Bike got spark and compression but doesnt start try to push but no luck

Ok. Start from scratch just to make sure your not missing something simple. Verify you have compression on your cylinders. If you dont have a compression tester you can always use your thumb and spin the bike over.If you have good compression, then the next issue is spark. Pull off a spark plug wire with a pair of insulated pliers, hold it next to the plug and try to start the bike.If you have no spark then that is your starting problem.If you have good spark, then your last issue is going to be fuel. But I am betting you have a spark issue. Good luck.

if its a 2 stroke then you need fuel spark and air to get the bike to start have you got compression? check it by removing the spark plug and put your finger over the hole air try and start the bike your finger should be pulled into the hole if not then a piston ring is either cracked or broken

open the air box and check the filter then clean the carb thats all you need for a 2 stroke

if its a 4 stroke then again check the air filter and compression remember that a 4 stroke doesnt have the oil with the fuel it goes in a separate chamber

hope this helps

Check for spark,Check to make sure its getting gas,,,Do a compression test on clinders, that should solve it,

always remember if you have "Good Spark": (big fat Blusish spark), not reddish-purple...and "Excellent fuel delivery" be it carb or injected then it has to be a compression problem. Could be valves not closing all the way, you may have to take the top end off and to inspect. Does the bike at least push start but run. if it runs it may be a fuel issue but if it doesnt even push start then it got to be a compression problem.

if the bike will not turn over you mean it doesnt crank? because if it doesnt crank over then its a starter issue and could be a simple as a blow fuse, but then why did the fuse blow? ( starter going bad)..... or it could be the starter solenoid itself, and this is where i believe you might find the fuse. response feedback appreciated.

Just because a spark plug fires outside the motor doesnt mean its firing under compression. Start by making sure you have new spark plugs. If that doesnt help then do a compression test on all cylinders and compare.

no, i leave mine on all the time! unless you have a sticking float ...that might let fuel creep into the cylinder over night and cause flooding...turn kill switch off, choke closed, throttle open full max, then crank for ten seconds then let set for about a minute to let starter cool down then see if it starts. if that doesn't work then try to push start it..if that doesnt work then take it back to the repair shop.

the bike might have to much oil in the bike so when you try to kickstart it, it sends oil to the piston and soaks the spark plug in oil. But when you push start it the spark plug is going alot so it catches, just kicking it doesnt give enough spark tho. my bike doesnt the same and then somtimes i have to take the spark plug out and clean it with a wire brush then usually its fine. Or you could have the wrong oil in the bike, i would read the maunal to find the perfered oil. hope this helps

Could be a fouled plug. Did you check that? Is it a 2 stroke?

Hi,

You need to inspect the valve clearances. It is common for the intake valves to wear a little.
Inspection of the clearances should take place at 15 hour intervals if you are racing the bike.

When the valves leak, the bike does not maintain compression and kick starting becomes tough. The fact that the bike starts when being bumped, shows a loss of compression.

An easy DIY compression test is to remove the spark plug, place a finger over the plug hole and press down on the kick start lever. The air should be forced past your finger at a high rate and you should hear the air escapeing. You must not be able to prevent any air from escaping.

Good luck
