G14 Counter balance shaft
After rebuilding my motor about a month ago I had to pull it again and found the counter balance shaft had broken the end off at the gear.
Out of business just before hunting season starts. Has anyone got one out of a bad motor they might want to part with ? This is a 1996 g14 300cc. Not sure what other models will fit. I am sure some of the experts on here would know . All it says on the shaft is J38 C. If anyone might have one let me know how much. I would very much appreciate it . I can paypal. Thanks in advance. |

The part that broke off at gear looked to me like it had a crack in it cause of a shiny section showing on the end at the edge. I will check the side cover and see if there was any play but it looked good to me . |

I went back to several older posts about some on here running it without a balancer. None said they could tell any difference. I don't run mine at high rpms in the woods so instead of paying close to 200 with shipping I am going to put it back together and see. |

Re: G14 Counter balance shaft
Let use know what happens. I would guess you will notice more at idle rpm, but with the engine mounts you may not notice much at all hard to say. Lot of racers don't run them in karts. Yeah is that defective or what, not at all common that I know of.
I read a lot about that and found little. One thing said the balancer does not counter the vibration, it just moves it 90degrees. This can make the mounts work better or otherwise be less noticeable to the operator it said. |

Re: G14 Counter balance shaft
Got motor back together , installed , and running without the balancer installed. Like Sho305 said it did shake a little at idle but smoothed out right above idle. Who sits with cart idling for very long anyway. Good motor mounts made it not vibrate in seat. I rode it up and down the road and couldn't tell any difference . Time will tell how it holds up . I use it around in the woods and trails so no where near any high rpms.If I ever find a balancer at a really good used price I might consider pulling motor and reinstalling it .

Re: G14 Counter balance shaft
I don't know of it being an issue for the engine, it will actually make more power without the friction of running it. They say it does not balance the engine it is for vibration for the user. The g2/9 engine some wear out the cup/bearing in the side case and they knock, they take them out.
