I used this kit on a dingo build with a stock 301, 18" tires, 5.4:1 gear.Harris, welcome to the forum. I've owned a couple of yerf-dogs, still have one of them. Front of your kart looks like one of your tie rods is way out of adjustment. I wouldn't go through the trouble and expense of putting a rack and pinion on it. Stock stuff works well enough when adjusted true. Do as suggested by Denny. Get rid of that clutch, and get a torque converter. Your 301 has a 1" output shaft . You can run a 40 series. They come with a 1" driver clutch . Most 30 series come with a 3/4" driver, but you can find 1" set ups . The reason I mention this is because the 30 series can be had for about 1/2 the
money of the 40, and are easier to get set up. If for any reason you are thinking about hopping up the 301, then for sure go with the 40. The 40 is much more robust and the 30 world be at its limit on a stock 301. Your centrifugal clutch that's on there now won't hold up for 10 minutes.
The tie rod ends are a great idea and at that price, I'll go ahead and order those.
I doubt you’re going to find an original seat....
Looks good to me!BAM! https://www.gopowersports.com/yerf-dog-carter-go-kart-double-seat-cushion/
I'm not saying to buy it, not saying it fits, it sure isn't "original" (it's a repop) and it doesn't have the Yerf Dog gray color or paw print logo but it might fit the kart in question. MEASURE.
