Hi guys and gals,
I bought this 2012 Chinese beauty, has 3800 miles on it, 300 miles since having the 80cc BBK installed.
When I bought the scoot I was told I would probably need a new battery. I was able to trickle charge it and generally able to start it with no issue before the BBK. Since the BBK, the battery simply does not seem to have enough umph to start the bike. Occasionally, once the scooter is well warmed up I can get a start from the battery, but I usually end up kicking her.
It also seems that lately, kickstarting is becoming less effective and is taking several kicks to get her going.
My questions are: Would a new battery be my best bet? Any recommendations on a good replacement/upgrade I can order online? (It seems that some places also won't ship to HI) Is there anything I can tweak or tinker with in the mean time to make kicking her easier?
Any help would be appreciated.
Stay safe all.
Jay

Thank you John!
After reading the thread, are we talking new battery and CDI? Or new starter clutch as well?
I do like what I am reading about your CDI's, but it seems like I am reading that a new battery is needed as well.
Thanks again.

Jay I had the same exact issue when I upgraded from 50cc to a BBK. The problem could simply be the starter you have does not have the torque to push the now much higher compressed engine over. I tried a new battery and did not have much better luck starting until I got a new electric starter motor. I also had to get a thicker head gasket to lower the compression a little bit. If kicking it is also hard to do I would think it would be that you have high compression that is simply too much to start easily. Check the valve clearances, though they wouldn't make much of a difference if it has too high compression, just a matter of the power required to bring it to life is more than you can provide safely with the kick starter (watch out for kickback, they can bruise or break a leg in extreme circumstances) and more than the electric starter provides. If the new battery doesn't help and you have a stock CDI, not a racing advanced angle one, then you might wanna try a new starter motor with a little more power. I got mine for $25 with free shipping on ebay from a seller who sells performance and regular parts for GY6 motors. Have had no issues turning the motor over with the electric starter since. |

You may need larger wires going to your starter, if the wires can't handle the juice, the starter starves and can't turn the motor over. This is usually only needed when putting in a larger starter motor.

The original battery cables are crap!
The core of the cables are too small, it's only the red rubber around the cables which are a bit thicker. The area of core is too small to push enough juice to the starter. Check your battery cables and if they are as bad as mine, buy some jump starter cables and use them as battery cables on your scooter.
Change both positive and negative cables...

That's a good tip and project to add to the list. What gauge wire do you think would be sufficient? |

I do like what I am reading about your CDI's, but it seems like I am reading that a new battery is needed as well. Thanks again. The guys brought up some good suggestions, battery cables and engine ground can be on the thin side. I would say if your using stock cdi your ok . if you go to a performance you may want to stay away from fixed advanced cdi. My thought is your starter clutch at this time is no problem. The starter clutch gets stressed with a fixed advanced cdi, because it sparks to early and causes kickbacks, that is what breaks the starter clutches not high compression. The high compression will make the starters work harder, with a weak battery it will show itself. John |

Thank you everyone for the suggestions.
From what I'm reading, perhaps I'll start with replacing the battery cables, and see what that does. Even if it does not end up being the fix, it sounds like its probably not a bad idea in the long run, particularly if I do end up also replacing the batt, starter, and cdi.
I may go ahead and get to work on that this afternoon. Will post back with results. Any recommendations on wire gauge?

People will have differing opinions on gauge, but a cheap easy trick is to use the wires from some old jumper cables. |

Like is there a gauge that would be too thick that it would not work well or at all? |

If you can get it on the posts, you're probably fine.
