Why does my Honda FourTrax 300 have no spark?
I have been working on a 1990 fourtrax 300. I have no spark at all. I have checked all fuses, checked all of the connections, replaced the coil, checked the kill switch, replaced the CDI, and replaced the starter (not the problem but needed changed anyhow). The motor will crank but that’s it.
What are the spark plugs for a Honda 400ex?
The two NGK plugs that are made for the 400EX are DPR9Z and DPR8Z. The 8 is a hooter plug for winter/cold weather riding and the 9 is for summer/hot weather. The DPR8Z is the stock plug. The DPR9Z is for extended high speed operation. Thats what I read in the manual anyway. The number represents the heat range of the plug.
What should I do if my Honda Foreman 400 has no spark?
Spent $100 on a new OEM unit but nothing changed. Back to square one staring at the electrical diagram. Consulted the forums again as well as the dealer and parts house. Next suggestion was replacing the ignition coil. If not that, could be the stator or ignition pulse generator.

How can I check my spark plugs on my ATV?
It’s best to look through your service manual to see what your ignition coil should read on its primary. Next lets test the secondary side of the ignition coil. This is the side with the spark plug caps. If your ignition coil has two spark plug caps, simply put the red test lead in one and the black in the other.

Where is the spark plug on an ATV?
Place the spark plug on the cylinder head or near an exposed metal part of the frame. The plug’s metal part must touch the metal on the engine or frame for this to work. This will ground the spark plug so that it can create a spark. Crank the engine and watch for a spark. You may need a helper to push the starter for you.
