New project - LT80

Recommended Posts

Picked up an LT80 (unknown year) for $200 recently for my girls. Not running at the moment, but does turn over. I’m thinking the carb needs to be rebuilt or replaced, as it appears to be leaking 2 stroke oil. Anyway, I’m excited to have something to wrench on in my (limited) spare time :)

That's a cool little bike. It should be oil injected, a small tank under the seat?

The carburetor can easily be cleaned out and compression should be about 90psi .

Its a small carb so be gentle.

Thanks Frank! I did see the oil tank under the seat. Not sure where the oil is injected though (I assumed the carb). Doesn’t appear to be leaking from the tank. Sounds like I need to break it down and investigate further

Yes definitely needs to be taken apart. Its not a difficult task.   The oil line goes right into the side of the carburetor. If your not familiar with the carburetor rebuild there is topic on it here.

Update: started stripping her down today. Hoping to have it down to the frame over the next day or two. Looks like I’ll need to replace the wiring harness - it’s cut and melted in numerous places. The exhaust bolts are going to be a problem a well... pretty rusted and slightly rounded. Other than that, no surprises 👍

FINALLY got her stripped down to the frame.... really should have checked with wifey to see what outstanding tasks I had on the honey-do list before taking on this project 😊That and crappy weather set me back a bit.

Ordered a new set of handlebars and bumper guard. Once those come in, everything is getting powdercoated. I’m thinking pink with sparkly purple accents 🤣 love my girls

      Hey guys, figure you guys would have some helpful direction or answers.
      So, 05 Sportsman 700 carb, new carb, fuel pump, new plugs, new air filter, new everything I can think of that is usually the running issues. Starts up fine, seems to run fine, but if under load, two people, or even one person, up a hill, or pulling a drag chain for the driveway, it starts to cut out and sputters and loses all power, until I back off on the throttle and just barely try to let itself catch itself and then I can take off again.
      I am going crazy trying to figure this thing out. Other than that, the quad runs great. Parents bought bran new, just used around the property, 5000 miles on it. Any ideas???

      Does anyone have a redcat 250 or falcon 250cc that they can share where the two vacuum lines on the carburetor that you run antifreeze through I honestly have no idea where the lines are suppose to go to circulate the antifreeze. 
       
      Any help is greatly appreciated.

      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
