Why on earth would you want to do that?
The main jet in a G4 for the Twin is slightly larger than a 160cc.So you won't get the correct fuel mix for it.I still just can't work out why you would want to.


Here for a good time,not a long time.

i just find them more reliable. thanks for teaching me something.
does that mean the powertorques main jet is slightly larger than a fullcrank with a g3 that uses more fuel?

Hi Sean

Remember that the G3 is governed by positive air pressure.
The G4/LM is governed by negative pressure - a vacuum.
Fitting a G3 would mean the Twin would no longer be governed.
There's nothing worse than screaming twins mad
Maybe triplets ...

I think that's right.

goodo jack and yup , it needs the engine fan to work the G3 gove' flag . blow it out then relaxxxxxxx revs up revs down . might be possible though , never really thought about it before .
drill out the main jet for more fuel .... but thats a whole nother story !!!

if the inlet manifold wasnt so RARE you could put an oftake in it but you only have one chance to get it done right .

i know a lot dont and never will like G4 and LM's but a hard thing too do is change from one to the other
