i will probably be filling in all the holes and using polished aluminum diamond plate to fill all the holes and use as footrest grip, i will be building a custom seat, custom frame, direct steering. i also plan on widening some wheels to give it a better stance.

Dont forget to build your spindles with the right adjustments. One of the Mowrons can help you out.

Response from a Mowron...

We run up to 45 mph on our tractors and they ride smooth and track nice and straight.
The secret is in the spindle angles.  
We run 0 degrees Tow, 0 degrees camber, and +10 degrees caster.  Stretch custom fabbed front axles for all 5 of our tractors. Check the build thread in my sig for an example.

Of course when you're running that kind of speed, also upgrading all of your steering linkage and steering box is highly recommended.

my grandpa has that same tractor. kinda brings a tear to my eye to see one go like that, but i also like to see it go, its just too small for me to fit comfortably. anyway, its a good start. solid body. id reccomend doing direct steer, i'll look around for the thread tomorrow and post it in here, or PM. id also invest in some heavy duty spindles from BMI karts. AYP is notorious for weak spindles..

I was planning to build direct steering, and i'm also gonna tig weld some 5/8" grade 8 bolts onto 1" high carbon steel tube , i was also going to weld some 5/8" id to 1" od high carbon steel to build a strong set of spindles, then i was also planning 1" to 5/8" brass bushings or bearings, and using a 5/8" grade 8 for the spindle kingpin

Bein' a speedy kinda guy myself, I tend to build my stuff fairly similarly. 0-1* Toe, 0* camber (hold that thought) and 8-12* Caster. What I don't see in your list is KPI. I tend to build in about 10* KPI. You?

Have not done intentional kpi... meaning it is whatever it is. Must be pretty OK because it turns good both on and off road.

KPI is king pin inclination, I believe. Yep I just googled it to make sure. Caster is the angle that the steering pivots on from the side, kpi is the same pivot points but from the front

i know i probably won't beat there 500cc 4 cylinders off the line but hell, my 12hp turns some rpms hopefully i would outrun them with speed, although they may have a race with stock parts, i'll have to look into it

id leave it unlocked. high speeds on pavement could be disasterous. it would either hand-grenade or you would loose a good bit of steering at speed

Lock that sucker... traction! A well engineered frontend will perform wonderfully on and off road at speed. Being a go kart nut in my spare time (lol) , I can promise you that. Just remember that we are NOT talking about stock geometry here. It is best to fab a new front axle for this purpose.
