Default G9 questions

First, thanks to all for the great info on this site! Its been very helpful. I read a thread for replacing the rear coil springs with Mcmaster Carr 96485k191 springs. Since the O.D. on the new coils is more than stock, how well did they fit on the shock? How smooth is the ride, and will they carry a heavier load than stock(for rear seats and towing a small boat). Second, the sliding sheave has a groove worn where the ramp shoes slide on it. Is that normal or should I replace the sheave. Thanks in advance for any helpful input!

I am not sure about those springs but a lot of us put four wheeler shocks on our carts.

Traceman posted that he used the McMaster springs and likes them. Just wondering if anyone else tried them and how they ride with and without passengers on back.

I haven't tried them either, but wouldn't hesitate to use them going off Trace's recommendation. Since I've lifted the cart I can't go with the stock shocks anymore, and like JMZ say's, I'm experimenting with different ATV shocks. I mounted Honda 750 shocks the other day up front and it acualy rode pretty decent. Just a tad bouncy though, so want to try some other ones out.

The ramp shoes are plastic they should not wear into the ramps unless they went bad and owner kept running it. Or who knows. If they still slide well and its smooth and still a straight ramp, and the sheave moves its full range, it will probably still work ok. If they don't work right it will not shift like it should.

More spring is not going to make it ride easier unless you add more travel. Having a seat on the back (or box in my case) is a compromise. The carts only weigh 600lbs so when you try to put possible 600lbs on them for cargo it is difficult to tune the suspension for both. I have my stock springs mounted more straight up to make them stiffer to haul box weight, it does not ride as nice but with the 22s is not bad really compared to a stock cart.

Should have hot 12v on red/white going to coil/start solenoid/ignitor, while you have the key on and the pedal pressed. Make sure all those have a good ground, they are common to have connection issues, especially the small wires hooking to the solenoid. Get a ngk bprs2es (?) plug, its the normal plug for newer yami like a G16. If you are sure all the wiring is good; the trigger is on the flywheel they never seem to go bad, it signals the ignitor to fire the coil. Ignitors are expensive they don't go out that often but does happen. Sometimes when hot, sometimes they have bad wire plugs in them, sometime you can squeeze the ignitor case and they start working. The ignitor (near the fuel pump) is sort of a cdi box actually a tfi or whatever it is, it is supposed to retard the timing to zero <1K rpm for starting/idle and let it be advanced to 28 degrees at 2500 rpm and above. IIRC the timing is advanced on the pickup and it just holds it back at low rpm. Get a $5 spark tester if you don't have one.

I put the Jakes HD spring/shocks on my G9. Made a huge difference on how much it sagged down as I have a rear seat. at about $100 each it was pricy. They didn't make a spring replacement like they do for the G29.

I still have the old spring/shocks assembly if anyone wants them to test on.
