got 7 atvs off CL recently for a good price. one of which is a yamaha warrior. anyone know where the vin is printed on this bike? Haha good place to start as I do not know year or size yet. The former owner says needs exhaust ans and clutch work. he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears. things I see: clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box. I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first. also, battery (looks brand new, what a shame) is dead, 0 volts. Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last). any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like. lol I'm spoiled on my automatic polaris
My lakota has a new carb and just had a top end redone by a professional, but it will not start. The electric start turns it over great, there seems to be compression. It seems like its trying to start, getting right there and just doesnt catch. It does start occasionally, but wont run for more than a couple of minutes and smells rich. Im assuming the carb needs to be tuned, but im just wondering if anyone else has any ideas before i get a chance to work on it.

I picked up this quad after the previous owner couldn't get it going.
The issue is that I can't get it to fire at idle or at all.
- replaced plug. Decent blue spark. Also tested with spark tester inline.
- rebuilt the carb. PO had already bypassed vacuum lines from petcock. There's fuel at the cylinder
- Checked compression with new gauge. reads 190 psi
- cleaned all contacts I could access.
- am currently jumping with car battery. Solenoid jumpered.
- checked cam timing at TDC and adjusted valve lash
- put gas directly into cylinder to see if it will fire at least momentarily
Motor turns over well. Plug gets wet.
Motor may fire once or twice but smokes through exhaust a bit as if it's trying to fire or combusting.
This leads me to suspect timing. As mentioned I checked the flywheel mark versus cam marks. Perhaps someone has been in there before because I can't find a 'T' on the flywheel but there is a very visible paint mark which aligns with TDC position on piston. Possibly a slipped flywheel/woodruff?
Is it possible that if it had seen previous repairs, that the timing could still be off? I'm reluctant to dig into the flywheel/stator area if there's something else I could have missed but all signs point me to that area. Would a bad CDI cause spark timing to be off?
Anywhere else to diagnose incorrect spark timing?
I've scoured these forums and elsewhere but I'm posting just in case there's something I've overlooked up until now.
Thanks very much for reading!

I am goin nuts here! I have a 04 400 air cooled 4x4 , I'm a atv,car,truck,mower mechanic for yrs,just sayin. Ok it cranks and kinda fires now and again then after 5 min of cranking and stopping itl start if u touch throttle itl did then u start all over! If u let it warm up sumtimes u can throttle it up other times it just does! Just depends on it? When it stays running it runs awesome,no problems except it just does randomly like u shut key off? Sumtimes itl start right back up others itl do the no start thing! IV put new plug,adjusted valves and hot tanked carb? I'm at a loss here guys! Please any other ideas? I don't think it's anything to do with flywheel? It's not the auto it has a hi low reverse lever on left fender and foot shifter? Help please lol

The short of it: I'm getting a single click when I hit the start, and nothing else.
The long: I'm a new owner to a 94 Timberwolf. I inherited it with the understanding that it needed a battery. It started without the battery when jumped, so I know it does work. I got the appropriate battery, charged it, and its reading 12.7V. Installed it, and all I'm getting is that click. Cleaned the carburetor today and reinstalled under someones advice, but still nothing. I'm gonna take the battery in to autozone to get it checked, and I was going to head to the spark plug next. But like I say, I'm new to this. Thanks for any and all advice.

Yamaha Grizzly 700 gets STUCK in Pond Huge thanks for https://myneighbourhoodnl.com/ for the rags we mentioned in the start of the video! we will definitely put them to good use! A few close calls in this video thats for sure! thought I sunk the ol grizzly for a split second... Gotta love Yamaha with their single cylinders. I really think its time for them to come out with a twin now! But gotta stay true to the Yamaha grizzly 700s! This was a really cool run that we happen to go on. no route for the yamaha grizzlys 700. Just picked away finding spots we never went before really. Make sure to follow the yamaha grizzly 700 on instagram! instagram.com/offroad.dan instagram.com/muddymillz
This was probably the roughest ride we went on to date, I know in the video it doesn't really show how rough the ride actually was but boy the Yamaha grizzlys 700 definitely never enjoyed that run at all the silverbacks and Yamaha grizzlys are definitely not built to go rock climbing like we just did in this video. But that being said this run was a good one and Jon only broke 1 shock on his Yamaha grizzly 700 Follow us on instagram: instagram.com/Offroad.dan instagram.com/muddymillz
