Partzilla Live Q&A Highlights – Honda ATV Questions

What’s a good price for a Honda 400 EX? I was looking for 2002-2008’s and where I live they go for $3,000.

John Talley: That’s probably a fair price. The ones that I looked at were anywhere from $2500 to $3500. It really depends on the condition, but the real trick with those is that you can’t tell how many hours you have on them. I’m pretty sure we did a short video of what to look for when buying a used ATV. … One of the telltale signs, which I think I mentioned in the video is that when you pull the dipstick, go ahead and smell the oil. Was it changed recently? Were they just being that fastidious about their maintenance or were they trying to hide something? But look at the dipstick and see if it has a burnt look to it or if old oil has been there for a long time. That’s usually the giveaway, so take a look at that very carefully when you go take a peek at it. 

Do I need to get a new hub on my 2000 Honda Rancher TRX350 if the bearing just pulls right out of it? 

John Talley: If it’s actually spun, the outer bearing in the hub itself, then yes, that can be a big problem. You might need to go ahead and replace the hub on that one. I think we did a bearing replacement video on a TRX, although it may have been the 420 and not the 350. But the general way it comes apart and back together should be pretty close. 

On my Honda 400 EX, on the front brake master cylinder the plastic that unscrews to put in more brake fluid has stripped out. Any ideas on what I can do?

John Talley: Alright, if you’re talking about the cover on top of it, where you have to remove it to get down to it, there should be Phillips. One, you want to make sure that you have the right bit because the standard Phillips that you pick up at whatever store doesn’t quite fit in there correctly. I believe it’s called an NT tip, and if that’s already stripped then you want to get an NT tip with a hand impact. So it basically looks like a screwdriver. It has the tip on there but you hit it with a hammer, it drives the bit in and that’ll usually break it loose. … The most important thing is to get the correct tip. I think it’s called the NT, that’s what’s coming to mind right now, but you want to get a tip specific to those particular Phillips.
