possibly 50CC or more
i live in Hulme which is in Manchester in the UK
is there anywhere in manchester thats Local to me where
i can go and buy a Mini Moto
Thanx

this dirt bike is a 4 stroke
its easy to kick its just when i do nothing happens.

I'm going to make a guess and assume it's a Chinese Clone of a little Honda engine.
Normally,,all those type motors are very easy to start if the engine is in Good Condition,,,or even fair condition.
———————————————————————–
Some things that can make them hard to start.
*Low Compression.
That can be caused by several things.
You Really need to have the compression checked with a gauge to determine if it's within proper range.
Should be about 120 psi minimum.
If it's Less than that,nothing will really help much.
"Low Compression" is usually thought to mean "burned-up / wore out Engine",,,,and that's often true.
But not Necessarily.
Valve Clearance Adjustment,,and Timing Chain condition will affect it also and make the compression a bit lower.
>>>Adjust the Valves to .003"
That's Looser than recommended setting of .002".
>>>Make sure the cam chain is adjusted right.
Sometimes the adjuster "sticks" and doesnt really work right.
Also need to check the chain for wear.
Both things are easy to do.
CARBURETOR:
These things are so small even the Tiniest amount of gum/varnish/deposits will make them behave badly.
Easiest thing to do is try some Cleaner added to the Fuel tank.
Use FUEL INJECTION cleaner,,,not "carb cleaner"—it works much better.
Chevron Techron ,,or Seafoam are 2 good ones.
Don't Overdose it thinking that "more is Better".
You may ultimately have to remove the carb and take it apart to clean it.
The Intake Manifold "never" gets loose on original,genuine Hondas.
On all the Clones,,,,it's a crapshoot.
If they Do get loose the Gaskets will leak air,,and cause hard start,bad running.
Or,,if Carb has ever been removed ,,,it's tuff to get them to re-seal without using new gaskets.
Ignition System/Spark Plugs:
Most of the late model versions all have electronic ignitions.
They usually work OK,,,and are Usually NOT adjustable.
When they FAIL,,,almost always it fails like a Light Bulb.
They just Quit Working at all,,,,no mysterious misfires,,no intermittent problems that come & go.
So IF it sparks,,and eventually Runs,,,
there's 99% Odds the CDI Ignition is working OK.
Spark Plugs.
Try an NGK Iridium Plug.
DO NOT expect it to "FIX" anything,,or even Cover-Up any sort of problems elsewhere.
Make sure everything Else is in good order First.
They are NOT Magic Plugs,,,but they DO improve starting because they can fire under a much wider range of conditions,,including Weak Ignition system,,,or partially flooded,,,very cold temps,,,etc,etc
They're expensive ,$8~10.
It Wont FIX anything,,but they can definitely help
Get a Service Manual if you can.
If You cannot find one,,,early Honda 50 & 70 Manual is Close enough to give You general basics
…………………………………………………………..
You will have to register,,but You can get Free Manuals here
http://www.repairmanualclub.com/
These will help.
Remeber,,these are NOT Identical to Yours,,not even the same engines,,70's and 90's are Different.
But they can give you an idea how the things are laid out,,,and valve adjustment,timing chain stuff is basically the same.
Carb Clean/Rebuild PROCEDURE is sorta generic,,,things like that.
Consider them only HINT,CLUE,or GUIDE,,,,and NOT actual,accurate service manuals for Your bike

Good Luck with it
it wont start when the choke is off so i turn it on and it starts and after a while when the engine heats up i turn it off and it cuts out…..
i have to keep the choke on all hte time and it goes but very slowly!!

Strip the carb bowl off, remove the float assembly
where centre bolt attached bowl, inside that tube is the jet and emulsion tube
Carefully unscrew this jet and clean with compressed air or if your lucky your breath ??
Muck in the carb…. but they are not the best quality
I have bought several none runners off ebay and everyone its been a quick fix …. dirty carb
Try and put a small inline filter within the line …. I modified them with a longer hose to adapt them and had no problem
If the carbs mullered….. you can buy them off ebay for £11 + delivery
Oh….. have you checked the reed valve after the carb… ? sometimes these break or dont seal correctly ??
This might be the fault you have…. due to choke ??

Any ratio between 32:1 and 40:1 is OK.
32:1,,,,That's 8oz of oil per gallon of gasoline (US)
Or in Liters,,
32 militers oil to 1 liter petrol
125ML Oil per 4L petrol

anyway, I would highly recommend you do as a minimum the following things.
1. pull out the spark plug and thoroughly clean it. stick it back in the spark plug cap, using insulated pliers, hold the little finger thingy that bends up over the center electrode to the cylinder or head (ground the finger) and kick thru the kick starter … watch for a spark… spark is a good thing !!! if no spark, take to a mechanic as it will be difficult to describe here to the level of detail for you to get it going… if it does have spark … continue to step 2 below after reinstalling spark plug and spark plug cap.
2. with gas petcock turned off, remove the screw on the kick starter side of the lower float bowl to allow the old gas to run out. turn on petcock to insure that gas is flowing thru to the float bowl. if gas flows out, reinstall the screw… if no gas flows out, turn gas off and remove carb, disassemble and thoroughly clean with carb cleaner (berymans, chemtool, etc.). reassemble and reinstall, repeat earlier step to insure fuel flow…. fuel flow?
3. without touching the throttle, turn on the choke, depress the kill switch button, kick the bike thru slowly about 8 times, let off the kill button and kick the kick start thru quickly trying to start the bike. try this 3 or 4 times and the bike should at least "promise" (act like it fired) if not start. if nothing. replace the spark plug with a new plug and try again. if still nothing… probably be better served to take to a mechanic…
hope that helps and you get it started.
I hate EBAY except for somethings.

used gas ones go for around $200
i want it to be nice but not to expensive because he will soon grow out of it.
thank you!
