Percentage is a weird way to describe this - Caster and Camber are always given in Degrees. How many degrees of induced negative camber is the positive caster giving you while turning? Enough to overcome the usual positive camber of beam axle designs?
Basic geometry , your kingpin should be angled toward the bottom of your tire for scrub and your tie rod pickup points on your spindles arms should be angled pointing to the center of your rear axle ( look up Ackermannn geometry)
What spindles are these? I'm currently of opinion that scrub radius is important. It plays a big role in how much the road can jerk the steering wheel around. I think most cyclekart builders are ignoring scrub radius, but I can tell from videos that their steering is being pulled around by very little bump.
The spindles in the video are Azusa spindles. You can get them off amazon. I have played with a few things with the front end and the 2 major things is Caster a Ackerman. Ackerman has is the angle of the steering bracket to the center off the back axle. This makes the front wheels turn in a way that the inside wheel, in a turn, does a smaller circle then the outside tire. It eliminated scrubbing. I have a video I am working on to show this.
Is this meant as a joke... I think it is. I did know the adjustment was needed but had no idea what would be enough. These thin tall tires kind of change the thinking on everything. A Cyclekart is the worst handling "race car" out there. i think that is what makes them so fun. This video was an attempt to make it better and really safer. Thank for the comment.
AZ CycleKart I wish I could say it was a joke XD. I felt like these old grand-prix-styled vehicles require much more drastic adjustments compared to modern cars, but I guess I underestimated the scale of the vehicles that this could affect!
It has to have a lot to do with how thin the tires. That small tire patch on the road needs the exaggerated adjustments to work right. I did learn a ton fixing this yellow Ford cyclekart.
When you describe a road or a roof slope , 100% equals 45°... (exemple for 1 foot distance you move up 1 foot) so when he says 10% I presume he means near to 4.5 degrees......

I took Jon's advice on my last CycleKart and increased the Caster to 12 degrees. The steering is much improved over previous build.
What was the previous angle of caster? I've read on the forum about 6 degrees is fine. Is that not enough?
@@paulmichaud3230 Video showed the pin inclination to be zero degrees, it would have been close to shopping trolley nervous. :D
Muchas Gracias, me construyó mi Cyclecar con el fin de viajar de México a la Patagonia Argentina tu video me fue muy útil. Saludos

Nice job, I didn't realize that angle would make such a difference.
Huge difference. Just slot of work to fix it after the spindle was welded on. Better to get it right the first time.
You must mean degrees, not percent.? (Lets not confuse folks were trying to teach) ;)
Yeah , because 10% of a circle is 36 degrees............big difference....
And we're not sure he means 10% of a whole circle, or 10% of the 90 degrees from vertical to horizontal !
Degrees not percent! Units matter!

Olá sou o Eduardo, moro no Brasil. Executei está angulação de caster e ficou maravilhoso. ✌️👍🙋♂️
While you're at it, increase the inclination of the kingpin to reduce scrub.
pluss it gives it more lift especcially on dirt.
can i just buy a fineshed front end?
Yes .. Renegade Karts
where can i get wheels?
Honda postie bikes :)
Are you still racing?
Who knew alignment adjustments could help so much on a cycle kart?

10 to 15% of what? 180 degrees?
