Hey are the 250 lifan engines any good. Cuz i was thinkin about getting 1 soon
any feedback would be great!!!

HI FOX DUDE 77.

Tell your friend (cuzi) to stop thinkin and go get im one. I hear tell dem thare 250's are slicker than a watermellin seed! Ya all git a cruzy too, an go a runnin whit dem big dawgs!

leev dem dam 200 sportys too da yung pups.

Gotta run, da grits r boilin over.

Seriously, I hear they are excellent motors, and others should agree.

i have a brand new lf200 with about 120 miles on it i cant keep the bike running at idle when its cold and the choke seems to do nothing to help it idle i end up killing the battery before i can keep it running and i already set the idle at 1500rpms when it was warm like the book said just another note this thing is the hardest kick starting bike ive ever seen i can jump on it and it still wont start please help me

HI. If the choke seems to do nothing than it needs to be adjusted at the clamp on the carb. Most likely it's not closing enough to create sufficient  vacuum for an adequate fuel flow at starting.

If the motors starts and then stalls out after a few seconds than it could also need the the idle (slow circuit) richened by turning in  the air bleed screw at the front of the carb.

Try to raise the idle speed using the chrome screw on the side of the carb when adjusting the brass air bleed screw. when the weather was cold to aide in starting I had my idle speed at 1600 to 1700 RPM according to the factory installed tachometer.

Always write down any adjustments you make (air screw in 1 turn, for example) so you can maintain a point of reference and return.

What is that clattering noise when starting up, sometimes loud and sometimes not at all? Is that a problem? Can it be quieted down?

The noises you are hearing are normal. there is quite a bit of clearance in the starter gear cluster and other connecting parts, and what your hearing is the slap and backlash of the gears, connecting rod, piston, and other internal parts. I understand your concerns, these sounds (clunks) can be very loud at times but rest assured that these  are present in this type of motor.

I have taken apart  my Lifan 200 motor (loud clunker) on two occasions and all is well.

With every on-line seller there are happy stories and sad stories. This is the nature of buying on line.

I think that buying from an established seller with a retail store is the best bet since a  2 to 3 hundred dollar savings won't matter when you get stuck by a seller that won't honor their warranty. You wouldn't pay up front and pick up a damaged bike would you? Well online sellers can show a web page full of parts, and that doesn't mean that they have them in stock when needed, or at all for that matter.
Many of these sellers don't have possession of the products they sell and will never admit it. I have seen sellers take a customers money for a bike and when its received they find out it was bought from another seller or maybe an importer warehouse. All of these guys have some really good and believable excuses when you catch on and start asking questions like why is my bike a different brand then what I ordered? Why are my parts the wrong brand or color when you continually display the correct parts as being available?
Online sellers have an interesting warranty that read carefully actually tell whats NOT covered. And after you read it you will realize that almost nothing is covered by their warranty!
The idea is to make you think you have a good warranty and the clever way its presented instills consumer confidence. A classic example is the 3YEAR WARRANTY! This is absolutely the most  ridiculous claim to date! Just ask a real biker, or bike shop.
 Before buying a bike try to order 3-4 silly little inexpensive parts (a bulb, a foot peg pad, a dip stick gasket, and a spring for the foot brake) to see how good their service really is, make sure they are wear parts that are specific to the bike you are thinking of ordering, this way they can be used or sold later.

Edit; My contact at Rocketa that I buy parts through said that "Kung Foo" sales have been dead flat due to price and their "Fugly look". It was never told that its been discontinued by either the manufacturer or Rocketa. Usually Rocketa  runs a closeout (discontinued) sale to dealers. This usually generates sales to help liquidate stock on models they want to clear out. As far as I know Rocketa doesn't sell to the public.
Please remember, the description "Fugly" was not mine. I think its kinda nice, but a slightly unusual looking bike.

Hi guys, recently bought a 125 J from my uncle who has had it from new since December, he used it to learn on...

When I rode the machine yestederday for the first time, it feels as though the rear end shifts, wobbles every time you open throttle slightly or change gear..?/

Any idea's?

David in the UK

HI guy. I would get the back end  up off the ground and check for a loose wheel bearing or loose swing arm bearing. Its most likely that one or the other is the culprit, if not both.

