Why is my Honda Foreman backfiring?
What Causes Backfire? When the engine on your motorcycle has an emission system malfunction, such as an exhaust leak or a moment of running rich or running lean, backfire occurs as a result. When an engine is running rich, there is more fuel present than there is air.
What causes my four wheeler to backfire?
ATVs usually backfire because of a short, sudden moment where the engine is running too rich or too lean. That means that it’s either getting more fuel than it needs for the amount of air it takes in, or else not enough.
What’s the problem with Honda 450 Foreman backfiring?
Put it all back together and problem is EXACTLY the same. Idles perfectly, but when you hit the throttle it backfires through the carb into air box and chokes to death. I dont know what else to do. Please help! Thanks
What did you do to fix Honda Foreman es?
Thanks guys! I have a 2001 Honda Foreman ES that started doing the same thing today (no oil in air chamber). Idles fine, sputters and dies if you give it gas. Gas is flowing fine to carb. What did you do to fix?
What kind of engine does a Honda Foreman have?
Other machines can do it as well but the design of the 450 seems to do it the best (and the 400 Foreman). My 450 is a 2002. When I rebuilt the top end it had a lot of carbon build up on the piston and valves. I cleaned the head and ground the valves.

Why does my Honda Foreman die after 10 minutes?
See title: runs fine for about 10 minutes then starts cutting out, backfires, and dies. Let it sit a few minutes and it starts again…repeat. I think I’m narrowing it down to fuel delivery and/or exhaust leak.
