I just brought home a used 2005 Yamaha Big Bear 400 4x4. It needs front wheel bearings, and a new choke cable. I think i can handle those two items. However, when i went to look at it, it ran good, shifted good, brakes all workds great, but at home when i started it, it would idle nice, but when i gave it gas it seemed like it was flooding out and would die. If i just gave it a little throttle it built up RPMs but any more throttle it began dying out again.
any suggestions why it's doing that?
I'm looking for a service manual, but forum rules say i have to make 10 posts..lol
oops...i just realized i posted in the wrong section of the forum!!
First time working with a Honda-Matic transmission. I didn't even know what I was getting into when I purchased this running beat up farm workhorse quad with black oil. I was thinking I could tear the cases apart and find the bad bearing, causing the random squealing noise when you put it into gear and give it gas. Upon opening the engine covers, I Learned about the Honda Matic automatic transmission and realized there's more than just an electronic shift motor going on in these quads. With my learning curve in major education mode, I'm now wondering two possible culprits to the squealing as I've torn the motor down and am staring at the Honda Matic transmission.
Two possible issues:
1. The bearing that is squealing is unfortunately inside the hondamatic unit hydraulic transmission which is apparently not serviceable? A new unit is $1,900 to replace it! Yikes!
2. The pull starter rope snapped and someone replaced with the wrong pull starter rope that eventually became severely worn out and the centrifugal lever/catch shows signs of wear from rubbing against the housing.
Thinking now the pull starter has nothing to do with a squealing that loud, so my attention is now on the Hondamatic unit,
Has anyone gotten inside their cases to inspect the Honda Matic transmission?
There's a only 1or 2 videos out there that are not helpful for tear down and inspection.
I understand it can't be rebuilt but wondering if anyone has looked deep enough into one to clean it out from running dirty oil? Possible identify bad parts.
I refuse to believe Honda is engineeering these as completely non-serviceable?
Thinking I will try to disassemble the Hondamatic unit m. Hopefully get into it and get all the dirty oil out and replace with fresh? Any special tools needed?
Any and all thoughts/experiences with Hondamatic units would be great conversation for me..
Finally getting around to the Yamaha Big Bear that followed me home in August. It is a mess. I got it off of marketplace, the add stated " runs like nothing is wrong the only thing that's wrong is it needs a new wiring harness". So iv been looking for a new wiring harness although it came with a wiring harness that was out of the bike, so I assumed he had ripped it out. All the plastics were off and no screws or bolts to reinstall but they were in good shape. The coil, voltage regulator and starter solenoid was missing but came with new one. So I go out expecting to start installing the wiring harness and find out its still in tact with these parts missing. The first thing I found was the engine was stuck and there was no spark plug in it. I noticed when I bought it that the pull starter wouldn't rotate the engine but he assured me the engine wasn't stuck that there was something wrong with the pull starter, I was skeptical but took him at his word. I didn't check it that closely because I was really just buying it for the tires and wheels they were worth twice what I paid for the bike. Im a little new at buying on marketplace and am just angry that someone would lie like that, now I don't know if anything is really wrong with the wiring harness, im probably too trusting I usually trust people until they give me a reason not too. I would have bought it anyway, if I go to the trouble of hooking up my trailer and wench and driving there its coming home with me, long as its a Honda or Yamaha I can fix it. It took PB Blaster about 24 hr and I got the engine freed up, and it has good compression, using ye ole thumb over the hole test, and the pull starter works fine Thats enough of that, now for my real question, before I go to the trouble of chasing the wiring problem down I would like to see if the engine is ok , is there anyway to feed voltage directly into the cdi to make it spark.
Hey guys and girls - I’m at a loss and need your help!
My jianshe 400 ML has been starting great on pull start but nothing on electric. Narrowed this down to starter clutch so have changed this and now engages fine.
problem is since changing she struggles to turn over. Had it hooked up to a car battery just to see if it will flick over but to no avail.
Has fuel to carb
absolutely fine turning over with spark plug removed.
Any clues appreciated!!
Just a shot in the dark here..but...
Does anyone have the red rear plastics for a 2000 honda recon in eastern Georgia areas?..
We live in Millen area..it is in between Waynesboro and Statesboro
My 17 year old grandson has somehow tore ours up and the battery pocket in it is even busted and the battery is hanging now
Dont much care if it is faded or not..it will be getting rebuilt soon and we probably paint it anyhow
