Hey all. I recently bought the 89cc engine kit from RCMoto to replace the blown 49cc engine in my Passport clone ( this one). This is my first bike and my knowledge of them is quite basic, having only had to change the front and rear tires and one or two body parts. As such I've had a motorcycle friend help me. We got the old engine off and mounted on the new 89cc, but now we've hit a roadblock. The wire connectors are different. Is there a workaround for this? Can I simply take the wiring from the old engine and adapt it to the 89cc one? My friend said the problem might be more extreme especially if my Cub uses and alternator and the new engine uses a generator (or vis versa  ). Any ideas?  I'll try to take some pictures tonight and post them up later. Thanks Pierre Films |

Most of the Honda clone engines are very similar. I would try to remove the old electrical harness, and see if it would fit on the new engine. You might need a flywheel puller to get to all of the parts. Try to use the flywheel for the old engine if at all possible, just in case there are slight differences. If you use all of the old parts it shouldn't matter if one has a alternator and one has a generator, although I think they all use alternators. Work on the old engine first just in case you bugger something-up. Good Luck, and let us know how it works out for you. Dave

I had the same problem and it was a very easy thing to resolve
most everything hooked right up but there was one harness that didn't match up.
I saw that both had the same type of wires and that it would work except that one had too much extra plastic. I simply shaved it off with a utility knife and viola!

Is the new engine 12 or 6 volts? When I bought my Passport, RCmoto told me that their 89cc engine kits were 6v electric start, whereas the 49cc Passport engines are 12v without electric start, so some kind of adapter is required. Of course, that was last year.
hooperimports.com has lots of handy electrical parts and adaptors for Honda clone engines.
Did the new engine bolt right up other than the electrical? Just out of curiosity, how many miles did you get out of the original engine before it quit?

I only got about 6,000km out of the original. My bike is not a Jialing but a Yinxiang. They are, as far as I have seen, exactly the same. The 89cc bolted right up. My friend was able to take the old wiring from the 49cc and swap it with the new 89cc. Everything is now connected except for the neutral switch wires which are completely different and cannot be swapped. Connected the battery, filled it with fuel, added oil, but it wont start.  I'm pretty much stumped and my friend is out of town until at least next week so I'll have to wait until then. How can you tell if your engine/bike is 6v or 12v? I do know that the battery that goes into my bike (at least when I used the 49cc engine) is a model YB4L-B, if that helps. Pierre Films |

So I'm assuming you've got no spark? I'd try unhooking everything except the wire to the CDI and see if you get spark, maybe the ignition switch is hooked up wrong or something is grounding that shouldn't. Also, some bikes will only start in neutral, so it's possible that it won't start without the neutral switch hooked up. That doesn't seem all that likely though, the Chinese aren't big on safety features in my experience.
It probably says on the stator plate whether it's 6 or 12v. Disappointing that you only got 6,000 km out of your motor, the engine on mine is the one thing that seems very well put together, but who knows. At least replacements are relatively cheap.
