How do you fix a four wheeler that jumped time?
Resetting Timing
- Remove cam covers and set crank and cam sprockets to TDC on compression stroke.
- Remove the tensioner.
- Remove the chain from the top of the sprockets and hold.
- Realign the sprockets.
- Refit the chain.
- Reload the tensioner – screw-back to reload.
- Fit tensioner plus new gasket and torque to spec.
What does it mean when an engine jumps time?
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all.
Can you fix a motor that jumped time?
There is no easy way to correct a jumped timing belt. You will need to disassemble a portion of the engine to gain access to the belt tensioner, so you can move the belt back into position. I suggest replacing the belt and tensioners while you have it apart, so you don’t have this problem again.
What to do if you have a jumped timing chain?
Place the vehicle in park with the emergency brake set. Start the engine but be sure the battery has a full charge and is operating at peak performance. Note the speed at which the engine tries to start, comparing it with a normal start condition. An engine with a jumped timing chain will show signs of very sluggish and slow starting.
What to do when your bike won’t start?
A minuscule screen helps keep gunk out of the petcock, but corrosion and bits of stray material can cause flow issues. Rattling the petcock a bit can help dislodge any blockages, but replacement or a deep cleaning might be necessary to get your bike running again.
What happens when a timing chain has jumped two teeth?
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all. Step 2
Why does my bike not start with a side stand down?
With leaks—whether from cracking, rot, or road damage—you might be able to reseal the line, or you may need a replacement before you’re road-worthy again. Newer bikes (and some older ones) may refuse to start with the side stand down.

What makes a dirt bike hard to start?
If the top end is worn out, or there’s a gasket that’s not sealing (ie: blown head gasket, leaking base gasket) the motor could be low on compression, and low compression certainly will make an engine hard to start, if you can get it running at all.
