Honda Foreman 400 Specs and Review 2022

Honda Foreman 400: Also called the FourTrax The Honda Foreman 400 impressed the market upon its debut in 1995.

t was a single-cylinder, 4 stroke engine, all-terrain tires, and steel racks that were built-in It was the choice quad for those working in the industry, ranchers as well as hunters and off-roaders. 

Honda Foreman 400

The 400 was a step up over the TRX300 and was a glimpse of what was to be offered by Honda.

Foreman 400 Honda Foreman 400 was Honda’s entry into the utility ATV class. It had a speedometer, triple drum brakes, as well as an overhead-valve design. This was also one of the first Honda ATVs to have a longitudinally mounted engine.

Transversely-mounted engines were revolutionary, and it was replicated in other models such as Honda’s Honda Recon. 

The quad also functioned as a solid foundation since its weaknesses helped build Honda’s current utility vehicles.

Let’s review the history, specifications, and concerns, as we discover more about Honda’s top utility ATV.

What’s the deal? Honda Foreman 400

In its debut in 1995, the Honda Foreman 400 was by far the biggest ATV manufactured by Honda. 

The Japanese manufacturer created the Foreman 400 as a heavy-duty utilitarian vehicle designed for hunter, towing light, plowing, camping as well as hauling and dumping equipment. 

Exterior updates and attachments from the aftermarket were available from models from 2001 to 2004. While it was 50 pounds less than the other models because of its engine mounted longitudinally, it was still not an extremely light four-wheeler. But its innovative design and all-wheel drive more than made up for its weight and made it adept off-road.

It’s Honda Foreman 400 also featured an overhead valve design that reduced its height and provided greater ground clearance. 

Its wide ground clearance, combined with the robust suspension, enabled the quad to glide smoothly over gullies and rocks of a mid-sized size. 

The rear and front racks offered ample room to carry various camping equipment or trees from the woods. 

Its low-end torque, grunt, and simple-to-use reverse gear allowed towing and traversing sections that were slow to crawl over easily. 

In a matter of minutes, the Foreman became the preferred choice for hunters, recreational, and farmers.

This 4×4 was able to keep its basic design throughout its nine-year production period. Exterior enhancements were only available for the 2001 model after it was announced that Honda’s Foreman TRX400FW had reached its end of production in 2004. 

Additional options included an AM/FM radio cassette with speakers CB radio high-performance exhausts, lawnmowers power blades, oil cooler or plows, snow blowers as well as a utility trailer and winch. 

Then, Honda released a high-performance sport ATV that had identical engine capacity in 1999.

It was the Honda FourTrax 400EX. The Honda Foreman 400 and the 400EX were extremely popular and were visible throughout every race and ride track across the U.S. In the U.S., the Honda Foreman 400 was a popular ride for families and for those working in the agricultural sector as well as the FourTrax 400EX of Honda was a rousing addition to the ATV sports industry that was slumbering in the decade.

Honda Foreman 400 Issues Ignition Problem

Sometimes you may notice that it happens that the Honda Foreman 400’s neutral indicator does not light up when you switch off the engine. 

This issue can be quite a hassle since the wiring diagrams included in the Honda Foreman 400 service manual aren’t specifically addressed to the problem. 

If you do encounter this, the two first items you need to determine are your battery as well as your 30-amp circuit breaker. 

If either of these is checked out the 5-pin connectors. They are located beneath the seat cover, while the other is under the handlebars. 

To test, you may utilize a jumper cable, or conduct an earth test on the hotwires that are connected to the respective wires to find out which area’s power isn’t flowing. If that fails, you should seek help from your mechanic.

Leaking Carb. If you believe that the reason is the result of the gas shut off make sure the valve is closed and not in reserve. It is also possible to remove your carb and examine the floating. 

If you are able to pull gas from the edges of the carb with your fingernail by pressing it against it while holding the needle, and seat valve in place, it’s probably submerged and sinking. 

The seat is supposed to be clean and free of no rust, and the needle (if made of metal) is smooth and smooth along its sharp pointy tip and does not have a scratch mark caused by the seat. 

In the event of a problem, you’ll require an entire replacement needle seat as well as a rubber tip too. Make sure the float is at the right level, and determine if it’s been taken separated before and may require an adjustment.

High Idle

This type of idling usually happens after a replacement of the carb and can be identified by the glowing exhaust coming from the motor. It could be caused by an air/fuel screw that is not properly set up or a CDI issue. Check that the throttle screw is back and your butterfly valve completely shut, and your boot that connects the carb and motor is in good condition. 

The air or fuel screw should be somewhere between 2 and 2 1/2 turns away from a lightly seated. When replacing your carbs check the jets of the new model with the older ones to ensure an exact size that is a good match. 

If you do not find any issues with these parts, then installing a brand new CDI electric starter will let your vehicle perform as well as the best.

Intermittent Idling

If your quad fails to get fuel through midrange however it runs well at higher RPMs, ensuring that the rectifier and regulator aren’t overheated. 

If they are not it is possible that additional Honda Foreman 400 parts like the taillights, headlights, along with engine control unit, could end up being affected. 

Tanks, fuel lines along with the fuel filter inline, air filter, and carb must all be thoroughly cleaned and sanitized with no foreign materials. A new spark plug could also aid. Make sure there are no leaks from the vacuum.

A sonic cleaning device can help to thoroughly clean the carb, however, the process between the pilot jet and the pilot screw is sometimes partially blocked. The carb should be soaked in warm water and soap for two hours should completely dissolve the accumulation. 

After that, with both the pilot screw and the pilot screw put your fingers over the tiny pilot screw hole in the bore of the carb and use a compressor to blow through the hole to clear any obstruction.

Other issues to check are whether the float level is too high or a vapor lock or a leaky primer pump. The four-wheeler is likely to display signs beyond half throttle when the voltage is excessively high at idle.

Choked Up Acceleration

It is possible that the engine is starving for air following a smooth start-up or an idle that is stuck at high after you hit the throttle. 

This can be fixed by rebuilding your carb and making sure you replace the diaphragm as well as the needle/plunger along with it. 

Examine the safety wires of your quad for the parking brake since it can cause problems with the timing while the brake is turned on. 

Check the boot between the carb and engine for holes or tears. Spray a small amount of cleaner for your carb onto your boot, between the carb head and the cylinder head.

If the idle fluctuates and you notice a change in the idle, then it’s an air leak that has been confirmed.

If you clean the carb, look for dirt in the fuel and petcock lines. The presence of alcohol in winter blends may cause the formation of the residue. 

Use a fuel filter too. There are also tiny orifice tubes inside motorbike carbs that are able to be cleaned. 

Utilize a brake cleaner, and spray it through the small tube that the can is packaged with, and then high-pressure air. Spraying and dipping without removal of the tube will not work.
