Yamaha G8E 6" plate lift

LarryLive

Guys I have a problem with front tires laying down when I back up. Going forward there is no problem. It is bad enough that I don't think shimming the shocks would help. Any ideas on what I can check for?

My wifes' cousin has a G1 that was bought lifted by swapping shocks from ? and dropping the control-arms down.We figured out that the shocks were too weak and when you go in reverse the tires turn inwards and the out-side lays upwards.We put stiffer shocks on and cured it.Hope this helps.

Yamaha's need the toe to be as close to 0 as possible. If you can do that it should cure most of it.
I also had a G1 with the same issue and never really got it so it would not bow when you backed up. We installed coil overs and preloadd them to make it less pronounced, but it never really goes away. Even my stock G16 did it a little......

Larry, I installed these "split shaft couplers" on mine and they worked very well. The springs get stiff very quick with just compressing them a small amount. Four bucks apiece!

Thanks for that info Mike, Where can you buy the split couplers?

LarryLive

Mike I noticed in the pics that you are running a Jakes lift kit. What size tires and wheels are you using with that?

Larry,
They're called shaft collars. try the link below, or if you have a J&L or MSC, etc. close by.......

The toe is the issue, you need to keep adjusting it and driving forward/reverse on pavement until it does not do it or close as you can get. If you loosen the rods I could turn mine by hand. Do this with you on the cart (normal running load), it is not that hard to do. Also if you have loose swingarm bushings or kingpins, it will make this worse. If you don't minimize the toe so its close to zero, it will scuff off your tires if you run pavement. Good time to count your steering wheel revolutions and find the center too and set that.

Note if your arms are flat horizontal it will not do this until they are not flat, many lifts angle them down a little and cause this...but then you know your toe is off while otherwise you don't unless you measure it closely. Also toe in can make them more responsive even jittery on the pavement at high speed, toe out will make it steer more vague at speed which I tend to like just a little of. Another way to sense it is go down the road and slide over to the other side of the seat while not moving the wheel, it will steer in the direction of the tire with more weight on it. If toe out it will turn in direction you slide to. When you do all that make sure tires on each side have the same pressure in them left/right, front rear difference should not matter much.

If your arms are angled a lot it pushes the front of the cart up or down depending. I lifted my cart and angled the arms a lot so this is really an issue on my cart though I rarely run pavement. It will corner nearly flat because of it, but is a pain to setup right.
