Hmmmm,,,,You said it had an over sized Carb....85-86 lt250's came with a 32mm TM Mikuni flatslide, I believe the 87 and later had a 34TM.....With a Stock motor I wouldnt go much bigger than the 34....Check your reed carge as well...

BTW....dont ever let anyone tell you that Trikes are Dangerous....:wink:

I have an 87 and have a stock bore, stock carb. I have Boysen reeds, Fatty pipe and silencer and a K&N and I am running stock jets in my carb. I have no problems with power or fouling and don't run to lean.

Start with the simple things first....Maybe just a tune up will do the trick....Have you ever checked the spark Plug???? Fouled???? If not,,,Gaped right??? Make sure you know how to read a plug too.... How about the Air Cleaner???? Plugged???? Remember....Fuel, spark and air.....FIRST!!!!!

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      I installed a new China made carb months ago. So far all is well.  This carb has a heater, while the original did notI never considered hooking it up.  Here in far N. Ga,  0 deg. is about the coldest it normally gets in a bad winter. Should I bother hooking the heater up and will it need a sensor or just an off/on toggle switch? Totally new subject to me.

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      I have a 1999 Sportsman  500, it was running fine, than started to lose power in the winter, I adjusted the idle screw and away I went, than a few weeks ago it died, I have found that i am flooding the engine, compression was at 70PSI and due to the compression release mech. i assume i am good as it compared to the same PSI on a 2000 sportsman 500 i have. i cannot start the atv unless i go full throttle and it starts an runs for about 30 sec than dies, again it is flooded. i ordered a new carb off ebay as i could get one for around $40. put that in same issue, i have checked the timing, (good), valves out of adjustment i adjusted to .006 still same issue, i have found the exhaust lobe and rocker arm to have some wear, i have ordered new ones, but am looking for any other input in this area as well. would the exhaust cam and rocker arm cause the engine to flood? i have used a bore scope and the piston liner has good cross hatching still? any input would be great.

      A friend of mine has this Bayou 220 that started running bad and parked it a few years ago. I foolishly volunteered to take a look at it. I noticed right away the choke plunger on the carb was broken and probably the reason it was running bad but now the old gas was evaporated and like turpentine. Before i even tried to start it, i drained/ thoroughly washed the tank out, new fuel filter, new fuel lines. Blew air through the petcock etc. Changed the oil and filter and air filter and new choke plunger and cable. I disassembled the carb and rebuilt it with a kit. I cleaned the main jet with solvent and poked a wire through it to make sure it is clean.. the engine now fires right up with the choke on and dies when i take the choke off. I adjusted the air/fuel screw to about 1.5 turns out and the idle screw about 2.5 turns out. The rubber boot between the carb and head does not have any cracks in it so I don't think it is leaking air. I originally had the clip on the needle on the second from the top ring... when i moved it all the way to the bottom it starts, runs and idles really fast and will idle eeally high with the choke off but if i adjust the throttle cable and/or idle screw to a slower idle it will sometimes stall but the idle will go up and down every few seconds and when you give it gas there is a hesitation... i tried moving the clip down to rhe second from bottom and same problem... i replaced all the parts in the pic to the top right. However, there appears to be a small o ring, washer and spring left over from the kit... i did not see these get removed..... a) any idea if where these extra parts go and if i need them and b) any other ideas on why i cant get it to idle right or carb adjustment ideas?
      Thanks

      What is the best and easiest way to tune your carburetor? Any tips or tricks?
    • By LTZ-Zach
      So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
      I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
      It will run and idle decent now but when I give it gas it dies.
      Does anybody know what could be wrong?
      I also changed the spark plug and air filter along with the oil and oil filter.
