Essential Spark Plug Guide for the 1996-2000 Husaberg FE400
Avoid starting problems and keep your engine running strong by choosing the correct aftermarket spark plug for your bike.
- For the 2000 model, verify you are buying the NGK DCPR8E (or equivalent) with a 12mm thread, not the incorrect C8E with a 10mm thread.
- NGK is the highly trusted OEM brand; a standard plug is great for regular maintenance, while an iridium plug is a worthwhile upgrade for longevity and spark performance.
- If you have a 'no spark' or 'weak spark' issue, a new plug is the first step, but the stator is a common failure point on these bikes.
- Always check and set the spark plug gap to the correct specification (0.6mm for the DCPR8E) before installation.
Signs of a Failing Spark Plug
A worn-out or fouled spark plug can cause noticeable problems. If you experience any of these symptoms, your spark plug is the first and cheapest place to start your diagnosis.
- Hard Starting: The engine turns over but struggles to fire up, especially when using the kickstarter.
- Engine Misfires: You might feel a stumble or hesitation from the engine, especially under acceleration.
- Rough Idle: The engine doesn't sound smooth and consistent when the bike is sitting still.
- Loss of Power: The bike feels sluggish and doesn't accelerate as quickly as it should.
- Engine Stalling: The engine may cut out unexpectedly during a ride or when coming to a stop.
Common Ordering Mistake: 10mm vs. 12mm Thread Diameter
Pay close attention when ordering. Many parts catalogs incorrectly list the NGK C8E plug for the 1996-2000 FE400. The C8E has a 10mm thread diameter and is incorrect for many of these model years, especially the 2000 model. The correct plug for the 2000 FE400 is the NGK DCPR8E, which has a 12mm thread diameter. Always verify the plug specifications before purchasing to avoid getting a part that won't fit.
Choosing the Right Aftermarket Spark Plug
The original spark plug was made by NGK, and they remain the top choice for quality and reliability. Aftermarket options from reputable brands like NGK and Denso are just as good, and in some cases better, than the original part.
Brand & Quality Tiers
- Tier 1 - Premium (Iridium): Brands like NGK (DCPR8EIX) and Denso offer iridium spark plugs. These are the best you can get. The fine iridium tip creates a more focused, powerful spark and is extremely durable, meaning it lasts much longer than a standard plug. While they cost more upfront, they provide excellent performance and longevity.
- Tier 2 - Standard (OEM-Quality): The standard NGK DCPR8E is the OEM-equivalent plug. It's a high-quality nickel-alloy plug that provides reliable performance at a great price. You can't go wrong with a standard NGK for regular maintenance.
- Tier 3 - Economy: Brands like Champion offer a budget-friendly alternative. While not as popular in the Husaberg community, they can be a viable low-cost option if you're in a pinch.
Installation Pro-Tip
The spark plug is located in a narrow channel in the cylinder head. You will likely need a thin-walled spark plug socket to reach and remove it without difficulty. Also, always check the gap on the new plug with a feeler gauge before installation and apply a small amount of anti-seize compound to the threads.
Aftermarket Spark Plug Cost (1996-2000 Husaberg FE400)
| Plug Type | Brand Tier | Estimated Price Range |
|---|---|---|
| Standard Nickel | NGK, Champion | $4.00 - $15.00 |
| Premium Iridium | NGK, Denso | $15.00 - $58.00 |
Frequently Asked Questions
How often should I replace the spark plug on my FE400?
For a high-performance dirt bike, it's good practice to inspect your spark plug every 15-20 hours of riding and replace it at least every 30-40 hours, or once a season. An iridium plug can last longer, but regular inspection is still key.
Is an expensive iridium spark plug worth it for my Husaberg?
For many riders, yes. Iridium plugs offer a longer service life and a more consistent, strong spark which can help with starting and throttle response. While they won't magically fix a poorly tuned engine, they are a solid upgrade for reliability and performance.
What is the correct spark plug gap?
The correct NGK DCPR8E plug specifies a gap of 0.6 mm. While some plugs come pre-gapped, it's crucial to always double-check and adjust it with a feeler gauge before installation.
What if a new spark plug doesn't fix my 'no spark' issue?
If you have confirmed you have no spark with a new, correctly gapped plug, the problem likely lies elsewhere in the ignition system. On these Husaberg models, a faulty stator is a very common cause of weak or no spark. You should also check the ignition coil and spark plug cap/wire for proper resistance and connection.
