So I’ve had this bike for 3 years now. Love it. But there’s one question I never got an answer to. And maybe by now somebody’s figured it out...
The instrument cluster has 5 screens... Odometer, Trip, tach, battery voltage, and a screen that says “L 16H 8”. Does anyone know what the shit this means? See pic.
It’s never changed. And those aren’t words. Hahah

Following on from the brief interlude in the "introducing myself" thread....
In a nutshell, I acquired a YFM250 Moto 4 (1991) for cheap recently with the previous owner citing "no spark, needs a new magneto coil and I don't have time to fix it"... anyway I am dubious that the magneto/generator is the issue and thinking more along the line of ignition coil as after a clean up of the magneto I was able to get a rather decent voltage reading off the magneto with pull start and resistence readings seem to check out that the magneto is all ok (all 3 x phases = 1.2 ohms and no run to ground)
None the less I ordered a new Ignition coil and Magneto/generator coil and am waiting for them to arrive.
In the mean time I cleaned up the current Magneto, popped in a new battery and sparkplug, checked out all the wiring harness, all seemed good except I came across the "neutral switch" wire was broken.
After wiring up a new neutral switch wire, the neutral light now comes on (small win) and the starter relay (attached to rectifier) now clicks. If I hit the starter switch on handle bar the starter motor spins and if I pull the cord starter I get a spark on pull....YAY!! I'll try and attach a video below if possible.
So onto the starter motor. Starter solenoid seems to work A-ok, even if it looks crappy and starter motor spins as it should when I hit the start switch....but here is my issue.
When the starter motor runs it turns Cog #1 and Cog #2 (see photo below)....but the chain in the back of the starter which I assume is the timing chain, does not move and there is no apparent movement of the piston in the cylinder.
If I turn it by hand (per photo) or with the pull starter however the chain moves and the engine turns. However cog #2 rotates but not fluidly with the "Crank" (part I turn by hand) for the lack of a better word to use if that makes sense?
Is there a grub screw or similar on Cog #2 that fixes it to the center shaft to make it all turn when the starter motor is run? Could there be a part missing? Previous owner had the starter apart so could be possible?
The outer/front part seems to be on a key-way so not sure how to remove this easily to check how Cog #2 is attached.
What am I missing here?
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.

New arctic cat owner, I've read alot on the gauge issues, but let me say I have power, good ground, the aux also has power, the memory has correct voltage but no output of any kind. Only the LCD color works. I have also fully removed EVERYTHING and cleaned it all... what I still possibly have a cut wire knowing that I have good power to the back of the plug and good ground to the back of the plug but no outputs of any kind?

I have 88 4trax FW , it has a booster circuit
In the cdi control fed from a leg in the alternator.
MY Honda service manual says you will get no spark without this circuit on this model.
Can someone explain a little about this please ? Thanks
Rescued this thing from sitting in a warehouse the last two decades. Finally got it to fire, but when I put it into neutral to do so its now stuck in neutral, and wont shift no matter how much pushing, rocking, etc. Even with throttle it wont. Range lever on left side will go from H to L, but not to R, and this makes no difference on it being stuck in neutral.
Have a 2000 Yamaha Grizzly YFM600FWA with no spark. Checked the troubleshooting chart, and all checks were within specs. CDI has part # 5GT-00 F8T36071. Friend has a 1998 Grizzly 600 but his CDI part # is 4WV-00 F8t34671. Are they the same? Thinking about taking my CDI and put it on his ATV and find out if it works, but don't want to damage something if not interchangeable. Thanks
