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.

      My retaining wall fell 20 feet up my driveway from the entrance. I called my insurance company and was told that there isn’t a lot they can do.
       
      So I called the town to see who built it and the old homeowner did 4 years ago! With no contractor! And the building department passed it for inspection.
       
      There is no geo grid, no drainage, and dirt as a backfill. I bet you I can pull the rest down by hand.
       
      My question is who is responsible? This is not right.

      I recently purchased an 07 Honda sportrax and when I was checking the spark plug I saw the boot was ripped nearly in half. When I removed the plug it was blackened and covered in oil. How can I thoroughly clean the plug hole and remove any debris that is in there? Is there a small tube like vacuum or something of the sort made for stuff like this? The machine my dentist has would be perfect, maybe they do rentals! 😁

      I am working on a Honda sportrax I just got my daughter for get birthday and the reverse and neutral light are not working. When I traced the wire down I saw that it wasn't plugged in but I don't see where it is supposed to connect. Does any one have a general idea of where I should look?

      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