When you say "shifts" I assume you mean side to side?

Edit: Another possibility is that the rubber cushions between the  sprocket carrier and the wheel hub may be worn out.

Check it out and let us know what you find.

Hi.I just back from 6 hours of some intense driving which has left me pretty well whipped, so I'll be brief.

The problem could have a lot of answers and is very difficult to address. Think of it this way, you call your doctor because you have abdominal pain, and want to know what you should do to fix the problem.
Do you see what I mean? But I'll try to help, please bear in mind that I have limited knowledge in this area of diagnostics.

The most likely cause of your problem is procedural.

Lets assume you just got back from a ride or ran your motor.

Step 1) Engine run switch (red) is snapped to OFF.

Step 2) Ignition switch (key) must be turned to OFF.

Failure to follow these 2 steps will allow the battery to drain. This type of drain is a well known problem with Jet ski CDI ignitions that circulate power (using their "brain") to maintain a charged capacitor. And if the green neutral light is on it will also drain you battery.

The only indication of the ignition switch (key) being left on accidentally is the neutral (green) light. This light is very dim and seeing it in daylight can be a bit of a problem. This problem is compounded by the fact that it's very common for many to leave the bike in neutral, this is most likely due it being the only gear position that will allow the starter to engage.

This of course leads me to mention another potential procedural problem, of not locking the bike's ability to roll while it's parked. Leaving it in first gear is a necessary step since there is no PARK option, or brake LOCK on either the foot or hand brake. Remember that the first gear indicator is a bit more visible than the green neutral light.

I do not mean this post to be a "lecture," it's purpose is to help with understanding a possible cause of your problem, and to help you to avoid another potential one.

 Thanks. Buyingchina

I'm not even sure if the GRX is part of the model name.  I am talking about the 250cc lifan sport bike that looks like a bmw.  I have also heard it called the kung fu on the rabbit motor scooters site.

basically i want to know...   if speed and performance are your thing, is it worth it to spend the nearly 1000 more to get an extra 50cc (and and extra cyclinder)?


what are the pros and cons of the lifan grx 200cc vs the 250cc?

also have some questions about the 200cc  - the guy i am planning on buying from  motorcycles-wholesale.com) says that the bike is a OHV (push-rod) i have read that there are OHC versions, he says that they do not make them that way anymore, is that true?

Does anyone know anything good or bad about Motorcycles Wholesale or Gordon Whittet the owner?

can you pull a wheelie on either the 200cc or the 250cc?

I am a first time bike buyer and on or the other of these seems like my best bet. 

if anyone has any suggestions on places to gather some unbiased info on either of these cycles i would appreciate it, thanks for your time.

If speed and performance are your thing the difference between a China 200cc vs 250cc is not note worthy.

Heres a link to info about the dealer you mentioned:  http://www.ripoffreport.com/reports/0/293/ripoff0293236.htm

Unbiased info: spend some time doing research on any bike or dealer you choose. There might be a little bit of bias out there, I think. Your best bet is the old saying "cash and carry" , you see it, you like it. you buy it. Any cost saving idea's can go belly up, I know this first hand.

Hi. I don't know of any one that ever bought that (kung- fu)  bike, but I think its been on a dead list of unsold bikes at Rocketa for quite a while. Could be a bike thats drop shipped by them for any one lucky enough to snag a buyer! If you can find out the model year that should tell you the story.

Edit: I just took a look and the pictures look like a copy/ paste job. That's a good way to do it if you don't have possession of the bike. The question would be, who actually owns the bike? And who has parts? Wheelies? I did those on a 10 speed bike before I ever had a motorcycle, but that's a distant memory of my younger past. Maybe some one will come forward with that info using a 200cc sport bike, like the LF 200-iii. Any volunteers?


Thanks. Buyingchina

Again a small problem when I hit my brakes the light does not come on usually they blink during your braking period... I just installed a new battery now the brake lights arent working properly but the bike is still runnin good

HI. Did you try to adjust the round black switch thats controlled by the pedal?

Does the light work if you use the handle bar brake?

Do a few tests and post your findings.
