I could care less how it looks, you could play with the exhaust on that thing to sound wicked
Id be ok with a kohler twin.
Good luck finding a clutch or cvt rated for the torque though.
But do it!!!!
Ill go one better here: if we all get these things done by spring, i will find us a place to meet, race, and feed lunch. On me. Maybe even do it as a large scale meet and greet for the tri state area. (Nc,sc,tn) virginia would be allowed, but only if they bring fresh clams from the Chesapeake bay.

I think that a DIY Frazer-Nash 'chain-gang' style transmission would be perfect for the spirit of the event.
Admittedly, this the independent engine and CVT is one of the reasons I'd lean towards building a Morgan 3-wheeler using a GY6 (clone) all-in-one engine/CVT/swing-arm from a scooter and tuned to about the same 10-11 hp as the unencumbered GX200's in the cycle karts are claimed to make.

What do I have to bring coming from Kentucky?
In reply to Chadeux:
Mountain oysters
In reply to Dusterbd13:
I'll see what I can do.
In reply to Driven5 :
Depending on where you live there are growing groups all around the world. Here in Arizona we have two events scheduled over the next two months. Sept 2 and 3rd in Boulder City, NV and October 21 and 22nd in Victorville, CA. Both these events are at organized race tracks. The Nevada event will be at a paved 1/5 mile oval track, the SoCal event will be at a paved .7 mile race coarse. We are adding new events and finding new tracks all the time that are happy to have us come out and play.

So make it both wheel drive/live axle, and set it up correctly
In reply to stevev:
are there particular rules that must be obeyed (and a link to said rules) or is it a spirit of the event type thing?
Would electric power be appropriate?
I’m bumping this.
I’m late to the party, but see that procrastination is the standard fare, so I don’t feel too bad.
My youngest daughter is the last one in the house, and totally into this idea (and not really into building a Challenge car).
I’d say, that means I HAVE to build one this year.
Plus, I now live in SC, so I can be in the club! Duster, I’m holding you to it!
I’m building one for 2019. Perhaps several.
I’d like better rules, but don’t really care. Editorial fodder for the magazine will be sufficient.
The “Spirit of the CycleKart” seems to be a little different than the “Spirit of the Challenge”. They are much more about visual appeal than speed. I’m good with that (but doubt some of you can do it!). If we take speed off the table for 1 year, we’d have a much better chance at good editorial content, and less insurance liability hurdles. Seems like a good start.
Who else is in?
I'm in but procrastinating as well. I've ordered some parts but made zero progress. I was going to try to 2018 but...
Also, if there is enough interest for 2018, I'll try to pull something together ASAP.
I am down for giving it a shot in 2019. 2018 isn't happening for me....
also tentatively in for 2019. Already thinking about using it as a 'test bed' of sorts.
I found the following general guidelines - yea or nea?
Cyclekart= A one-seat car using Honda 17"x 1 3/4" or 2" rims, 2.50 x 17" tires (2.75's have been used on the Alfa), a 38" track, wheelbase as close to 66" as the aesthetics of the car will allow (err on the shorter side for more abstract cuteness and general attractiveness), weight no more than 250lbs , and powered by a 200cc, single cylinder, 6.5 hp Honda OHV engine (the GX200). A Cyclekart should not cost more than $1750 to build in 2001 dollars (this is to avoid spending races where people start hiring out parts and making things too nice; we're not making show cars, and an element of scrounging adds to the fun).
Some measurements:
Max Length: 98"
Max Width: 40"
1"X3" steel framerails (84" long in the Type 59, rear axle 10" ahead of aft end) The 1" X 3" steel stock comes in thicker and thinner walls; we use the thinner 1/16".
Front springs 24" X 1 1/4", 2 leaf 1/2 elliptics
from: http://cyclekarts.com/CycleKartSpecs.html
I think we should simplify the above to:
The wheels are going to be the tough part, and I would say take whatever the popular budget cap is and add $150 to it so we can just specify a new Predator 212 and centrifugal clutch and be done with that part.

I think we should simplify the above to:
- A single seat car built by owner (not bought) with fun and aesthetics as the goal
- Max Length/width/weight/power/cost 98"/40"/250lbs/6.5HP/$challenge budget
- Approximate Track/wheelbase 38"/66"
- 2.50x17 tires? (I could go either way on making a 'spec' tire size or not)
I like that, but I would nix the spec tires. Limits creativity.
I would also put the budget lower, if there is gonna be one.
What are the competitive aspects? Will it be “Concours” style judging, or also have a speed or handling component?
Some go-kart hubs have a 4x4 bolt pattern. It's close enough to 4x100!
I'm ok with no spec tire size.
I think we should find a way to do a speed and handling component. Like maybe a "24 minutes of cyclecarts". 24 minute endurance race format, everyone starts at the sound of a cap gun and has to run to their car, start it, get in and go. Maybe make a simple track in the dirt and grass parking area. Contact would be strictly against the spirit of the event.
Or like I said earlier do a 'top speed' competition, since many cars back then were rated by top speed instead of acceleration. Make a large circle with a leg (basically the shape of the letter "P"), let everyone have a lap or two around the circle and then exit into the leg. Use autox lights at beginning and end of the leg (so you only measure time as the cart travels in a straight line maybe 50-100 ft), shortest time wins.
In reply to Robbie :
I’m good with either of those.
I don’t think GRM or the NHRA will allow it on the track property. It’s a liability issue, that would kill the idea.
Other ideas?
Hey gang, I appreciate your enthusiasm, but I think we need to have at least one eye on the safety aspects. The high CG, the fact that our autocross is on pavement, and the lack of roll protection have me a bit concerned.
Sorry to be a party pooper.
I say Concours only, but the vehicle must move on its own power.
A couple of “parade laps” through the Autocross or dirt parking area for the photo ops would be great!
Maybe we can find a nearby farm that would let us try some 3/4 vintage style rally cross (unofficially!)!!
