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
Unfortunately I didn't notice some of the rust hitting the undercarriage of my 2004 Yamaha Grizzly 660, but saw it the other day when I was doing some maintenance, oil change, air filter, spark plug, etc. The left side footrest broke and that's causing the plastic to hit the front wheel. It broke right at the welds from too much rust. Looks to me like what I need is (looked this up on yamahapartshouse.com):
YAMAHA FOOTREST BOARD 5KM-27481-10 Left side (broken)
YAMAHA FOOTREST BOARD 5KM-27488-10-00 Right side (rusted and will probably break eventually)
Does anyone have a less expensive source? I did see on ebay a couple of listings but it still comes out to @ $50 each,

It’s kind of ATV related question as I need new trailer tires to tow my 4 wheeler.
Does anybody have any experience with loadstar 12” trailer tires ?
There is not to many choices for trailer tires here in Ontario and I was wandering if somebody can recommend me something.

I have a 2003 Kodiak 450 that i purchased a while back with around 300 hours on it. It has never ran right from the beginning. Initially i thought it was just a carburetor issue because it was all clogged up from sitting for months. It has been cleaned, rebuilt, and taken off probably about 10 times troubleshooting this problem. I have quadruple checked everything including float height ect and it is set correctly, the jets are also brand new, needle and seat have been pressure tested as well. So after all of that I am convinced that the carburetor is not the culprit. I have an issue where the idle is very choppy, almost as if it is misfiring with a rich condition on top of that. I can use a brand new plug and run the machine for just a few minutes and it will be a dry and and coated in black carbon build up. The exhaust also has a strong smell at idle. I had trouble restarting it when hot for a while, but i adjusted the valves and it seemed to solve that issue. They were both way out of tolerance (tight). The weird thing is, outside of idle it seems to run pretty well.
So with all that being said I have ruled out the carb/valves/compression and moved on to the ignition and this is where i have a few questions about factory specifications. I guess the main question I have is, how strict are these tolerances? And could them being off by this amount cause the issue I am having? Do all three of these parts really need to be replaced? I would like to know before I spend the money on these new parts, and it not fix my problem. Below I will list what the specs were in the service manual along with the reading i got. This is my first experience testing ignition components. I just found it odd that all 3 are out of spec according to the service manual.
Spark plug cap resistance: 10 kΩ at 20 °C (68 °F)
My Reading: 8.90 kΩ
Primary coil resistance: 0.18 ~ 0.28 Ω at 20 °C (68 °F)
My Reading: Fluctuated between 0.4 - 0.5 Ω
Secondary coil resistance: 6.32 ~ 9.48 kΩ at 20 °C (68 °F)
Reading was within the specified range.
Pickup coil resistance: 459 ~ 561 Ω at 20 °C (68 °F)
Reading was within specified range.
Rotor rotation direction sensing coil resistance: 0.085 ~ 0.105 Ω at 20 °C (68 °F)
My reading was 0.3 Ω
