Gonna run the Predator initially this summer with the stock carb.
But....once I've got the bugs worked out, I'm just gonna have
to mess with the motor and bump up the pony power a bit.
I've been reading on the gokart sites and it seems like they
are all over the place as far as which model Mikuni carb
they're choosing. Most of the suppers offer upgrade mod
packages with the 22mm slide carb. Is the slide better
than the barrel?
Of course a lot of factors enter into the choice, and they
mostly involve how much air your engine is capable of or
is going to gulp.
Have any of you guys experimented with them on a cyclekart
and what were the results?

I haven't messed with the carb nor will I, but a sure like the idea of a top load cable. Beats the heck out of what we're doing now!

I've been debating on a Mikuni carb, I think it would look better, and I've heard they make the throttle response better while adding a little more power. Not really that I need more power, as my brakes are already having a little struggle stopping the kart. But then again, it's not like I'm having any problems out of the stock carb. Did you decide to go with the Mikuni?

The ONLY reason I'm not running an M22 setup already is that the G'ville guidelines don't permit it, and
I don't want to swap back and forth.
I guess we'll see what the future Brings.

Exactly what I didn't know way back in Apr 7, 2016 Dave, when I
first posted this thread. Of course back then I was envisioning
the possibility of a modified class if there was ever to be a
genuine sanctioning body formed.
If you're planning to just beat around your own pea patch Brian
and not play with the other guys, then go for it. That would be
a definite improvement over the stock carburetor.
I'm moving forward slowly in several different ways with my ideas
of what a Cyclecar or Cyclkart should be. I won't be playing with
any one else, so it's obvious that this is for my own entertainment.
One will use a box stock 212 for the kiddies and ladies who care
to give a little sporty car a try. One will have a heavily modified 212 Hemi
and be set up to to swap with the 301 I have on the shelf. And, the last
one that's on the drawing board will have a 670 V-twin in a front engine
configuration. I picked the twin up this summer when they were on sale
and am gathering up ideas for the drive line. All will be patterned after
20's GP cars with roughly the same dimensions of a standard run of the
mill Cyclekart, but probably pushing the tread and WB to the limit or a
bit beyond.
Of course for all of that to happen I have to live long enough to finish the
shop to build them in. Then finish the cars and stay healthy enough to
climb into one and survive the beating.

So, I'm looking at the Mikuni 22mm carbs and I'm seeing prices ranging from like $30-$100 So what's the difference? I'm guessing the cheaper ones are knockoffs, but what would be the differences that would make them $100? Also, are there any ways of telling a real Mikuni from a knockoff? And am I looking for a 22mm or the VM22??

I'm putting a Mukuni V22 with Inverted intake on mine while its tore down...

I'm not to worried about rules, as my chances of hauling it to Tieton are slim and none... I'm building this one for me...

I'll probably never make it to Tieton either, seeing that it's over 2,500 miles away. Also, my kart is probably a couple inches too long and too wide to meet specifications to qualify. Although it would be a blast just to see everyone else's hardwork and problem solving. Let me know how you like the Mikuni setup. The only thing I don't know about is how I'd do my choke cable mounting bracket on a Mikuni

If you fatten up the idle jet circuit you wont need a choke. You might go through a few fouled plugs though.

Well, my front track is too wide for Teton anyway, and the AZ guys will either let me run with them, or they won't...

They are 3 hours East of me, so it isn't like I can just pop over there every time they run.

Bow, your always welcome. We have no restrictions on carbs. I have a mikuni set up from go power sports sitting on my desk. Our only rule is to have fun.

Much Appreciated Jon.

My plan is to have my CycleKart ready for Prime Time before the end of the year. I'd love to run next weekend, but I won't have it ready by then...

Next weekend is not a race. Just a day at the track. The track is really too small to pass on. So we are just doing laps. If it runs bring it out. We let just chassis run too. Hell my ratrod has been only a chassis for a year.

Either way your welcome when you can make it.
