So it stays on even when in gear? Does happen in all gears where it stays on? If so, sounds like a bad switch. Try unplugging it. To eliminate the possibility of a bad switch, I would probably just replace it as its cheap enough. You can get these on Amazon like:

Merry Christmas everyone!

I think the ATV specific oils can out later in the 90s. Just make sure its 10w40. I would probably use a 10w40 oil like Valvoline 4-Stroke 10W40 ATV Oil or similar. Walmart carries it

Is this a 1987 or 1997? I know they made the LT80 quadsport in 1997 but not sure about 1987. Topic moved to Suzuki ATV forum.

Look for a vacuum leak or misadjusted throttle cable.

I typically look at partzilla, bikebandit and amazon. Depends on what you are looking for.

Should be fine as long as the trickle charger has a fully charged stop feature, so you don't overcharge the battery. The chargers in the first post are all designed to be plugged in and to "maintain" your battery.

I don't know for sure but I typically look at the aftermarket sites that sell OEM and do the lookups and see if the part numbers are the same. If not, then no. I try to go with the exact part numbers. Is it possible they are the same parts? probably.

I would pull the tank and make sure its clean. I would then replace the fuel petcock and carburetor. Then go from there. You can get a carb for $30-60 on Amazon: https://www.amazon.com/s?k=suzuki+quadrunner+250+carburetor&i=automotive&ref=nb_sb_noss_1 You can get a fuel petcock for $30-40 on Amazon: https://www.amazon.com/s?k=suzuki+quadrunner+250+fuel+petcock&crid=RUICDM3OK9K&sprefix=suzuki+quadrunner+250+fuel%2Cautomotive%2C167&ref=nb_sb_ss_fb_1_26_ts-doa-p The main thing is to make sure he didn't drop any screws into the carb, down the intake and into the engine. I would also replace that starter. which you can get on Amazon for $35-50: https://www.amazon.com/s?k=suzuki+quadrunner+250+starter&ref=nb_sb_noss_2 The entire repair could cost you $100-150 in parts.

That's awesome, way to go on fixing and thanks for sharing.

Not a dumb question at all, you would think to screw it in, so you get all the oil level and don't overfill, but the right way is to unscrew, clean and dip to check. On Yamaha according to the manual, you do not screw the dipstick in to check the oil. See below:

Very nice! Is that a 700?

Isn't that by design so that you don't over rev in low or reverse?

I would check your choke operation and idle screw. Sounds like idle is too high at operating temp.

Here is the manual for the quadrunner.

They can absolutely run hot but that seems too hot. You may have a bad ground somewhere or a bad battery, even though you got 12.6 V out of it.

Don't you have to take the big nut off like on a bike? Did you get it off?

Maybe clutch is out of adjustment? Is yours like this?

Happy Halloween! A great reason to share a older photo! Post your pics if you have them!

Me too. Big tech companies want everything. The problem is that they will never be as good as a site in a niche. The younger generation wants nothing to do with Facebook so the landscape is changing slowly.
