Reviving a 2000 Big Bear From Storage

Recommended Posts

I have a 2000 Big Bear 400 4x2 that has been sitting since about 2005. It has been inside, so it still looks very good. Bike was low hours and ran great before it was parked. I plan to change the engine oil and filter, differential oil, battery, fuel lines, fuel filter, drain and clean the fuel tank and rebuild the carburetor before I even try to start it. Is there anything else I should do? I don't want to cause any damage before I even get the thing running again. Thanks.

I will also replace the spark plug and the air filter and check/clean engine ground connection as well.

i have a question for all the gurus on this site.....just about that very question....i too have a 4 wheeler that has set a while...i went thru it and checked and cleaned everything on it...started right up and idled fine, before i could even try any adjustments it died...did that 3 different times and final time locked the engine up!!!  it is a kawasaki bayou 220 dated 2000...

the question i have of the gurus is...is there a way to oil these from the top end, since they have been setting, and the oil surely has all drained out of top end and would that oil sufficiently to prevent issues once engine going??????

Thanks,

May be a silly question, but you did remember to put oil back in it, didn't you? I don't know if you can access the top end easily on that particular machine. Is there a way to manually turn the engine over without the starter to see how much resistance there is? I don't like using the starter because the torque they put out can break stuck rings.

That sounds strange. Hopefully one of the experts will be along shortly with a possible solution. Did it get hot at all while it was running? Have you checked to make sure the starter isn't stuck in the engaged position and keeping the engine from turning?

If the starter stays engaged to the flywheel, it can eventually seize and shut the engine down. This will cause the symptoms you describe.

The engine won't be able to turn because the starter is locked up to the flywheel, preventing it from turning. If the flywheel can't turn, neither can the crankshaft.

I'm not familiar with your machine, but you might. Something is preventing the engine from turning and I wouldn't think no longer than you ran it, it would be the crank. Then again I'm only a jakeleg redneck and I didn't even stay at a Holiday Inn Express last night.

I'd pull it to save $80. From what Google says, it's pretty straight forward, albeit a but tight to get to. You might wait to see if someone more qualified comes along in a bit.

For plastic tanks, I remove the tank, empty it out, and plug all but the filler hole. I then rinse it with hot soapy water the best I can and check it with a flashlight. If there is still buildup present, I put a little aquarium gravel and hot soapy water in the tank and shake it to agitate the gravel, which usually loosens anything stuck to the tank. Once I'm satisfied it's clean, I remove the soapy water and gravel and rinse with hot water. Let it dry and inspect with a flashlight for cleanliness and to make certain there isn't a pebble stuck somewhere. That's about it. You can use solvents and such, but I don't like to. Metal tanks can be cleaned in a similar fashion, but if you have rust it gets exponentially more complicated. There are many videos out there on cleaning and coating metal tanks. You can get about as elaborate with that as your patience can stand.

      So my front hub broke, I’d like to put aftermarket on. Hard to find new oe ones. Please help. I’m new to all of this, I have some car knowledge and try to apply it

      Several months ago, I finally got around to fixing the bayou. Rebuilt the carb, replaced the fuel selector switch, hoses and fuel filter, and she ran great. Only had 2 minor issues since then where, at higher speeds, it acted like it was choking out when I let off the throttle.
      Lately I've noticed if I let it go for more than a week, it almost drains the battery dead trying to start. I initially thought battery, but after inspecting I found very little if not any fuel flow through the line until it starts and runs.
      I'm a little baffled and don't have much time to mess with it as most my free time right now is spent on getting my rv up and ready for hunting season in the next 3 weeks. So any help on quick diagnosis checks would be helpful. Otherwise I'll just keep starting it every 3-4 days to keep things primed until I'm done hunting.
       
      Oh, and another question on a different topic. Does anybody know what the mounting brackets on the front rack are for? I'm referring to the 2 angled metal tabs with threaded holes that are located on the left, near your knee when sitting on the quad?

      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
