned key (I wanted to check the lights again), was just about to press electric start when the fuel gauge went dead. Turned ignition off and back on, kaput. Pressed alarm several times, tried allsorts of stuff and nothing happened. Checked fuse, it had blown, replaced it with spare, went through starting process again, didn't work again. Checked fuse, that had gone too.
So what the hell is going on? I've heard about power surges and such, but what causes them? Could this be what it is? If so, why didn't the lights work on low beam/side lights? FYI the original fuse also blew after about a week of me getting it brand new (about a month ago). Is it just a poor build or what?
It's under warranty so I think I'll get in touch with the garage next week.
