hello all im a 1st time 4wheeler owner and have purchased a 2019 honda rancher420 4x4 and im just wondering what mods are everyone doing and what are the best things to do for more power im sorry for the noob questions lol thanks in advance

 

Should have bought a bigger faster machine to begin with. Those Honda machines are designed to be good running reliable machines, not made for performance. Not sure the very small gain in performance would be worth the money and effort.
besides any mods will void any warranties....

 

I was thinking about a gear reduction. its a great quad just tends to bog down in the mud. even worst in 4wd

 

That is not a high powered machine to begin with, so the cost of rebuilding the drive line to get more power may be cost prohibitive. Not being a smart *** here, but you might consider selling your Honda and buy what you really want. Your not alone here, many folks find there first machine is not what they really wanted or it wasnt what they thought it was going to be. When I got into 4 wheelers, I spent months researching and test riding to find the machine I wanted. After 16 yrs of quads, I moved into a UTV, and spent another 4 months researching and testing b4 I found the right one.

 

I agree, though the 420 is quite powerful for a Utility quad. A few years back farmers all had Honda 350s, 350 Big Bears, Kawasaki 300s etc, and were happy enough with the power. Also bigger engines do not automatically mean better in mud, a local farmer who tried both, reckoned the 450 King Quad was better than the 700 King Quad in slippery mud, as the lower torque meant the wheels didn't spin as much. If you do just want a bit more power, the 520 Honda is almost identical, but has diff lock and more power, but you don't seem to want a utility quad at all, look at what others doing the same thing, are using.

 

Some solid advice here with it being a smaller machine. It would be very hard though just to walk away from a new purchase like that to upgrade without losing your shirt.

What kind of tires do you have on it? If you have the factory tires and looking for better mud performance start there. A one size up set would be ok, Zillas are price friendly and perform well in mud.

For or a little more power, KN air filter, jet kit and FMF muffler where you can adjust the restricter plates. Depending on how you want it setup this can either give you a little more down low and lose some top end or lose a little down low and gain some top end. Won’t gain you much, 1 to 2 mph top end or you can feel a little more jump off the start. Should cost you less than $500, most may not find the change great enough for that but it may be that little extra you want. Be mindful of your warranty while doing this.

 

If I remember right the Rancher doesn't have a low/high range transmission like other makers' machines. As others have said this limits the quad on low end power. 1st gear is pretty good for a 420 but not like the power you would get from a competitor's 450 or above class with a low/high range transmission. I haven't been on one in a few years. Competent machine but not a powerful mudder. One of the keys in getting through mud is being able to spin the tires fast enough that they spit out the mud during rotation so the tire doesn't clog and become, essentially, a slick.

 

From one new member to another, welcome, and congrats on the Rancher!
