recently picked up some project bikes off CL for cheap. got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start) plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows. things I see: carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.
I picked up my first ever ATV on friday. It's an 89 Big Bear. It has some cosmetic issues, but seems pretty decent mechanically. I did have trouble getting the idle tuned to the book spec of 1,300 - 1,500 RPM. I took the carb apart and cleaned it out. Somebody must have lost the spring for the pilot screw, as it's no longer in the carb. Also, I have a dual cable carb, I noticed all the IPL's show the single cable carb, but I see others on youtube had dual cable carbs. When I would adjust my idle speed screw, nothing would happen. I bottomed it out and it didn't seem to make much if any difference. When i pulled the carb apart I saw the screw doesn't even touch the linkage, it's too short. Do the two different versions have different length carb screws? I'm wondering if somebody lost the ordinal, replaced it with the IPL number for a single cable carb which is shorter, and gave up on getting the ATV to idle. If you hold the throttle just a bit to get it to the RPM range listed above, it "idles" great. Any ideas? Or any links to the dual cable IPL?
Have you guys have good luck with the aftermarket intake boots? Or is this a buy once, cry once deal? I'm guessing the OEM units last longer, but there is a huge price difference. If you have had good luck with aftermarket, where did you get it? My current boot doesn't seem to have any air leaks, but it's encased in JB weld...
I'm getting a 9th digit check sum error on the ATV when I put the VIN in. Has anybody seen this before on a Yamaha? The VIN number looks original as well as the paint around it.
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?
It's been a while since I posted. Fan trouble and the replacement I sourced on amazon is still working great on my 2005 Suzuki KQ700.
Unfortunately this year I lost my outdoor best friend. He's that go to guy for everything … the day run, may walleye opener, last minute hey my boat's at work get your a$$ over here with your rod and let's go kinda buddy. I bought the quad last year in March and with him gave it the once over and prepped it for fall hunting season, but cancer took him before we could enjoy this new aspect of outdoor life. We planned an October trip into the bush with our quads guns and tent trailer. It never happened. A tribute to our fallen and lost.... But in their memory take the opportunity to grasp every minute of the outdoors you can, life is short... you can sleep at the end...
I've curious what everyone has been doing to prep for the spring season. I mounted my battery and the quad started up straight and easy, just powered it up once or twice to juice the injectors and it fired up after a couple of seconds. I let it run, confirmed fan started, checked charge voltage. all good. I did all my oils in the fall to make sure no water was present anywhere so skipped that this spring.
So what have I done over the winter to prep for quadding? I've been researching. This year I am going to cross over quading with brook trout fishing. So I have been pouring over my old maps from my youth, google maps... looking for those faint markings of trails I can't travel in my F150 (well not yet, paint still looks pretty good ).
