Hi Blu, I haven't had a motor bike for a while but is there NOW gearbox oil as well as engine oil???.... Use to be the same mate, You should ask next time you're in the local motorcycle store..... CHEERS..

Probably a carb issue. It sounds as though the idle jet is clear but the main jet is blocked. So your bike starts and idles, but as soon as you ask for more fuel, not enough gets through the main jet and the bike bogs down. Buy a manual and a can of carb cleaner, take the carb off, remove the bowl, remove the jets and leave them soaking in carb cleaner overnight. You might need to use some fine wire to poke through the jets if they are very blocked..

if you turn the key on and the gauge goes to overheat immediately ( hasn't been running and is cold) that indicates a fault in the wiring to the temperature sender unit ( probably fell of the unit and is touching on the engine or head or frame ) it may have a coolant temperature sensor ( tells the fan when to turn on if stationary) and that may be faulty

Hi the easiest thing to check is the spedo drive at front wheel lift front wheel off the ground and spin wheel if you look in where the cable goes you should see it turning. If not the drive needs repair or replacing. Regards Jim...

That could be one of many things, could be a tight valve clearance,fuelling problem ,ignition failure.all of these can fail when the bike has just run for a bit,the primary ignition and secondary ignition coil can fail from the heat it generates and the valves tighten as they warm.up through thermal growth.and the fuel goes down sometimes faster than it can 've delivered.these hikes have a pneumatic fuel pump and the vacuum pipe that operates it falls off the inlet manifold which stops it pumping.

I would check a few things. First off make sure the throttle cable is adjusted correctly. Second, try opening the throttle half way and letting go you should hear the inside parts of the carb click as they seat. Third, find the idle adjuster screw turn this anti clockwise and see if the idle speed drops down. Fourth check the choke mechanism is working properly choke/cold start forces a rich mixture to the engine and increases the idle revs. it is worth checking the pilot air screw is adjusted correctly. Hope this helps.

If it's dripping fuel fix whatever is making it dripped petcock or the fuel line. The reason it's dripping more one is running is because it's sucking the fuel from the tank to the motor fixed the leak. If you too lazy to do that and wanted temporary fix. Get a bar soap, and just smear it around wherever it's leak in and the soap. The leak. It's an old trick

Check the regulator. Might be damaged.

You are a bit short on information to get any help - "doesn't work" also doesn't give anyone a place to start. WHAT DOESN'T WORK?

start a fresh ! plug out and turn piston to tdc and mark flywheel ! have you moved the timing plate ? soz i dont know the degree time this is just to help!

If it is water cooled first check the coolant level also the temp sensor switch on the engine that turns on the fan also the temp problem could be a bad thermostat or a bad fan the engine cutting out could be due to over temp I have also seen this happen due to a bad kick stand safety switch if yours has one

call your local dealership or try ebay.com or you can look into some after market options. look up motorcycle parts catalogs.

From your description (keeps overflowing,spark plug always wet), it sounds like it's flooding. Because of the overflowing, possibly your float is set too high, or some crud is lodged between the float needle valve and it's seat, not allowing it to seal shut when the float bowl is full, then flooding the carb's mixing chamber.
