Re: Handling issue
I have been tinkering with toe settings on my cart since I started this post and I am curious if anyone has seen this issue.
I tried setting the tires dead ahead and took it out, uncontrollable. I set the toe in to around 1/8 and took it out, even worse. I went all the way out the front of the tires being almost and inch closer than the back of the tires, but it was uncontrollable to the point of dangerous starting around 10mph. I went back to 0 and then tried toe out. As I move the tires out more and more, the cart improves its stability at the expense of speed, and I'm assuming tires down the road. I have it set to around 1.5 inches closer in the back of the front tires than the front of the front tires and finally it feels safe to take up to 18-19 as long as I don't drive over the crown of the road or hit a big bump (those will still kick it out into a fishtail). There appears to be no slack in the steering, but the out of control nature seems to creep back in and get worse over time until I start the process again (takes about two full charges to be a problem again). Is there anything I can do or check that anyone is aware of? |

Re: Handling issue
Gonna bump this since I’m still having this problem. The crown of the road is still throwing it around almost into a slide at any speed above 10.
Currently running 22 inch tires on wheels with no spacers. Would adding wheel spacers help this issue at all? I’ve had it serviced and checked at multiple Yamaha dealers and every time it comes back it is more out of control each time and I have to start over with setup. |

Re: Handling issue
Yes, it happens generally any speed above 10 it will try to fishtail at just about any bump or change in the road.
If I set the toe-in to between 0-1/8 it is "ok" temporarily but it jumps out of that quite quickly. I hadn't driven a lifted cart before this one, so this may be common, but going around fairly gentle curves in the road requires letting it drop below 10 first. This is true no matter what the toe settings are. If I set it to toed out, it will handle fine over the bumps in the road, but will drift around a lot. I can't get pictures right now as I am out of town, but I will try to get some when I am back. |

While spacers will help with the feeling of "rolling" in turns, they won't help with the sudden fish tailing you are describing. They will help you in gentle curves. |

Re: Handling issue
I'm considering trading it off and letting the dealer handle fixing the issue, but this has me leery of Yamaha now.

Re: Handling issue
Have this same issue on my 2016 I just got, once I put a 400 controller on and go above stock speed. I think I might have fixed it today tho, I toed my front out 1/8” and was going 22 mph and didn’t notice the problem anymore. Still need to check with a couple passengers on it, as I’ve noticed it gets worse with more weight, prior to changing the toe.

Re: Handling issue
ive got a 2016 Yamaha with 6" a-arm lift. 23" All terrain tires. Mine is otherwise pretty stock. my top speed is 15mph. When im driving full speed it can be slightly squirrely at time if i hit a bump or something but other than that its not uncontrollable.
One thing i did that sounds trivial but really helped with handling was replacing the steering wheel. I bought one of the Rhox automotive type steering wheel and i swear it makes the cart so much easier to control. i do believe that you've got more issues than just the tire toe and camber. I would say it doesn't have anything to do with the cart being a yamaha but more to do with the aftermarket parts that are on it. Can you post some photos of the cart? |

Re: Handling issue
I haven't been around Yamahas much to know what the rear suspension is like but I believe it is a swingarm type with coilover shocks. A friend with a gas Marathon has the same issue as the OP. The Marathon has the same type of rear suspension. We discovered the swingarm bushings were shot allowing the rear axle to sway side to side. That makes the cart essentially a "rear steer" cart with no control. This could be the OP's problem. Handling/steering issues aren't always at the front.
