1989 Moto 4 YFM350ERW intermittent spark.
Ha.. That is a bummer.. That it's started to work ! I hate that too, all the more since I'm a mechanic. Perhaps now leave it idling and wriggle all the wires everywhere bit by bit hoping to find a short or broken wire that makes the motor die.. Wires mostly only break right where they go into the metal crimped terminal, and they break inside their insulation so you need to use long nosed pliers to gently tug on those ones, and the other place that used to be more common in the past when they used thick wires, was up near the steering head where they flex. Shorts to the frame of course.. anywhere. I'd also check the switches.. The kill in particular is prone to dirty or mud filled contacts. The mud not actually being a dirty contact problem, but when it gets wet it can short enough to cause problems. And thanks for the thanks. It's my pleasure. -

1989 Moto 4 YFM350ERW intermittent spark.
Sorry for lack of response but have had little internet the last few days. I do want to thank you for all your help with this as I had a big learning curve. Not having good schematics didn't help either. It has started to work. I hate problems that just go away on their own. The fact that the pit bike CDI worked from the start leads me to believe that it is most likely one of the interlock inputs. I suspect that one of the interlock switches was flaky and when I checked it without any movement it would show good and when the motor was rotating it would come and go. If not that then a bad connection that when disconnected and reconnected. The fact that the pit bike CDI worked from the start leads me to believe that it is most likely one of the interlocks. I have not tested it by riding it as I want to go through the brakes and make sure they work good before I do as it has set so long. Stopping is always a good thing. Luckly this ATV will mostly be used on my property in Idaho and not on trails so when (not if) this problem appears again I won't be in some remote location. I also plan to take the older CDI that I purchased and that didn't work and cut the connectors off and wire up the pit bike one to have as an emergency spare. This will disable all the interlocks but should allow me to get it back to the garage easily. -

Bikes of a certain design get released on different continents in different years, and in any particular year they release different version/spec bikes into different markets as well. Also, in motor vehicles at least, and it may not apply to quads so much, countries have trade deals in which a country will assemble vehicles but as part of the trade deal they want to use some local content, so the country supplies some components they can manufacture in their own country.. So wiring looms, seats or upholstery, starters or generators, paint jobs, carpets.. Stuff like that used to be local sometimes. When we are looking at the service manuals, we need to be sure they do apply to our market or the market the bike was intended for.. before it got re-routed to a different market.. haha. And, Yamaha are the very worst for swapping their electrics around I think anyway, without any of those market changes !.. -

A little more information: I have to admit it, from a marketing standpoint alone, calling so many machines the LT230 wasn’t the best move on Suzuki’s behalf. There were some years when they offered a whopping 6-machine variant on the line at once with the letter designations at the end being the only way to identify one from the next. There’s good news though- the letters tell the story. First the LT230 portion tells us right away that it uses Suzuki’s overhead cam 2-valve 229 cc (“230”) 4-stroke single-cylinder engine. Next the vehicle name tells us about the transmission. Suzuki used the designation “Quadsport” to identify machines boasting a manual clutch transmission (an S letter designation) and “Quadrunner” to describe those machines with automatic clutches. When an E appeared at the end of the vehicle code, that meant the machine came equipped with electric starting (the pure S version was kick start). Lastly the G series meant shaft final drive (as opposed to chain).- 1
