Hi

I am new to pocket bikes and pocket bike racing. I have recently bought a mini dirt bike off ebusiness supplies off ebay. I have started it up a couple of times with great difficulty, i gotta pull like 10 times. This is the link to the bike i bought http://cgi.ebay.com.au/ws/eBayISAPI....7426&rd=1&rd=1. The other problem is that when i start it up the bike doesnt have enough power to move anyone only enough power to barely move the wheels. Could you please give me any suggestions and if possible please provide pictures as i do not know where anyhthing is in the bike.

Thanks

there are many places to start. go to your users manual, yes you have to. sorry.LOL....... go through the checklist of items and check thourgholy. make sure you are using fresh gas and that the bolts are not to tight on the rear axle causing the tire to stick. a new plug is a good idea also. anyways , start there.

Check the adjustment on the rear brake as well.
Does the engine rev up?
Is the problem with the bike or the motor?

umm yer the manual is pretty useless it doesnt tell you anything about the actual bike only about pocket bikes in general and what do you mean by checking the rear brakes?

I was just thinking the rear brakes might be hanging up, and keeping the rear wheel from turning.

I was also wondering if the motor was reving up and not moving the wheel, or the motor wasn't running properly so there is no power to the wheel.

Thanks for your suggestions but i can still move the bike forwards and backwards without the engine on so i dont think it is the actual wheel or the brakes that is causing the problem. When i turn on the bike i can revv it fully and it only just has enough power to move the wheel. I think it might be the engine or something which is not allowing the engine to send power to the wheels? Do i have to remove something or clean something when i got the bike?

if the bike seems to rev up good, check to see if your clutch is slipping on the end of the crank. many cags don't use a key on the clutch side of the crank and if it,s not tight enough the crank can spin inside the clutch. i,ve only seen it once but it,s worth a check

lol i dont have any idea what you are talking about sorry. when i open the cover up i found the clutch and it was pretty dry as in no grease etc.. on it. there was a spining thing inside the actual case?

ok when you take the gear reduction/clutch drum off theside of your engine, you will see the clutch inside. it should have 3 shoes. then take the pull start off the other side, you'll see the flywheel inside( aluminum with fins). hold the clutch with one hand and try to turn the flywheel with the other, if the clutch stays stationary and the flywheel turns you've found your problem. other than that make sure your clutch has all three spings on it. let me know what happens

NiteshDude this will be your answer to all
your problem....First put the bkie on a stand
so that the rear wheel is off the ground.
Remove the left side cover on the motor.
that will expose the clutch and drive gear.
The clutch is a "centrifugal clutch"
meaning when the motor revs up
the shoes expand outwardly, comming
into contact with the inner clutch bell housing.
Its that round thing that came off in your hand
when you removed the cover...Now Dude remove the
chain. Now the clutch has three curved things with
a kindda pad thing glued to it...see 'em, they also
have springs attached to the inside of the curved part.
Dude thats the clutch, when youv'e learned this part...
you'll understand how the motor turns the rear wheel.
Now start your motor being careful not to rev the motor
to high....when you give it a little throttle, the curved things will
start to move out wardly, kinnda like a dragster rear tires
grow real tall on a take off. If the
clutch shoe/pads/curved things are not expanding,
thats the problem. Its a quick fix.....Toss it off a cliff
and go buy a BMS and have a great time racing it My Friend.
Or not, and keep it and Learn how to identify all the parts
and to do that you gotta learn your mini and why and how it works
first, then ask why it wont go or how to fix it when it wont go.
You'll be surprised at how quickly you'll learn it and ride
the living crap'e outta it 'till it dies.
