I have a 1988 Quadrunner 250 2wd. My brother in law sold it to my son for $20...had been sitting outside for several years. Got it home and had it running in about 30 mins. Ran it a bit and then went to looking at the carb as it was having trouble idling. Was getting it pretty close, then started losing spark...Also, it wouldn't start up every time...only about 1 in 5 tries. Anyway...now, it has what I can only describe as "intermittent" spark. I can get 1 light spark right when the start button is pressed and sometimes one when it's released...but none while cranking. 🤷‍♂️ I have replaced the spark plug, ignition coil/wire, and traced wires best I can. I noticed a couple frayed wires at the pickup coil where it enters the case. So, now I have the cover off, stator and pickup coil out and trying to test the coil. I do have about 114 ohms resistance for pickup best I can tell. And I can read minute voltage when I drag a magnet across it. Could it still be bad? Can a bad ignition switch/button cause this? (I did have the switch off to oil the choke cable)...pulling rope makes no difference though...any ideas or help would be greatly appreciated!!! It's the intermittent part that's throwing me off!

Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves. From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next. 1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match. I have no idea what this would cost. 2. Buy a replacement head+cam+valve cover. #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option. However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number, 11100-19B10, instead of 11100-19B01 like for all earlier models. What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years. Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical. Would those work as well possibly? I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on. Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me. Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

I am looking for a PDF version of a manual for a Suzuki Quadrunner 250. I am not sure of the year, but believe it is a late 1990s model.

I recently purchased a Suzuki Quadrunner 250. I am not sure of the year. I plan on rebuilding the carburetor and looking to do some maintenance before using it. I also purchased a Quadrunner 160 and planned on doing the same maintenance. I have the same question for the 250: I am going to change the oil, which is simple enough, but after reading the manual there are many adjustments that are needed when the oil is drained. Does anyone have any advice on the valve clearance or clutch adjustments? Both require the oil to be drained and the engine at top-dead-center. Anything else that I should do while it is in this configuration? I am unable to find a manual online for the 250. Does anyone know the valve clearance setpoint?

My quad will not start when temperature is below 40 F. Starts and runs great in warmer temperatures. My choke doesn't seem to be working...should the plunger be "IN" (down) or "out" (up) to actually "Choke"? Not the little choke lever...the actual plunger in the carb?

ok so i have been searching for a 12 inch rim for my quad but with the lug pattern on the quad (4/140 mm) I haven't been able to find them so i decided to look at tires but with the size of the tires (25/12/10) and (22/8/10) they are a hard tire to find and when yo do find them they are either to cheap to be a decent tire or to expensive to afford does anyone have any suggestions or just tell me what you did for yours

Hello, recently I removed my starter because it was to slow so before buying a new one I thought cleaning it. So I did and it did went much better. The thing is I replaced it exactly as it was but since then the starter goes freely like there’s no dentelywheels. Did I do something wrong ?

Just got the quadrunner. Seller showed it would start and run a few seconds on ether. I ordered a new fuel pump and installed it. Put 2 amp charger on battery and tried to start-NOTHING. No lights come on , etc. Acts like battery is dead but it isn't. HELP Please!

One 1998 Quadrunner 250 4x4, two 90's King Quad 300's worth of parts. Fenders are garbage..

Hello! New member here! Retired Navy Submarine veteran living in Georgia. I just picked up a 1998 Suzuki Quadrunner LT-F250 for CHEAP. Small 4WD double locker was exactly what I needed. It had LOTS of issues...gasoline in the crankcase, NO brake shoes, blown wheel cylinder, smokes BAD, only shifts into 1st, 2nd, and reverse, etc. Looking for all the help I can get to sort things out.

Hey all, I've been working on getting up enough posts to download the service manual, but in the mean time, maybe someone is interested if giving me a few deets in a reply? If not, no worries. I'm look to confirm a couple things that I've picked up from Google searches. First, I've heard that the factory mixture setting on the carb for this bike is 2 full turns out. Can people confirm? I've also heard that it's a fuel mix valve, not air, so screw in to lean, out to richen? Is that correct? And for the valve clearances, I've heard two different specs, one is intake 0.004" and exhaust 0.006", and that other I heard from a youtuber who claimed this bike had 'very tight' valve clearances, said 0.002" intake, and 0.004" exhaust. If anyone wants to comment on the above, I would be appreciative, if not though I'll keep posting until I can download that service manual

Hello ! Does anyone know why when I start my quad the idle go very fast ? The only thing I did is change the fuel line and the fuel filter.
