I have a 2007 kingquad 450 fuel injection. I try to start it with the hand crank and almost flip over the quad. I have taken the hand crank off and cleaned it but this did not fix the problem. I believe there is a decompression valve that is supposed to engage when pulling it over by hand. How can I check this?

I wanted to share a successful workaround for a "no-spark" issue on a 2009 LT-A400.
This is specifically for cases where the CDI has been diagnosed as faulty, but the age or condition of the machine makes the cost of a brand-new OEM unit hard to justify.
Note: This modification compromises the factory “no-start” circuits.
On some malfunctioning CDI units the internally damaged circuitry is only partial.
Feeding full time power to the Parking Brake pin, the unit is triggered to bypass the internal fault and produce a healthy consistent output to the Ignition coil.
The Modification
See the second diagram attached below for the wiring specifics.
The Result:
The machine has clocked over 1,000km since this repair and is still running strong with no ignition dropouts.
⚠️ IMPORTANT SAFETY WARNING ⚠️
Please be aware that this modification compromises the factory safety "no-start" circuits.
The machine will now start in gear. The safety interlock involving the handbrake is no longer functional. The machine can move unexpectedly if the starter is pressed while in gear. Proceed at your own risk. If you sell the machine or let others ride it, ensure they are fully aware that these factory safety buffers have been removed.

I have a Yamaha Timberwolf 4x4 250. I want to put a winch on it, but just wondering if the charging system will handle it or not ? Has anyone added one to their machine and have you had any issues?

So I picked up a 1995 Yamaha warrior a while ago and it ran decent with quite a bit of power, I was able to wheelie like nobody’s business, but I noticed that the air filter box lid had bunch of holes drilled in the top and hole in the side, also the air filter itself was serving no function and there was a huge rip in it. So I got a new air box and new filter and when I installed it, the quad lost all power and acted like it was cutting out for split seconds at full throttle. For reference I think it was running rich before because it would backfire a lot so I think it’s just restricting air flow, but how would I adjust to that because I tried leaning out the carb as much as I could but it didn’t seem to do anything unless I put the other airbox lid on with the drilled holes.
any help would be much appreciated
Also even when I put the old lid on, it seemed like just the new air filter gave it enough restriction that it still wouldnt run right

I have a Sportsman 450 HO and almost killed my self when loading it on my truck with ramps. It rolled off the top of the ramps and tailgate and nearly landed on me. I now want to winch the ATV in to the truck. My question is are the front side bed tiedowns in my 2011 RAM strong enough to winch to without distorting the hooks or sides of the bed?
