1994 Suzuki LTF250 - Carb Trouble

Recommended Posts

I bought a well used 94 LTF 250. When I started to repair and service it, 1 of the legs in the carb that hold the float had been JB welded. I could not find a body for a Mikuni BST 31 SS anywhere. I buddy had a mikuni round slide, I believe a VM series. It fit so I installed it with a small electric fuel pump. Did Suzuki switch to fuel pumps in 90 because of a lower tank design? It started instantly with no choke. To rich? Runs to rich everywhere but wide open. I lowered needle but still rich. Any ideas? Can the needle jet be changed? How can I identify what Mikuni I have? Should I give up and keep trying to find a BST carb?

Any help would be appreciated.

Thanks guys

You can also try contacting Sudco International. These guys are great with setting up carbs and specialize in Keihin and Mikuni carbs. They hooked my buddy up when he did the mods on his FCR 39 for his LTZ 400. Heres the link for the carb page. I never attached a link before so let me know if it doesnt work or you can just type Sudco International Good luck, I hate carb issues. They will drive you crazy. :confused:

I have fixed several of thease machines. The electric pump might be to much fuel. I use the briggs&stratton vaccum pumps, they just pump when the engine is cranking.

      It appears that the Service Manual thread at top of forum is dead as all the links no longer work.  I'm actually looking for service manual for a 2000 KVF300 Prairie that I just picked up.  Does anybody have link to one that they can share, or know where I can find one?  Thanks in advance for any help.

      I HAVE a 2002 big bear 400 4x4. I have two wires atacking to the front of the carb. What are they for?

      Thought i would share a fix that I came across. I was working on a 99 scambler 500, The customer complaint was that even with the fuel shut off the tank would slowly drain out onto the ground. First I found the fuel shut off was bad/ leaking/ dripping so I installed a new one thinking that would fix it. Then I ran it and and seen that the overflow was flowing fuel out from the bowl. So I cleaned the needle and seat and changed the float height to lower the fuel level in the bowl. Well... It still overflowed and flooded. So I bench tested the needle and seat with a pop off tester. I found that these newer style needle and seats just utilize an o-ring to install the brass seat into the carb.
      The o-ring for the seat had hardened up allowing fuel into the float bowl from under the seat. New o-ring and problems solved.

      I just recently bought a 1994 Yamaha Timberwolf 4x4 from a buddy who had the wheeler sitting in his garage for 7 years. I got it home and fired it up pushed it out of the garage and tried to shift it and it wouldn't shift. First it would click like it was shifting, but the wheeler wouldn't move and when I hit the gas it revved up like I was in nuetral. After trying some more it became stuck in 1st gear and wouldnt shift at all. But it later broke loose agian and acts like it is in neutral again. I took the motor off the machine to make it easier to work on.After asking friends they were convinced it was a clutch problem but after opening up the casing for the clutch I don't see anything out of the ordinary and am concerned that it may be a transmission problem. Any help would be greatly appreciated thank you.

      I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?

      Hi Everyone
      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

      Hello, well back to where I was last year with this carb. Took my 250 to the mountains for the first time this year and blue smoke, too much gas again. I can't believe that this carb gives me this much trouble. Seems like the choke is stuck but the cable moves freely. Anyone else ever experience this issue? Do you think a new choke cable would maybe resolve this?http://www.quadcrazy.com/atvforum/images/smilies/arghh.gif
      OK it was the choke. Put on all new cable and plunger and she is running 100% again. So now the question is, is the carb getting worn out where the plunger needle goes in the small hole and when I use the choke the needle end doesn't get lined back up with the hole?? We'll see how it runs and now that I know what the issue is I can always pull the choke plunger out and reinstall if I start having this issue again.
