Do the following test:- (1) check if theres sparks at the spark plugs, (2) check if the spark plug/s are getting wet with gas.
If the plugs have fouled up i.e. turn blackish due to too 'rich', you better replace them and retune the engine.
Check the valve clearance and adjust accordingly and also go thro the air-mixture screw/s ...tighten them in slowly being careful not to tighten them too hard to the last to avoid damaging the tip of the screws.
Try to start the bike's engine should start taking into account tht its now got a new set of spark plugs and let it run to some good temperature thn set the air-mixture screw/s:-
release to 2 and half turns (turn outwards).
From the sound and the running of the engine you would know if its at its running ok can however go in or out + - a little to get good idling of the engine ...go for a spin and recheck the spark plugs to its condition and offcourse for the starting issue if its solved.
Hope this helps!

It takes to lot start it wont stay running if i have the chock out part way out it will run but it needs head gasket could it be that

If it needs a head gasket, what else is wrong.? It won't run right at all without the proper back pressure, Is it water cooled? Also sounds like the slow speed jets are clogged, did it sit for a while? Need to check that out, those things have to be spotless, or it won't idle or start. Hope this helps.

if it takes a charge off the bike on the bench, (if not replace it) check your fuses.If you still cant run it, the volt regulator (rectifier) may be bad.

the right handle bar round thumb button is the starter and the run/kill rocker switch should be in run position to operate elec starter
