I have a 2004 Yamaha Bear Tracker in the shop for repair. I have the service manual but it doesn't have all the information I need to fix the problem. I need to know the voltage output of the stator charge coil and pulse or trigger coil at cranking speed. The wiring diagram color code doesn't seem to match and that is compounded by the fact that the wiring harness CDI connector is missing so I have 7 wires that need to be connected to the CDI. I can not find a circuit diagram of the CDI which tells me where the pulse/trigger coil connects or the charge coil connects. The other 3 wires (black ground, orange ignition coil, and r/b ignition kill sw) also need to be connected. The CDI has a single 8 pin connector and has a P/N 4XE-00 F8T19871 -1122 number on it and I believe it to be OEM. However I think the Stator and pulse coil are aftermarket items. I have resistance tested everything and it all seems to be in spec. but I don't want to miss wire anything and cause damage. Any help would be greatly appreciated.

I need to figure out how to clean/fix or replace my neutral switch assembly On my 2008 Yamaha big bear 400 as generally the neutral light doesn’t come on when it is in neutral. To get it to come on I have to wiggle the foot shifter and hold it in just the right spot.
I have googled it and can’t find much on the 400’s. I can’t find a service manual online and the parts manual is super vague.
I think it is in the right side engine cover area, but not certain.
Any help would be great. thanks

posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
Want to show you one automotive show that I filmed in my town called Crazy Race. This was two day race in Qualifications round, Semifinals and Final. In this 4 parts I am showing best moments from all rounds and entertainment of the show.
Crazy Race Part 2 contains a qualifying round where all riders race against each other, selected by lot and split by two. They are free to drive in any direction and to hit their opponent's car everywhere except at the driver's door. Anyone who intentionally hit the other car in the driver's door is disqualified. Winner of each race continue in the semifinal round. In this part I will present the best moments of the qualifying round!
Part 3 shows you the best moments from Day 2 - Semifinals and Final. Battles in the semifinals are among the winners of the first day races, but this time they are selected by lot and divided into 4 battles of 4-5 cars each. The rules in each battle are that they only have to drive in one direction and try to neutralize other opponents until there are only two players left. Then the battle between the two last drivers has the rule to drive in any direction until only one who has qualified for the final round is left. Again, anyone who intentionally hit the other car in the driver's door is disqualified.
For the final round there were only two cars left, because the other two players who got the right to be there had problems with their car and could not participate.
Part 4 containing entertainments between battles and winners rewarding.
This event will have second round in 05-06 October 2019 and also will be filmed For this new round I will filmed in many new angels and places. Will prepare a lot more videos and many new entertainments . This 4 videos was my first try so many things to wish for better filming in the future one.
Hope you will like them and of course feel free to comment and to ask everything. Hope you will Subscribe to my channel and to be first to see my other content and of course new round of Crazy Race! Thanks!

Rescued this thing from sitting in a warehouse the last two decades. Finally got it to fire, but when I put it into neutral to do so its now stuck in neutral, and wont shift no matter how much pushing, rocking, etc. Even with throttle it wont. Range lever on left side will go from H to L, but not to R, and this makes no difference on it being stuck in neutral.

I got this almost a year ago for $500.00 it was covered in a garage and owned by a 57 year old lady. She said she didn't need it anymore and wanted me to have it for my kids 1 of which is level 3 autistic. Ritual oil changes and yearly service. This was barely driven and when it was it wasn't beat on. All in all I got a killer deal on this wheeler and nothing is wrong with it. Starts and drives like its brand new.
Hey guys I have a Yamaha moto 4 250 that was running great now all of a sudden I have low power. It starts up and idles great and engine sounds fine no knocking or ticking or anything like that. I can ride it and sometimes its like you flicked a switch and the power comes back for a minute and then it goes away again. I've changed the spark plug, cleaned the carb and it made no difference. I'm thinking the stator could be going bad but id like to find out more before I spend the money on it.

I have 2 1985 Yamaha yfm 200s the yellow bike runs great plug is nice and brown nothing worng with it the black one however runs like a bag of ass it Spitz out the carb it sputters runs real hot it's lean I know that but it literally has the identical carburetor every part of them is identical inside and out and no matter what I down I can't get it to richen out rather burn a whole lot of gas then burn the piston
Just purchased one of these and I have a few questions: Went to change the air filter and it fell apart, but there were two pieces of the foam wrapping the wire cage - Normal? In addition there was about an inch of oil in the bottom of the air filter box - again - Normal? The backing piece of plastic for the wire cage was laying in the bottom of the filter box and the bolt was also in the oil. I am also looking for a recommendation on what to do with the machine as far as maintenance, it runs well, shifts fine, needs a new battery, but what else should I be checking? The previous owner had it for over 25 years and does not have any records or memory of the last oil change or any other maintenance other than needing to replace the battery a couple of years ago and placing a car battery on the front rack and running wires to the starter. Learning curve is sharp, but looking forward to the experience. Thanks for your input.
