floor board warping

[bucky242]

the floor board on my go kart shakes when I drive it and when I step on it, it shifts down. Other than welding a piece on it to strengthen it what could I do?

Get a thicker piece of "floorboard"?

Weld in a support bar or go with thicker as previously mentioned, most carts are too back heavy anyways.

 

[euge]

i would do that what they said, also check your welds

 

[pickledchang]

you could put in a support bar as previously mentioned, and since welding isnt an option, drill holes in the floorboard and use u-bolts or something to hold the bar in place.

and/or rivet the floor down.

u-bolt ya now I just have to find a short enough u-bolt

 

[pickledchang]

just use a thicker support bar if you they are too long, or after you install the u-bolts (i would put the nuts on the underside of the floorboard) you could cut the extra length of bolt off with a hacksaw so they dont catch uneven ground or anything. just make sure you use a good thread locker or self locking nylon nuts.

that doesn't matter I need to find a u-bolt that the threading will tighten it enough most u bolts look like this

ah, okay. well, if you cant find a u-bolt that works, you could use two regular bolts with a bracket or strap or what have you in between.

does anyone have problems with gravel on the floor because now I'm thinking about putting in a hole just in front of the seat to dump the gravel.

 

[Kenny_McCormic]

My seat is 3/4" higher than the floor so there is a drain gap. the seat in on top of the frame and the floor is on the bottom.

you could use exhaust clamps that use a u bolt and plate
