Im new to the group and hope to find some help here. I have a 1997 Yamaha Big Bear 4x4. I am having ignition issues. I have checked all switches to the CDI box and all check out. I Replaced The pick up coil and stator, as the pick up coil was open, no continuity. My problem is I can't find a schematic that matches what I have. My CDI has 2 plugs one 4 pin with 3 wires going to it, and the other is an 8 pin with 7wires going to it. I have traced all but one it is solid blue on the 8 pin plug. I have no idea where it disappears to with out tearing apart the harness. Any ideas as to what this wire goes to? A pin out of the cdi would be helpful, The number on it is F8T32372. Any other ideas before I try and find a new CDI. Thanks for any help. Robert

Hi, Did you still need help with your Big Bear?  Sorry to hear about your ignition problems.  Did you download the service manual for your machine?  Not sure of your engine size, this might help:

You'll need 10 posts on here before you can download, I might be able to help with that if needed.....:o)

Let me know if I can further assist - Cheers!~  Bellarmine

Have a look here and see if you can identify your model..  Partzilla will tell you what any part you choose will also fit.. Look the part up, choose the part like you are going to buy it, and they will take you to a new page where it tells you what other models that wiring fits. If your wiring fits some other model, then the other model wiring will fit your bike. You can check their opinion by doing the same process in the other site.

      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.

      I am new to this site. I have a 1987 Suzuki LT230S Quadsport I think. Is there a difference between quadsport and quadrunner?

      1st problem, Does anyone know where I can find a stock carb for my Timberwolf, I have tried two different aftermarket carbs and they both suck. The machine runs great until it gets good and warm, then it keeps stalling unless I feather the throttle. it will even stall while I'm trying to go from 1st to reverse or vise versa. I took it to a buddy of mine who is a bike mechanic for years, and he told me try to find a factory carb. When I look online from dealers it says "NOT AVAILABLE" anyone have any suggestions ?
       
      2nd, The small tab on the rear axle for towing is to short for even pulling my small yard trailer, I can't even turn a little bit and hit hits. I tried making an extension which worked great as far as length, but it bends the tab and then the extension drags the ground. I have an idea of what to do to fix it, but wanted to see if anyone else has had this problem and see how you solved it.

      First thanks for any help guys, new to the forums and it's gotten me this far. I bought a 2001 bear tracker 250 for my family to get around the dirt bikes races. It wasn't running right and had a high idle. Previous owner thought it was a carb problem, so he ordered a new Zoom carb and new intake boot, but it still had the same high idle. ( I believe he had the throttle cable adjusted wrong, because it idled fine when I put it back together) So I tore down and cleaned the stock carb, and it started up and idled fine, but needed to have the choke 1/2 out to run.  I swapped to the new zoom carb and had the same issue. Choke half out bike ran ok. I played with the needle and the pilot screw with no change. ( bike did seem to be running rich though, but didn't get better when I tightened pilot screw or raised meddle) I Took it to the races and once I started bouncing around in the cattle fields the quad started cutting out real bad. It would barely run.  Sometimes it would run with choke off, sometimes choke 1/2, sometime choke full. I cleaned carb again, checked float level, and boots, no change still wouldn't run. Then suddenly it started running ok again.  This makes me believe it's an electrical issue rather then carb. I know there's no air leak, it's been checked, both carbs are clean( I've swapped them out a couple times, it starts up immediately and usually idles fine. But then bogs down/ or stutters under throttle. I saw the post on the guy who disconnected his rectifier and reconnected and suddenly it started working again, which lead me to believe it may be electrical and not carb.  So any advice on what I should check? Any way to test the CDI or rectifier?  Once again, I appreciate your help.
