I lost the washer for this and have one in there atm but just for peace of mind I want to buy the oem washer I need help on the name of the small gear on my 2006 raptor 350

the cam gear and cam is no longer attached the shear pen broke it was a pos make sure kids to buy oem

so I bought this raptor from my bubby because it sat in his garage for a year or suck long story short the guy who lost worked on it didn't know what he was doing can just did some of the worst work I've ever laid my eyes on but I recently had the thing running and delt with a lot of problems getting the damn thing to spark need new stator/ cdi and wiring harness and I had finally got the thing to run and drive had a blast omg I love this thing but sometimes I pray it would just stop giving me problems I've road the quad 2-3 time and found there was a huge leak and I took the head off its new btw its black and shiny but the last guy who worked on it did a horrible job and lost parts any ways I fix his mistake and bought oem parts and gaskets but when I when to put the piston back in I could not find a good thread on the orientation on all the rings on the piston and it is a bit confusing how people describe each ring I need a layman's terms like talk to me like I'm slow lol but don't be rude and I need help 1 in the orientation on all the rings and also my engine stopped sucking threw the carb can it be the valve is not seated on intake/exhaust should I reopen the head and redo the rings on the piston or can it be the valve spring gap idk I need help all I know right know is I need a break from the bike and collect information for now can I get some help without people pointing me in all kinds of direction

So in my conclusion if you have no spark 1 Check wires and ground if bad clean connections/ if good go to 2 2 Check sparkplug if bad clean or buy new spark plug / if good go to 3 3 Unplug voltage regulator and turn the stator on and turn over engine 1 spark go to 4 /no spark go to 5 4 check resistance on stator "circular copper windings looks kinda like alternator" and pickup coil "small magnetic box next to stator" both on the left side of the engine in side engine cover/ if good go to 5 5 Replace CDI CDI was in fact the problem

Update I tested the ignition coil I got very werid ohms and I tested the orange wire and I believe I had gotten 24v or something like that going to the orange wire right before ignition coil as you know the plug its self was getting nothing no spark even when taking boot of I've read if you unplug the voltage regulator than if you get 1 spark out of the ignition coil than is 9 times out of 10 the stator and pickup coil so I had a feeling that it was the CDI/ECU I bought a cheap one off of Amazon and it ran me like $30-40 but and my gut feeling was right I really could not find ways to test the CDI but looking at schematic diagram it showed that it takes stator voltage runs it to CDI turns around and takes that voltage and runs it to the regulator and the regulator runs it right back to CDI and builds up voltage in a coil "ignition coil" and has a signal wire which is the black wire on the ignition coil and tells it when to spark "timing"

So from my understanding what makes the spark Coil =unknown Stator/pick up coil =good Cdi/ECU =unknown Sparkplug =good Battery/ I think it's good but it has 12.8 and I have charger soo =maybe good Regulator rectifier =unknown Wiring harness/connectors =good I don't see them cut in them or not messed up. =Maybe good Ground more than likely dirty =good? Kill switch =unknown

So update I've changed the stator and pickup coil today still not the problem high key upset but I'm waiting on my coil (comes tomorrow in the mail) which I've read is rarely the problem but easy change out if it's not the coil I'm going to disassemble my light/kill switch tomorrow I really scratching my head on why is it the fact that I had spark 1 day and the next when leaving battery on and cleaning the carburetor is that I have no spark 😤😒

I've tried that maybe I don't know what I'm doing 😅 but I bought a new pick up and stator also a new coil I'm going to change them individually and let you when I get it

I went to find my make and model I found a warrior 350"same motor" and 2004 Yamaha raptor 350 "service manual not there" Okay I read some more it says I can't download until 10 post wth is that pos

Okay so here's the deal I really need some help I got the quad from my buddy he had the head redone because of smoke it was either two things rings or valves so all that looks good I got the exhaust valve and intake valve to spec with the rocker arms then I had made sure cam was in TDC it lined up in spec then I was trying to start it up for the first day it started but ran like s*** then I had the next day recharge the battery and tried to start it again still run like s*** but I was just curious if it ran so I was thinking it was taking too long to start up so I clean carburetor today and retried to start it up and the only electrical part that was disconnected was the ground to the reverse gear controller so that I could take off the throttle then I pulled the spark plug out to check to see if I had spark the last 2 days I had spark cuz I pulled the spark plug out and seen it but today when I went to clean the carburetor out I accidentally left the battery on on all night and now I have no spark at all I pulled off the spark plug boot the screw thang and put my hand on the spark plug wire as I turned it over with the starter by the way the starter runs great now but zero electricity I'm just wondering how do I test my coil what is the resistance/ohm's it needs to be inspect I can't find it nowhere and how do I eliminate the fact if it's the stator somebody says something about a CDI and I seen a form saying if I unplug the voltage regulator your spark plug might spark again but I clean most of the connections I still have no spark
