What's wrong with my motorcycle?

In the start of fall I accidentally jump-started my Honda cm185t Twinstar 1978 with reversed polarity. I saw a wire on the rectifier smoking and replaced it with a new wire. No fuses I can see are blown Once I put the rectifier back on the bike, it started up and turned over. Both cylinders fire only when I press the starter button and hold it in. It also doesn't Rev correctly without the starter button being held in. I need to know what do in order to have my motorcycle working correctly, Any advice you could offer is greatly appreciated. Feel free to ask any follow up questions you need.

It sounds like you've burned out the seal-in coil. When you press the start button, it closes a contact that allows you to start. It should initiate a coil that closes to keep the circuit closed. A apparently, the seal in function isn't working. Perhaps you can find a wiring diagram on the bike to show you where its located and how to replace it.

Get a good manual. I had a frustrating electrical problem with my CL350. It was why the bike was so cheap. 2 hours with a multi-meter following the diagnostic procedures, and I had it nailed down. I felt like I won the lotto. It just took a little patience.

Sounds like by jumping it you burned out the starter.

  • You say do I need to keep the Bell helmet the renter wore when he slipped, and crashed my motorcycle? My motorcycle is the 2008? Honda CBR600RR super sport motorcycle. The Cofounder of Riders- Share.Com compensated me the full amount of the motorcycle repairer's written damage estimate. I was also fully compensated for the helmet, which the renter wore when he crashed my motorcycle and my helmet.
  • I've just turned 18 today and i'm gonna be getting a motorcycle what motorcycle would suit me? I'm only 90-95 pounds and I'm short what would be a good light weight cruiser around 250-300 pounds like my Honda Twinstar 185? I can't balance anything too big as i'm small, I need something that's lightweight, preferably Harley, but any work for me a bikes a bike, Thank you in advance! Note: My Honda Twinstar does not run my father had that bike since I was 7 or 8 and gave it to me when I was 9 but it sat out so long it doesn't work.

  • Accidentally Took out the wrong engine cap in my Motorcycle while trying to drain the Engine Oil? My Motorcycle is a Honda XRM. I was trying to change engine oil but opened a different screw/cap just beside the engine oil drain.A 5 inch long spring and a rod with holes came out, i put it back the way i think it should be, then opened the Drain cap, drained the engine oil and filled it with new oil. But when i start the motorcycle it sounded like there's something loose moving inside the engine. What is the rod and spring that came out? Is it critical?
