SOURCE: Speedo not working
Ok have a look at the back of your speedo there should be a black cable with a silver screwcap that runs into the back of the speedo case unscrew the cap inside the cap there is a cable with a triangle shaped end give it pull with a pair of plyers if it does not come out this is a good thing your cable is not broken if you can slide it out of t it 's housing then you need yourself a new one.Also if it is not broken follow it down to the front wheel there is another cap unscrew this end it should be the same triangle shape cable inside as the other end if not it has broken off at this end .

ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.
Please rate this solution. Thanks!

This is caused by air leaks between the carb and cylinder. Tighten the carb / intake clamps and mount screws. If that doesn't help, tighten the cylinder and head down and reset the valves. If that doesn't help, replace the rubber seals and rubber manifold components and the problem should disappear. If not, do a compression check. The exhaust valves may be burned and letting un-carbureted air into the cylinder thus leaning the fuel mix.

yes that is normal as when you do this you are puuting the bike in gear and with the rear wheel of the ground the engine ticking over is just enough to get the rear wheel spinning but not always enough momentum hence the clunking sound of the engine
