Bike is sometimes hard to start.When bike stalls and goes dead,it is hard to start again.This is a 2003 honda crf450.

Sounds like the fuel supply can't keep up...check filters and fuel cap breather.

Line from gas tank goes to brass nipple, throttle line goes to top threaded opening, the hole with two bolts alongside it go into the crsnkcase. air line from airbox clamps to the last opening on the carb. The of the openings are vents and overflow.

sounds to me like you have something draining your battery when it sits. something still on or possibly a short

there is clutch oil witch goes on the right side and then motor oil witch goes on the left side.. you should run honda oils in that bike hp4 for motor side and honda clutch oil for the clutch its in a tall red bottel..
about the levels, on the motor side(left) use the sight glass and put it half way. on the clutch side use the small screw thats on the clutch cover for a drain fill it till it starts to come out..but the easiest way to do this is to go by the service manuel specs.. you can call your local dealership to get them also

you got the wrong plug. put it back tin the same way it came out!

you probley have a blocked main jet in the carb take it off and blow it out or take it to a bike shop and get the carb cleaned if you take it off your self they should only charge you about 0.5 hours labour

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

If it is hard to start after it stalls, it is probably getting too much fuel. Could be dirt in the float valve. Also try running a hotter spark plug

its one of those chinese honda clones. i wouldn't worry about it, just keep the exhaust off it, it will run AND sound badass
