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.

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!

I have a Yamaha Timberwolf 4x4 250. I want to put a winch on it, but just wondering if the charging system will handle it or not ? Has anyone added one to their machine and have you had any issues?

I'm trying to help a buddy out with his bike (he's not really on the internet or familiar with these forums) and I'll admit that I am not super familiar with the transmission and clutches in these bikes. I owned a Brute a few years ago, but never had an issue like this that I had to troubleshoot.
So basically my buddy bought a group lot of 650's to build one good bike out of. He got it all put together and has it running but when he pushes on the throttle the clutch doesn't engage till the RPM's are quite high and even when its moving it doesn't really speed up, almost seems like its in "limp mode". He's tried 2 different transmissions so I don't think that's the problem.
Is there any adjustment on the clutch engagement? Anything else I can tell him to look at? Let me know if you need anymore information if you think you can help.

So we are almost a month into winter and I've been so busy working on my house that up until today, I didn't realize that we just haven;t gotten any real snow yet to warrant putting the plow on my grizzly. So that got me thinking, what are the latest plows out there and what ATV plows are the best? I've got 2 snow plows for my grizzly, a quadboss pile driver atv plow set up and a snowsport ATV plow. They are both a bit dated now and I tend to stick with the snowsport due to ease of use and I just like it so much. So if you have a plow on your ATV, please let us know what it is and post a picture with your atv/plow would be awesome. Would also like to know what you like and dislike about it.
This is back a while when I did a write up on these 2 plows.... in 2009 I got the snowsport and in 2012 I got the quadboss.
