Does anyone know if these kit will work on the old G23 heli motor.

I emailed oneill brothers and they don't think it will work because it is a heli motor. But I think it should work since it is just the top end being rebuilt. I know the cranks are different but I am just want to rebuild the piston and jug to a larger bore.

From what I see, the kits are for a Chung Yang motor (cy) 2 bolt flange cyl.

The motor used for Heli's is a PU. 4 bolt flange cyl.

I was looking at this at one time,

but the 13:1 compression is going to cause vibration so I had second thoughts. I decided to leave this kind of thing to the experts.

IMO, your best bet is to talk with Al at Hanson's to discuss options. He moded my G231PUH and it runs great.

According to the oneil brothers site you should run 92 octane with the higher compression ratio. I don't know how true this is but it makes sense. I don't know if the davesmotor would work on the older G23heli motor. If the bolt pattern is the same, it should work.

The large bore piston and jug can be fitted on a 23CC motor?

Would I also need a large bore carb?

Yes, the 23 carb is too small. Peace, Toxic Al
