You need to check the 5 code first. Code 1 means the ECU is crook (or got bad wires), but you fix what flashes on the dash first, then clear the codes and drive it to see what comes up next. The codes you have to extract, they are old and could be historic and irrelevant. That's why you clear them after you've done the work and re drive to see what gets set next. The recorded codes are good for finding intermittent faults. You just need the faults that show on the dash when you turn the key at the moment.

With trouble codes, we should never take them literally, they are only a guide.

The 5 when you turn it on is just a guide to what section of the wiring the fault lays in, it doesn't mean the motor or the motor drive circuit board is faulty.. Mostly it's wires that break. Here's the section out of the manual, and you need to start at page 22-12, and follow the instructions for checking the motor control circuit. The procedure starts at the bottom of page 22-12, and goes through to near the bottom of page 22-13. There are six steps of checking with a digital gauge.

Then you clear the codes (step four), and go for a drive. If the dash starts flashing after the drive and a re-turn on, then you fix that code next.

Thanks for the encouragement. I decided to just buy the ECM bypass shift kit. For only $20 it was worth trying. It will retain the push button shifting and the only down side seems to be harsh shifting if you don't come completely off the throttle. Plastics have been cleaned, racks sanded and painted, all the lights working, and a new seat cover. It was missing the fuel tank and used ones are $200, which is what I paid for the quad. So I just installed a little one I had from a 110cc chinese machine. I will probably end up selling this as a running parts machine or someone could pop for some new front palstics and a fuel tank and have a decent Rancher. 

Question: Why would the speedometer show MPH going up while revving in neutral? I thought the speedo was tied to the speed sensor on the output shaft?

Oh ok.. I couldn't make out what was happening in the video..haha.

Well done then. And the kit disables the dash flashing does it ?

How much did the speedo go up by ?

Vibration maybe ?

      Pulled my '86 Moto4 out of shed where it sat for 20 years. I knew it smoked. checked it over a little put in gas and it fired right up!! 
      Drove about 100 yards, ran about half throttle wouldn't idle.  Put on somenew parts, jug/piston and rings, carb and valve seals.
      'went together ok, tuned it over by hand about 6 revs whick went well. Hit the starter it fired for about 6 revs and quit. tried it again fired once and then th sound of something slipping like maybe chain slipping over spoket.
      Took cover off to watch cam sproket, hit starter again, heard same noise and the cam sproket was not turning but jumping a bit. Chain was still tight. You will probably tell me I need to split the lower case but hoping there mightbe something else.
      I don't fully understand the chain tightener, the plunger only moves about 1/4 inch, should it move much more than that when off the motor and compressing it by hand?
      Thanks for any thoughts.

