Best 300ex service manual

Recommended Posts

So I'm new to the forums tho not to atv's. Anyway, I got a 95 TRX 300ex the other day and it needs some valve seals. The compression is at 150psi, so I assume it has to be the seals that make it smoke. I want to make this thing run better, as it's a nice quad. It's has a racing suspension setup all around, and I don't want to ride around smoking..

Just wondering what would be the best service manual to get for it?

Clymer makes a decent manual, that is the only one I have ever used, so it is the only one I can speak about.

so far short of dropping a ton on a factory manual, i've found the clymer manual to be pretty good, its helped a ton so far, i think haynes is the only other one out there other than the factory one and well from past experiences on a the haynes they dont tend to cover everything. hope that helps

      I saw this article on Motosport and thought it was pretty good. Anyone add anything?
        You might think hopping on-board an ATV and going for a spin is just as easy as taking your regular 4-wheel car for a ride around the block. After all, both have four wheels. How hard could it be?
      In many respects, you're right. Some adventure riders choose quads over their two-wheeled counterparts of the dirt because there's less chance of crashing and it's easier to learn. ATVs also offer more manageability for younger riders to get acquainted with outdoor riding than a dirt bike.
      However, beginner riders on ATVs tend to make the same mistakes that result in crashes, roll overs and injury that could be avoided with some instruction and know-how. If you're looking at a fun family outing by renting ATVs or want to get into the sport take advantage of the following points and avoid the same mistakes so many other first time ATV riders make that end their day early or before they barely get started.
      1. Nerf Bars
      Get Nerf bars. These are not soft cushy add-ons that are cousins to the football you use during backyard football games. In many respects, Nerf bars are gigantic foot pegs. Don't bother with traditional foot pegs because you'll constantly slip off and because of the "I feel safe factor" that comes with riding a quad you'll also have a tendency to let your feet drag when riding. That's a recipe for getting one or both of your feet caught in the back tire resulting in serious injury. Nerf bars allow you to stabilize your feet and get maximum control over the ATV

      Rest your feet easy on Nerf bars
      2. Rolling Over
      Believe it or not, it's fairly easy to roll an ATV over. And you don't want to be on the bottom of that sandwich.
      The most common way of ending underneath a quad is looping out. That's done by hitting the gas and having little to no experience with the power of an ATV. The front spikes up like an out of control stallion, throws you onto your back like a bucking bronco and then pins you like a UFC Champ.
      The second way is when you're having a bit too much fun sliding around in mud or other slick conditions, the tires finally do what they're designed to do and grip the ground but the rest of the bike, with you on it, keeps going.
      Finally, those who think they've found their bearings take aim for a steep slope and try to conquer it only to end up upside down or in their attempt to arch alongside said steep hill, tumble over the side.
      3. False Sense of Security
      This goes somewhat hand-in-hand with the roll over capability that many riders fail to appreciate therefore they also neglect wearing proper protective equipment. Don't think wearing jeans, t-shirt and sneakers is adequate protection when riding a 4-wheeled machine powered by a gas engine that doesn't have seatbelts. You need a helmet, goggles, gloves and riding boots at a minimum. Once you start ripping it on the track or trails add a chest protector, neck brace, knee brace, etc.
      4. Throttle Control
      Everybody wants to skip the kiddie stage and get right into hair-raising speed when it comes to riding ATVs. OK, most everybody. But for those who do so many put on the cloak of invincibility and think a quad is merely a mini car that finally enables them to release all sorts of pent up childhood inhibitions.
      So they jab their thumb into the throttle with the expectation of a controlled roller coaster ride. Instead, they loop out and end up underneath the quad or manage to stay seated only to careen off course and introduce their 4x4 to a large tree. ATVs normally have a thumb throttle and most have an automatic clutch so the clutch is one less thing to worry about. So go slow and figure out how much "thumb" is too much and get used to the speed and power an ATV delivers before really going for a ride. Oh, one more thing, learn to take your thumb off the throttle!

      It's not to hard to loop out on an ATV
      5. Loading the ATV
      Never, ever ride an ATV up a ramp into the back of a pick-up. If you want to know why just go to YouTube. If you want to know how to load an ATV check out this fine piece of quality information on How to Load a Motorcycle, Dirt Bike or ATV into a Truck.
      The bottom line to riding an ATV the first time is treat it like you would anything that comes with a modicum of danger. Careless behavior endangers you and others but with common sense and a willingness to learn you'll enjoy of lifetime of riding quads.

      I have an Outlander 800 XT with 480 hours on it. Very recently the engine power dropped significantly while riding. Soon thereafter the engine created much noise and stopped.
      On opening the rear cylinder I found one inlet valve stem bent and the other broken. The valve head caused considerable damage inside the cylinder.
      My reading is that the timing chain to the rear cylinder jumped at least one sprocket tooth to reduce the engine power, thereby compromising engine power, and then shortly thereafter jumped one or more teeth to allow the rear piston to contact the intake valves. On disassembly I did not notice that the timing chain was particularly slack, but neither  was I looking for such things. The ATV has been serviced by agents according to requirements, in fact it was serviced very recently, by accredited agents.
      Coincidently I met another 800 XT owner a couple of days ago who had had a similar incident a few years ago, which makes it likely that there are others out there who have had similar experiences. If there are I'd very much like to hear from you.

      I have a 2005 Honda 300EX that won't start. I've changed the starter and I've changed the solenoid. When I try to push start it the back wheels skid, it's a manual. I've charged the battery and I've done the screwdriver trick with the solenoid that won't start it. It tries to crank but it won't turn over.  
      I was out riding for about an hour or two and then it quit on me. Before I went riding I change the air filter and I change the oil. 
      Heeeeelp. Suggestions? I'm learning all of this info myself from forums. Thanks.
