Wobbles at high speeds.

[Bighomedog11]

Hey I notice when i start maxing out on my kart it will bounce like. And make the ride not smooth. It will kind of start to feel like I am on a tractor. I am wondering why is it doing this? Could i have a bad bearing or what could be making it ride rough when i start to max out?

your kart may not have hardware that can handle the speeds your reaching, how fast you going, pics of kart?

 

[Bighomedog11]

Umm well i am not going that fast. The motor is stock just removed the governor. I posted pixs of my kart in another thread you had replyed to. It is the same kart.

Tire out of balance?

 

[Bighomedog11]

Might be. Not sure how to balance it though.

 

[Benjo]

could be the fact that you have no suspension.

hey big, I have come across this before.
IF the wabble feels side 2 side in front its your bearings ... in the front you will see and notice this.
IF its up and down, then they need to be balanced .... in the front you will see and notice this too.
IF it wabbles up & down and it feels like the whole kart is doing it then the rear tires need balenced.
Put the kart up in the air ( dont start it ) and rotate the tires, axle. if you hear ever the slightest grinding from a bearing then replace it.
IF your flying down the street and you feel a sudden extream up & down wabble then you just blew a tire.

yup, chances are your tires/wheels are off-balance or at-least one of your bearings is shot, they sell tire weights if your interested, also if you get new bearings make sure there high-speed bearings. sry for no recognizing you so quickly, i look at ALOT of posts on here and i was up till 2am east coast time

Its because you are running tires designed to go 10mph.

Oh its fine, Yeah i am going to first go about changing my bearings and making sure my tires are balanced..

Never knew tires had a speed limit on them.. LOl thats not whats causing my problem... Lol tires don't have a certain speed limited!

Lol tires don't have a certain speed limited!

BS. Yes they do. My kart tires are rated @ 25mph i believe.

Ever see them marked with NHS? Non-highway service. A.K.A. Don't go fast with me installed.

 

[DirtTrackRacer_07]

I can about bet that it is a wheel bearing.

Check your bolt or spindle that the tire runs on and see if it has any worn grooves in them, they may be worn out.

Also check out your tie rods ends - if they are loose when you are goin fast, they can cause a wobble.

have you ran over anything or hit anything with a tire?
If so one of your rims may be bent.

tires and rims definatly have speed limits, the bugatti vayrons tires had to be specialy desinged to handle the cornering g's at 260mph! which is double the g's going 200mph http://www.roadandtrack.com/tests/car/2006-bugatti-veyron-16.4 "Michelin spent millions of dollars developing tires that were strong and heat-resistant enough to go 260 mph yet compliant enough for everyday driving. A set of tires alone costs $17,000; the special wheels with Michelin’s run-flat PAX system are an additional $43,000."
