Yamaha G9 cdi in a G2 cart?
So I have an older G2 Yamaha cart bypassed the governor it runs great ~20mph vs 12-13mph factory setting with 3 people on the cart but from what my understanding is the g2 cdi unit has an internal rev limiter as the cart will pull really hard then feels like spark is completely cut then a couple seconds later it will start pulling again. Has anyone successfully swapped a G9 cdi into a G2?

Yeah its not that hard... Just be careful not to burn up your motor and install a tach!
What you have to do is pull up the service manual and look at the two wiring diagrams and match them up from there. Do not quote me and you'll have to verify this but if i remember right G2: Br=Power (from relay), O=Ignition Coil, R/W=Ignition Coil, W/B= Pulsar, W/R=Pulsar, B=Ground (off SG), R=Oil Light G9: R/W=Power, W/B=Pulsar, W/R= Pulsar, O=Ignition Coil, B=Ground Match up the corresponding wires but now you'll notice that there are 2 more wires on the G2, one being the oil light so that is gone and the second being a second coil wire. I can't remember if can use your old ignition coil or if you need one off a G9..... but I am guessing you will need a new one. I did this awhile back to one of my old carts. Its really not worth it IMO unless your coil pack is already burnt up and need a new pack. Hope this helps and don't blow your motor up!!! |
