Not sure, but I agree with Mech, must be different carb I don't have anything that looks like that on my Big Bear

OEM parts I use Rockymountainatvmc.com.

I have noticed that the CDI boxes for the older ones are dirt cheap, not so much on 2000 up models, one for mine is at 400.00.

Iv always been a little afraid of buying electronic components on Ebay , will they actually work and for how long.

Oh! the scissor table is much better, never got one because they take up a lot of room.

Is rather confusing because the Rotella is T4 and the Suzuki oil is 4T

Thanks a little behind on my abbreviations

Looks different from mine mine has a cap that covers the hole without the lock unlock mechanism I will take a closer look to see its all apart im chasing shorted electrics.

I have a 2000 the only hole I have on my fender is for an accessory power outlet my differential engage is on the handlebars but it doesn't look factory

I don't recognize the carb either the hose with a screw in it looks like s fuel hose the other look like vacuum hose and the symbols on the petcock are strange it looks like open and closed, but im sure you have already figured it out.

So it kinda runs I don't know what WOT means

Good you got it going, sounds good.

I know what you mean it doesn't take long to sink a lot of money into one. I try to look at it as, im fixing this up to use, maybe I have more in it than its worth, but its good and it will do what I want it to do and its cheaper than anew one.

With the crack that's good that you are replacing it would be hard to bend back exact.

Wow you have done a lot , it does seem like fuel delivery but you have changed all that, so your on the right track maybe CDI is not advancing timing enough to keep up.

Sometimes gas can leak past a worn float needle and seat you should replace it. I usually turn my gas off when not running and its going to be sitting for a while. I got used to doing that with my lawn tractors, briggs are notorious for that.

Ive noticed that also, the things have been abused so many years with little to no maintenance and just pieced back together when things don't work right. It will take a little patience to get it back right nickel and diming here and there but once you get it back right you will be proud and know it right. Then you can take care of it the way it should have been done from new. I don't know how bad you are bent but you may be able to take it out and. bend it back with heat. One of mine does not sit square either still trying to figure out why, it doesn't seem to be bent and does not cause any problems, but I don't like it, its like it needs an alignment.

OEM carb should say Mikuni on it aftermarket no writing at all , some oil may come out from the filter but always drain oil from drain plug on bottom of engine, choke plunger should just pull out of the carb if the threads on the plastic piece are stripped if not unscrew it mine are always stripped. Good job on hardwood floors. Thats next on my agenda. Oh, good job on the bearings ,they can be a bear sometimes.

If it has stopped working completely sounds like power is not getting to the unit I would start by checking to make sure you have power going in.

Sounds like a really nice machine I have looked at those at Lowes also , very impressive. You have done a great evaluation of it, thanks for the information.

Thanks guys for the quick response. Iv been checking the existing wiring harness and it seems to all be intact did not notice any problems except for the missing parts the coil that came with it looked like it had never been on a bike was bad, primary resistance was good no resistance whatsoever on the secondary even took the wire and cap off still nothing. The key is missing have to get a new switch and all the other parts I mentioned earlier. You are right Mech about the CDI it like the wire hub central all the wires go there with 3 big plugs. I was thinking the red and white was hot and I might be able to feed voltage there directly to see if it would spark but was not sure if it needed 12 volts there or lower, the service manual didn't really say or I missed it, it doesn't really tell you a check for CDI it has you run all these other tests and if they pass and still no spark replace the CDI. I think I will take your advise go ahead and hook everything else back up and then start looking for the problem.

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.

I haven't seen one of those in a long time, I think you guys are right on about the year. What I remember about them is they were a lot of fun to ride, small and light. Good job getting it running.

If your looking to buy used eBay, or marketplace, new I use motorsports.com or rockymountainatvmc.com for OEM parts.

Great tip, Ace hardware black pipe is one of my favorite tools.
