1984 Honda Three Wheeler Backfire/Engine Dies

Recommended Posts

Dont know if this is the right place for these questions. I have a 1984 Honda three wheeler with some problems. Was riding and heard a backfire. Engine quit. I looked at the pulse generator, and found the advance mechanism blew apart. I replaced it but could not get it to fire. Checked compression and had 55psi. Could my piston have a hole in it? If you can answer my questions ,please e-mail me. Thanks Bruce [email protected]

55psi is a problem, you need to take the motor apart and see what is going on in there. Could be the piston/rings leaking, could also be scratches or gouges in the cylinder, or you could have problems with the valves sealing.

I tried to pull the valve cover off, but the frame is in the way. Put it back on, now I dont have any comppression. Do I have to remove the motor to work on this thing. Found out the lever on the cover is a comp. release. I must have it on wrong if I have 0 compression. Bruce

I think you are right, the compression release may be your problem. I would check that before you tear the motor apart. If you do need to work on the motor, it would probably be easiest to work on it out of the machine.

      So I picked up a Cannibal that has been sitting for many years. I wonder if anyone can tell me where that vacuum port is on the engine. I’ve found the one to the air box, pressure regulator, and ecu but can’t seem to locate the one on the engine. Thanks in advance for any help.

      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 have permission to ride 60+ acres that vary in technical aspects. Let's make something happen. We have off street parking and it's a ton of fun.

      I bought a 2011 Crown Vic with 300k miles 12 mos ago and I'm wondering how to approach servicing the timing belt. I know very little of it's past maintenance records other than what I've done with it this past year. Basically I'm wondering if I should go ahead and attempt to replace it now, or wait til something starts to go wrong. I don't know how timing belts typically go bad...if they just break or start to stretch or what. If this is an interference engine I'm imagining a fairly bad event so I'd like to get educated and be pro active about it.

      Second...Scotty Kilmer teaches that the worst wear an engine sees after changing the oil is before the oil gets pumped back into the filter and then into the engine components during the first engine restart. But he says if you disable the ignition spark somehow when cranking for the first time again, the lack of combustion in the cylinders helps with reducing this kind of wear quite a bit. I don't have an owner's manual and I'm not sure what fuse to pull to disable combustion ignition, or if removing a fuse would be the best way to do this. Any opinions on how this should be done?

      Im working on a old 1987 honda 125 4 wheeler in the school shop. It will start by getting pulled by another 4 wheeler but wont start with the pull start or Electric Start. When you pull start it it tries to start but when you try the electric start it just turns over but doesnt even act like it wants to start. The spark plug is dry and it shoots fuel out of the back(air filter side) of the carb. Weve had the carb off twice and it is complety clean. What are some things we can try?

      I bought a Honda 250sx 1986 but the exhaust is broken. Apparently it's not possible to order a new one. I checked to order one on others compagny but there's noting.
      Do you know which exhaust it's possible to install. Is there a company who sold an exaust to fit on my 250sx.
      Sorry for my english
      Thank you

      Hope someone can help with this one.
      We took our 1984 Honda TRX 200 to the shop and they had it for about 2 weeks before they finally called and said that they had cleaned the carb and changed the battery and that it had started up.
      We went and got it and when we got home it would not start so we called them, they said bring it back in, so we did. They called us the next day and said they changed the spark plug, and that it was running. We went and got it again and it ran when we drove it off the truck.
      We parked it for about an hour because we were going to get ready to go on a ride. Well, it wouldnt start again.
      So we called them and they said the last thing they could do was order a new CDI box and put that on. I decided to just buy it myself, so I didnt have to pay them labor again. We put the new one on today and its still not starting.
      Does anyone have any ideas on what we could check to see what in the world is going on with this thing?
      Please and Thank you
