So I’ve had this quad for the better part of a month, and it’s been hard to start since the day I bought it. Once it warms up it idles just fine and has plenty of power and starts no problem, but cold it takes 20 seconds minimum of straight cranking to start it.
It’s not really too big of an issue, I’m just curious as to why it takes so long. Earlier today, it took me about 2 minutes of on/off cranking to get it to fire.
i have attached a video of a cold start to show you what I mean.

Looked at this one-owner 1998 454 today. Pics below. Do you see TONS of cash being tossed into this thing? I like the low miles but I don't like the electrical "arrangement."
1360 miles - one owner that used it for hunting - owner said it has been outside, as is, for 5-6 years (he originally told me 10 years).
-a marine battery charges EVERYTHING (I didn't think this was possible) - he did this primarily for the wench - a charged 12v battery didn't turn anything on the instrument panel - a charged marine battery would help but I didn't have one in my back pocket
-no oil detected after taking off cap and I put my finger in DEEP. no gas in tank. brake fluid reservoir not dried up but has dark/old fluid
-tires w/ good tread but cracking walls - some rims rusted but appear to be straight -air box dry but filter old/useless -original carb - didn't take out to inspect
-foot shifter felt good/cycled through the gears -pull start worked but I failed to check for spark
-and then there's the WIRES... and WIRES... and WIRES. Basically neuroanatomy 101. More like Arctic Cat Nightmare 101. New wiring harness on ebay runs around $70 - but this guarantees nothing.
But the plastics are good
Thoughts and opinions welcomed. "Run away" -- "You're an idiot if you pay more than $XX for that piece" -- "Don't even THINK about it"

I recently picked up an ‘07 KFX 700. All was going well, rode it about 40 miles, when it started bogging at low speeds. If I kept the revs higher, I was just fine. Also, a persistent issue since I picked it up is the fairly difficult start (but it is abnormally cold right now and the quad is jetted for the dunes at summertime).
Regarding the complete lack of idle, I have to rev it a couple times to get it to idle after starting it, after which it’s 50/50 whether it remains idling. I don’t have low fuel, but all of this began after I rode it pretty hard and the radiator fan kicked in. Might be overheating, just wanted to hear your opinions.
So this 98 Big Bear is my new project. While I'm waiting on a few parts to show up, I'm working on a few small things. I can shift 1-5 just fine, no problem at all (keep in mind, this is not running yet so just manual shifting sitting still). However, I can't shift from 1-neutral. I can hold down on the foot shifter, rock it a bit, and it will disengage the clutch so i can push it around in neutral as long as I keep pushing down on the shifter. However, it will not downshift to neutral and stay there. I know BB's have had some shifting difficulties in the past, but before I dive into this, have any of you fine folks encountered the same issue? I'm tempted to just adjust the linkage a bit since these have an external linkage, but thought I'd toss the question to the group and see if there are any common issues to look for.

Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.
What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.
Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
Thanks in advance.
This is my first post and I was wondering if there is anyone who can help me solve a problem I have with my Yamaha Kodiak 400 4x4 Fitted with a Mikuni Carburetor . The year of the quad is around 1998, the reason I am not sure of the date is, there wasn't any paperwork and no details on the frame either.
The quad had a bad leak from the carb overflow which indicated that the float needle valve was blocked or passing so I replaced this and put everything back together. The quad ran really well until I took it onto some rough ground to have a ride around, a few hours later the engine started to run really rough as if the engine was flooding. I have removed the carb again and cleaned the needle valve out and the whole of the carb just in case there where any dirt behind it. Engine now runs fine again but fuel has started to run out the carb overflow again.
I have tried everything to try and stop the fuel leaking out the overflow but its still happening. My last thoughts where to adjust the float level and its still happening.
Has anyone got any thoughts on the problem or could suggest whats causing the fuel leaking out the overflow.
Thanks for reading
