I am looking to see why my 2005 Grizzly 660 won't crank. I have set the valves but suspect a loose timing chain.
When working to remove the valve cover I found a "cap tensioner case" - parts #25 - #299 on Babbitts site.
The cover seems to bridge the valve cover and the cylinder head. What the hell is it and what surprises will I find if I remove it?
Uncharted territory for me.

So I have my very first Atc still. My dad gave it to me when I was very little (was brand new; one owner bike), and it has needed just two repairs over the approximately three decades: replace/repair pull-start.
Any ideas of some simple & not so simple mods/upgrades for this classic? I'd LOVE to swap the tranny for one with a real clutch, personally...possible??
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

Our 1988 Yamaha Terra Pro is finally seeing the finish line of becoming our new bush hogging tractor! I've had the terra pro for almost 2 years... we had great intentions, but after removing the fenders, fuel tank, and the carb, we let it sit up. Shame on us! However, the terra pro is cranking today. We cleaned the carb, figured out what goes where and where did that screw go! She smokes like there's no tomorrow, but that's okay! The only issue right now is getting all these lines hooked back up to the carb right! There is 5 lines to hook up to this thing!! And in our moment of drinking and removing parts, we cant remember how they go back on. I've found several diagrams online, but none showing the overall schematics of all the lines! If anyone has a service manual, or any way of helping us figure out what goes where I would really appreciate it!! I can attach pictures later if it'll help!

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.
