So... how does that thing turn on pavement? Wondering if the added weight sitting 'on' the rear axle would hinder the opposing inner rear wheel from lifting properly. "If" turning is sketchy on pavement... at what points is it sketchy...? acceleration, deceleration, high speeds, upon take off, etc.

Turns exceptional well on pavement! At high speeds I try not to turn super sharp as say I would on dirt. I find myself almost trying to drift on pavement to off set the shift of weight of kart to outside of turn. Lack of turning the steering wheel in opposite direction has had me pointing the opposite direction a time of two on pavement. Of course slowing down always helps me maintain full steering but I like the edge of my seat kinda ride so I power the kart through my turns. The inner rear tire on rear axle on the inside of the turn usually lift. I attribute that mostly to the springs on my axles and maybe the 2 degree rear caster on the spindle hangers. If you are wondering if my kart plows through turns the answer is no not really. Kids yard kart as foundation + racing kart wheels and engine(s) + suspension of older off road kart (dingo 5hp) = wow factor!

Well... Im here to tell ya... if you have no turning problems... and you dont plan on giving rides... IMO, Id center your steering and seating. I found that it handles sideways momentum ALOT better. Right now, your CoG is to the left, which Im pretty sure makes turning right at higher speeds, a slightly higher adrenaline kick, when the right side of your kart becomes airbourne... LMAO (been there done that... Damage uncontrolled).

As far as spinning out, doing a 180*, easily... IMO Id say the springs travel is mostly to blame. You can compress the springs slightly and add washers, to stiffen the travel which will help add more tension to the springs as the weight is shifted to that axle, preventing the opposing rear wheel from lifting 'too' far it should help making drifting(on pavement) more controllable. Another thing that helps is proper Ackermann, which is a simple bolt on/addon.

What gearing are you running? You 'do' realize... w/ ~20hp... you 'could' gear at 3.5:1 and do ~50mph w/ little to no clutch burnage.

Hi Half-breeder, thanks for your thoughts! I know you prefer the steering in the center of your cart. While its more functional purposes described above not necessarily for me. I do plan on giving rides in the kart, I think!? Well eventually going to let my son ride shotgun with me.
The gear ration now is clutch 12 tooth and drive sprocket 72 teeth. I pulls really, really incredibly hard right now. I like it! My thoughts during build was low gearing for maximum torque to the ground through rear wheels. Wanted, and have achieved both rear tires losing traction and spinning. In the future I promise to start a thread on the speed of the kart.

Thank you MancoGX390! I am very honored! Such a privilege to share my build with all the great people here. Kart turned out awesome and winning the build off makes it even more sweeter!

Congrats.....that is so cool.....I honestly....did not vote for you.....I liked another build a teeny.....teeny....teeenyy. bit better........

And you were ahead.....so I didn't feel too guilty.....kinda like when the opposing football team comes to town.....with a hometown quarterback.....you gotta root a bit for him.....want him to do well....but lose in the end.......

It wasn't an easy decision.....and much like that football analogy.....it's almost backwards.....as I really liked his build....but was also pulling for the hometown.......as the difference between the two was strictly purpose....not quality of build.......

Again...CONGRATS! !!!!
