Is there any special way to align the front end so that it drives straight?
It's not bad, but it still could use an adjustment. I'm suspecting the tie rod was improperly adjusted to compensate for the bent lower "A" arm which i replaced.

Still working on the 2000 Big Bear with a no spark issue. A lot of this has been covered in an older thread, but I will summarize.
Bought it with the previous owner telling me it needed a new wiring harness, but the wiring harness was in tact and seemed to be fine, except starter solenoid and coil was missing, also the engine was stuck, and no spark plug. Got the engine free and rotating, checked compression, it was 130, not great, but good enough to run. Hooked up a battery, nothing , went through all the wiring and found starter cutout relay bad, replaced that, now I have it rotating with starter. Pulled the plug checked, no spark. Checked start/stop switch, working like it should, reverse relay was bad ,replaced that. Checked continuity from coil to CDI, good, checked pickup coil resistance, within specs, checked anti kickback coil resistance, within specs. What am I missing.

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

Hello I am new to this forum and I just had Big Bear 400 given to me for free. I am in the process of tear down to begin rebuild. I have 75% of the parts to be in rebuild but what I am lacking is a good manual. I have the Haynes manual but it appears to be very generic. I am in need of a real good manual with plenty of details. Can anyone help??
Thanks much

Finally getting around to the Yamaha Big Bear that followed me home in August. It is a mess. I got it off of marketplace, the add stated " runs like nothing is wrong the only thing that's wrong is it needs a new wiring harness". So iv been looking for a new wiring harness although it came with a wiring harness that was out of the bike, so I assumed he had ripped it out. All the plastics were off and no screws or bolts to reinstall but they were in good shape. The coil, voltage regulator and starter solenoid was missing but came with new one. So I go out expecting to start installing the wiring harness and find out its still in tact with these parts missing. The first thing I found was the engine was stuck and there was no spark plug in it. I noticed when I bought it that the pull starter wouldn't rotate the engine but he assured me the engine wasn't stuck that there was something wrong with the pull starter, I was skeptical but took him at his word. I didn't check it that closely because I was really just buying it for the tires and wheels they were worth twice what I paid for the bike. Im a little new at buying on marketplace and am just angry that someone would lie like that, now I don't know if anything is really wrong with the wiring harness, im probably too trusting I usually trust people until they give me a reason not too. I would have bought it anyway, if I go to the trouble of hooking up my trailer and wench and driving there its coming home with me, long as its a Honda or Yamaha I can fix it. It took PB Blaster about 24 hr and I got the engine freed up, and it has good compression, using ye ole thumb over the hole test, and the pull starter works fine Thats enough of that, now for my real question, before I go to the trouble of chasing the wiring problem down I would like to see if the engine is ok , is there anyway to feed voltage directly into the cdi to make it spark.
