check you got power comin out of the stator wires when crankin ! check the plug cap resistance isnt too much if its a resister cap as this will reduce the spark also ! try without the cap on and hold near earth and see if it sparks ! soz not got resistance values ! check flywheel key not broken also !

What have you inspected so far. Thank you for the vehicle description and the symptoms but I need more details about the maintenance history, any recent repairs, and so on. This failure could be external or internal. You are the eyes and ears of this bike. How is the chain and both sprockets? Is the chain stretched and the right size? With the trani in neutral, does the bike move (role) freely? Run some tests, look at the fluid inside the gear-box. Does the fluid look ok? Do you see any metal floating around? What color is the fluid, does it look bad or burnt? Please write back, good luck.

White smoke! If your bike is water cooled it's not good. Check your oil. Just look at the dipstick after a short ride. Is the oil foamy looking? If so water from your cooling system is making its way into the crankcase. Unfortunately this is major.

possibility that even though you have good compression the pressure below the piston is possible leaking past the crank seals ! weak draw on fuel in !

think u hav fuel injection--probly a worn fuel pump or regulator-if a carb-the float is dirty or the fawcett at tank is clogged--buy a clymer book for troublshoot details

you have not fitted the correct spacers

change the rectifier regulator ..to much power going to bulbs

replace the water pump or mechanical seal .. or both

Thee are several things that control the current available to the spark plugs first is the quality of the plug leads and if they are in the resistance range specified. Another is the state of the coil/s. This may be rectified by new better coil/s If you have a condenser in the circuit it has to be in top condition or it will not activate the coil/s to max voltage. Battery condition will be a factor as a failing battery will not supply the correct voltage for anything to work well

Check spark plug.
