1989 Moto 4 YFM350ERW intermittent spark.
Quad has set for about 7 years and was running when parked. When I replaced the battery and attempted to start it had no spark.
What I have done. Followed troubleshooting in the manual.
1. Coil failed the resistance check so I replaced it. Still no spark.
2. I performed resistance checks on the stator and they all pass.
3. Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable. Now I have intermittent spark. I believe that the issue is with either the stator or CDI and not sure which.
1989 seems to be a transition year for electrical. I can get new aftermarket CDI units for 87-88 and 90-94. I cannot get ones for a 89. I can get new stators for 87-89 and 90-95. Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI. Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available. Does anyone know if this has been tried before and if there are any issues with doing this.
As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time. By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.

Hi, I have been around everything with a motor since I was little, and finally purchased more to get my husband, and kids involved. I have 4 quads I will be searching around for information on. I have two 2002 Suzuki LT80K quads, a 1997 Yamaha Timberwolf 250, and a 1996 Kawasaki Bayou 220. I have had different ones throughout the years, and plan on buying another Yamaha Banshee. I plan on trying to learn more about all of them, so I can customize some of them. I know nothing about them besides how to race them, my dad always took care of the rest, but figured it was time for me to learn.

Hello All
I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area.
Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.
