Just bought 1988 Suzuki LT250 4x4 Quadrunner

Recommended Posts

Just got the above mentioned quadrunner. First one ever. Always been a small engine tinkerer but figured I'd need a little help on this one.

Runs great for its age. Been covered up in a barn for ever. Seat is in good shape and even all the rubber cv boots look good. Just cleaned the carb, fresh fluids and battery. Only issue I have to figure out is it doesn't like to idle when its warmed up. Could be a back pressure issue due to the muffler being modified by the previous owner. Looking forward to diving in.

@DKW Congrats on the quad, those will run forever if you maintain them.  When you cleaned the carb, did you adjust any idle screws?

Just realized the speedo is not working. Looks like a cable but cant find where it hooks up. Also front break reservoir is empty. No front breaks. Gotta find the leak.

OEM is gonna be costly given the age of the quad. Try Ebay or amazon.I have an 1984 lt185 that still runs and bought new.

I have already discovered that fact and also found stuff in Ebay that I did not expect to find for a good price. Thanks for the info!

Tore into the front breaks the other day....not good. Went through the master cylinder and got all the crud out " took for ever to even get the plunger out". Got it to take some fluid then stopped up. Pulled break lines and cleaned a blew them out. Finally got fluid to the hubs. Break cylinders bad. Crap. Corroded to the point of no return..found some cheap on Ebay. Unrelated but I still dont know what that little plunger on the side of the carb is for.

New break cylinders and front breaks are alive! on to the next! "Welded" all the plastics back together and got rid of the "stitching". sanded and painted the racks. looks great! Finally road it to my shop about 10 blocks away to drag some stuff around, got her good and warmed up, and noticed when I hit the throttle it would die, Kinda had to feather into it to keep it running. need to clean that petcock first. hope its not electrical.

Sounds like some nice work on the bike so far.  Any pics? It’s  probably not electrical and more so a carburetor issue which could be dirt, sediment from a dirty tank and yes even in the petcock.  A lot of the time you will find that people clean the carburetor without cleaning the gas tank, petcock etc.  Then they put the carb back on just to find that it’s dirty again from the junk that was left behind in the tank. Also an in line gas filter also helps.

Manuel says pilot screw should be 1 3/4 turns out. checked mine and it was at 3/4 turn out. adjusted to 1 3/4 turns out and ran very rich. Smoking and would not idle. Going back to 3/4. Next time the weather clears up ill start going through the fuel system and get a few pictures. Also got a new spedo cable ill install while ive got it apart.

I've been an MX motorcycle fan forever but found out I "splat" when I hit the ground rather than bounce, so I've just invested in my first Quad ( Suzuki LT160).

Anyway...after years of buying project bikes there is one mantra you need to repeat over and over..."What did the last owner do?"

I had a PW 50 that absolutely would not run until I found out the previous owner had run a drill bit through the main jet to enlarge it. Put in new jet and it ran like a dream.

So...if the manual says it should be 1 and 3/4 turns out and that makes it worse, you might want to check and see if the parts of your carb are stock and if the adjustments (i.e., cir-clip on jet needle) are standard. Also, from your remark, "Unrelated but I still dont know what that little plunger on the side of the carb is for," the only plunger I'm aware of on a carb is the choke. Are you running it with the choke engaged?

So I've gone through the fuel system completely. Cleaned the carb. Set the valves which were a little loose. And still runs best at 3/4 turn out on the carb. Seams to have fixed the dying issue wham warm. WFO made a very good point! Next step is a carb kit. Best to know exactly what I'm working with! Thanks for the eye opener WFO! Oh, and the plunger, according to the manual is simply a kind of lock that keeps the enricher down when in, and releases it when out. Odd, but ok. No I am not running with choke/enricher enabled.

Got the new carb kit installed today and man what a difference. Again, thanks WFO for the hint. Turns out the previous owner had a smaller main jet installed. Set the adjustment screw to factory specs. She idles now and has more power. Glad we figured that one out. Thanks Quadcrazy for allowing me to be part of this. You all have helped me tremendously.

You have to find the time. Just for a piece of mind.   I’m sure your a busy person but sanity is found in the garage or shed!

      Does anyone know how to access the check engine codes on a 2018 450 sportsman. Just changed battery and spark plug . It runs fine but the light is on and I need this to plow snow and need it reliable. Any ideas . Thanks

      I am trying to put a 1994 Suzuki 250 quadrunner back into service. I have it up and running like new but need to replace the plastics as they are brittle and crumbling due to age and sun exposure. I would like to purchase new parts either OEM or aftermarket but have had little luck in finding them. I would even consider used or salvaged parts in serviceable condition. Any help in locating these parts would be greatly appreciated. Thanks in advance.

      I'm on to the next project. I am trying to put a 1994 Suzuki 250 2X4 quad runner back into service. I am currently going thru the fuel system and am waiting on some parts. In the meantime I have been trying to locate replacement fenders and I'm not having much luck.  The orriginal fenders have become brittle and cracked due to sun and exposure to the elements. Any help on finding replacement fenders, OEM or aftermarket, will be appreciated.

      Its in pretty rough shape and its gonna be my first atv, I worked on bikes before but nothing to do with quads. Anyways the quad has some problems and im tryna figure out what to focus on first. So the U joints i think are shot. The bike starts first try every time ussually have to give it a lil gas with the throttle and revs right up, idles fine but its running REALLY rich 3 starts and my brand new plug was pitch black

      Bike is L model

      Its using the original mikuni carb but im not the best at fixing the carbs and wondering if there is anywhere online that would be able to either walk me through it or help me with it i didnt see a air mixture screw so it seems like im gonna half to open it up and adjust like the float and a couple other things

      I have an older 1980s Suzuki quadrunner red lt 4wd (250)
      so just finished putting it all back together and was running fine just needed to adjust the rebuilt carb
      bf decides to hook up an air chuck to the gas tank because it got a shot of air in the gas line well 120psi didn’t agree with any of the parts including the new carb 
      end result : new battery new carb now it just clicks (one single click) won’t turn over 
      hard to pull start gets hung up (unless I remove the spark plug ) gas flooded out the first time but now does nothing purchases a new starter waiting the arrival 
      could there be damage to the crank shaft or pistons etc? Or install the new starter and try to fire it up ? What caused the starter to die after he flooded everything with gas was working fine. 
      Thank you
