exellent quads the 420 is our biggest seller Im a mechanic at a honda dealership

The more I ride these things, the more I love 'em. (And I just LOVE Hondas). I've seen a few other Ranchers around here, but none of the AT models except ours. These puppies will go through (or over) just about anything. I have absolutely amazed at the power these things have for 420's.

Just remember if you do your own oil change that the oil filter gos in both ways but the wrong way will starve the top end of oil.
buy the honda oil filter and it will say" this side and spring towards engine" the other side will say" this side towards cover"
Ive had to rebuild numerous top ends because of that,you can get cheaper oil filters at wally world but I dont think they have the lettering on them.
Id stick with the Honda parts.

Oh, I ONLY use OEM parts. I don't go the cheap bargain route. Honda's will run forever if you take care of them. I aim to. Thank you very much for the advice on the oil filter. I'll make sure I get them in correctly. I already checked my manual, so I know what kind of oil to get for them. They just crossed the 20 hour mark, so it's time for their first change. The mechanic where I bought them said that I need to check the air filter too and make sure that it has the blue spots/patches in it (as that will indicate that it is still properly oiled). He also recommended that I purchase extra air filters. He also said that it was not necessary to take them in for a "break in tune up" as the mechanics at a lot of dealerships will want to take the whole top end of the engine apart, which he said is not necessary with my model unless something is wrong.

Wow man Ive never heard of taking apart the top end on a break in tune up,sounds like somobody wants to make some money.
I also think I may be incorrect on the AT oil filter It may not have the writing on the filter but is printed on the installation instructions that come in the package, the trx 420 tm,fm,(manual shift)te,fe(electric shift 2 and 4 w/d)and the older trx 350s have the writing on the filter I think honda should have made the filters free flow both ways to prevent this but ???dunno why they didnt.

The local dealers are REALLY bad about this. Back when I rode sportbikes, I'd take my bike in for new tires, sprockets, and a chain and the mechanic would want to run my valves. I'm like "What the heck for?" He'd say it was routine on sportbikes. Nope, just the stuff I told you to change. If it starts running funny, I'll bring it back. And they charge a fortune for their work. I really like the mechanic where I bought my ATV's. He was really cool, very honest, and very thorough.
