  1. So I’ve been working on cleaning out the garage and getting rid of things we don’t use anymore. At the same time we’ve been doing a lot of work on the quads lately. While cleaning, I ended up with a couple of old scooters and an old plywood box that the boys used to throw toys and other stuff in. For the past few months we’ve been using a bucket to put the quads on to do work. I got to looking at the scooters and the old box and came up with either a brilliant plan, or a complete waste of time. Not sure which yet, but I’ve spent the last couple of days working on it and I seem to be making progress.
  2. When I did mine, I didn’t know what condition everything was in. I knew the valves needed to be done, and the seals needed to be replaced. Due to shipping times and not really wanting to be waiting longer for parts. So I just ordered everything. Valves, seals, guides, springs, keepers, the whole nine yards. I also didn’t know how the bike had been treated over the years since we bought it used. I ended up not needing the guides, but I have them for the future. Considering the cost to do it now, or take a chance of having to go back into it again, I opted to do it all at once. As it was, I screwed up and didn’t do the rings at the same time due to what I spent on the valves, and ended up back into it for those a couple of weeks later. Now that we have two of the same machines, if I need to do the second one, I already have some parts for it, and it is an 03 all original.
  3. I’m using Kibblewhite valves now and they are working great. Springs are a bit stiffer. I did seals, springs, valves and retainers all at once.
  4. Welcome to the sight Texas. That is a beautiful 200x you have there. Definitely worth more than you traded for it. Shade and slammedranger have you started in the right direction. Those old ATCs are easy to work on. Best advice I can give you right now is to not skimp on parts. Replace all the bearings and seal there are while you have it apart with high quality parts. After 35 years, you can bet they are a bit tired. Unfortunately when it comes to the bottom end on that, outside of some general hardware, you will most likely need to buy used parts for it. In the transmission, if all the gears and shift shafts are good, they most common thing to wear on them are the shift forks. You will want to mic them to see if they are in spec. A lot f the parts between the 200x, FourTrax 200sx, and the ATC 200s, and possibly the early trx200 were either the same or could be interchanged. Surprisingly, Rockymountainatvmc.com still shows the factory crank, most of the seals, bearings, thrust washers, and shift shafts still available, along with just about everything for the head, including the head itself. There is something to be said about those OEM parts. They lasted this long, and would last just as long again if maintained. The old 80s Hondas were the best for a reason. Too bad they don’t build them as tough as they did back then anymore.
  5. I had Artrax tires on an ‘03 Rincon. First set were 25 and the second set are 26. Great all around tire for the farm and mud. They did well in thick mud that was up around mid tire height. Decent in snow if it wasn’t up to the top of the fenders. Biggest problem was the snow packing up under the frame, usually along the roadside getting into fields where the plows threw it and it would get packed in.
  6. Ahh, towards McCain and 176 area near Burns park. There use to be a little cycle shop right down off of 40 there. Forget the name of it. A bit overpriced, but decent enough. I lived up in Ward when I was there.
  7. Shadetree, whereabouts in NLR are you? I was stationed down there from ‘03-‘13.
  8. I know I’m late to the party here, but just read the entire post (both) and like everyone else, I have opinions on it. I know you can finish this build up yourself and have it run great. They are really simple once you get into them and see how everything works together. If it were me doing a rebuild like this on a 22 year old machine, I would replace every single seal and bearing there is on the motor. I know it is a bit on the expensive side to do it, but for me, it would be a combination of insurance and peace of mind. Yes, some of them may feel like they roll fine, but may either be close to the wear limits, or have just enough wear or problems that you cannot feel or see to cause a problem in the future. If the originals lasted this long, with unknown abuse prior to you taking ownership, then this motor should last another 20+ years if you do this now all at once. Consider all the hours you are putting into this now just to figure out what issues you have. By skimping on some wear items now, you may be doing this all over again in a year or so, wasting just as much time as you are now. I would do the same with the valves, springs, guides, etc. It may be overkill, but for me it would be worth it. It’s apart now, do it all at once and be done with it.
  9. Thanks shadetree. I started fixing things when I was 8 on my dad’s tractor trailers in the early 80s. I’ve had a little experience over the years.
  10. Thanks. I’m hoping I can add a bit of expertise here for others. Been working on the old ATCs and quads for many, many years. Just rebuilt the top end on the ‘07 in June. The ‘03 has never been opened. I also just realized that I said it was a ‘99 in my first post and have no idea why. Hmmm. 🤔.
  11. Hey y’all. Found this site from the Honda ATVs forums website. I’ve had Honda’s off and on since the mid 80s. Currently we have a 99 and an 07 400ex. I get to spend a lot of my time teaching the boys how to maintain and repair these machines. Dave