      I was given a quad 4 years ago. Before that it was sitting at the edge of the woods for 17 years. I think it’s a 86 230 quad but that’s just a guess I have. Never had much dealings with a Suzuki mostly Honda atc’s and Kawasaki. Anyways. The bike was sitting at the edge of the woods with weeds growing through it. I couldn’t see the wheels, nor the rear diff. A family member who had bought it in the early 90’s had it and ask he if I wanted it. I said I’m not interested in buying in but if it’s free sure. Might have some use for some of the parts on day. Well I drug it out the woods with a tractor. None of the wheels turned. I loaded it up bright it home and dropped it beside my shed where it sat for the four years I had it. Until…. 2 weeks ago my wife said I needed to declutter. I thought to my self. Well I haven’t even glanced at it since I had it. So I might as well see if it’s worth fixing, sale it, or scrap it. I knew the wheels wouldn’t turn. I soaked the intire 4-wheeler in penetrate oil, resparying it every few hrs for the next few days, aired up the tyres, and keep rocking it back n forth until it started to roll. The key switch was all to pieces and their was no battery. So I tried to pull the recoil. Nothing. I removed the recoil. Soaked it in a tub of diesel got it working. I put a wrench on the crankshaft. It did not budge. Hmmmm no good. Well I guess  better check the oil. Even tho I know it’s locked up. I could see water in through the sight glass. I pulled the clutch cover off. Rust and water everywhere. Mmm mmm mmm my favorite cocktail. I sprayed it all down let it soak. Took all the clutches n things apart, cleaned all the rust off. Lubed it up and put back together. I thought to myself. It’s going to leak without a gasket and I’m not buying gaskets until I know it’s worth the money. So I put a small bead of rtv around the cover and let it cure before I reinstalled it. Tired my luck again a spinning the crank. No luck. I had a hunch before I began that the piston or crank was froze because the seat has always been laying on the front rack as long as I’ve known and the air box cover has been missing exposing the air filter not connected to the intake tube. I pulled the plug finally. lol. I sprayed 3 cans of brake clean in the jug and screwed the plug back on. I let it sit over night. The next morning I filled the cylinder up with deep creep. And let it sit and sit and sit. For a few hrs. I slowly pulled the recoil. It moved!!! I moved it maybe 3/8” and I stopped pulled oil drain bolt drained the oil and fill the cylinder up with a mix of penetrating oil and gun oil. And let is sit for again over night. Pulled the plug out. Pulled the recoil a few times. It moved nicely no sounds of anything scratching rings and no hard spot while pulling. Next, I hooked up my spark tester. It was firing great. Nice fat white/blue spark. Now time for the carb. I unscrewed the throttle valve cap and the throttle valve was stuck. I unscrewed the choke nut and the choke plunger was stuck… I I sprayed it down with brake cleaner and penetrate oil. Screwed the cap back down and the choke nut and I let it sit again over night. Next day they came out like they should. So then I removed the carb. I could see the ethanol cancer before I even tried to remove the carb bowel. I put it in a coffee can of diesel fuel. After sitting I removed the fuel bowel. Here’s a tip I’ve learn on bowel screws a while back. Clamp the carb in a vice with a thin block of wood covering the jaws of the vice. Take a punch same size as the screws. Maybe slightly larger. And rap the punch with a hammer a few times. Not to hard lol. Works great on brake reservoir bolts. Never stripped nor broke one doing it like this. I got the bowel off. Their was so much dry crude I could not see the starter jet. I cleaned it without removing the jets. I took my Tourch tip cleaners and brake cleaner finally got the wire to push through the main jet and starter jet. I put the bowel back on. Put a fuel line on the carb and a small lawn tractor fuel tank full of fresh fuel. I turned the carb every way I could. Couldn’t get fuel… took the carb back apart except for the main jet, starter jet, or the mixture screw, and low idle screw. I let it soak. Could it blow threw the fuel inlet tube. I tried inserting the tip cleaner. No luck.. I took a old cloth hanger, cut it 2 1/2” long and ground it down to about have it’s dia. Then I drove it trough the carb with a hammer. It cleared the way. I put the carb back on the engine and hooked it all up except for the vent hose. Drained the crank and filled it with rotella 15w-40. Put in a new plug dipped in fuel. I pulled on the recoil and it started and idled on the second pull. I let it run for a minute or two. Drained the oil and refilled it. It started back up. I started driving it around and after around 5 mins I had to stop. I was out of oil. Major oil leak. Time to strip it down clean it up and start bringing her to life. I knew I could make it run again but never dreamed it would sound as good as it did. Let alone as cheap as I did. Brake clean and oil free from work. lol. Rtv $3.58. Fuel…$3.19 a gallon. The oil leak is a busted oil drain bolt cap cover. I’m also missing the box box lid. It would sure be a lot easier if I knew what kind of machine I have. I knew but not not know. I know years ago when the family member bought the bike a few months later it was stolen and returned with all the stickers peeled off and the wheels painted black. Who ever stole it also wrecked and bent the front rack and left Handel bar. I did not know until now that they removed all the serial numbers… stamped on the lower part of the cylinder jug is 229. That’s why I believe it’s a 230. And it resembles a quadrunner. It’s 2wd with reverse and hi/low. Shaft driven. I will upload pictures and a video. If anyone what’s to share any wisdom on this ol girl feel free. I like to know what it is and I appreciate any knowledge your willing to share.

      Okay, so I have a 2002 Rubicon 500…bought it last year and it sat for several months until I put a new rear axle in, FINALLY got that done and was super excited to finally have my wheeler going, just to notice a strong gas odor. Popped the seat off and sure enough, pouring gas from the carb overflow. Fast forward a few more weeks and get the new carb and get it in, no leak! Yay. Except now I have no spark. 😒 I’ve tried another plug and checked and am getting no power to the coil pack. I’ve read and read and mostly what I’ve found is ECU, which is fine…but I like to exhaust all avenues before buying the more expensive parts just because I don’t wanna spend the money and it have ended up being something simple that I overlooked because I was trying to rush. 😂 I don’t know if it’s relevant, but I read on another post that someone had similar issues with theirs and it was the sensor on the side of the carb, just a thought since this literally happened after I put the new carb on. It also displays “- -“ on the display screen where it should show the gear position.
