KZ1 would be fine. I don’t think they would walk away with times by any means and I’d like to see that question answered. A lot of it will depend on the track’s layout as well. Consider that in the 90’s 100cc karts lapped pretty damn close to open FC gearbox karts on tight tracks. Take that 100cc, add power while keeping weight near enough the same (very doable) and you’re right on the money.
I think that’s what will make it interesting. There’s all kinds of interesting karts out there too. Like CR250’s, with the gearbox cut off, running methanol, dual 135cc C-Open karts from the 70’s with 70-90HP on tap and so on.
So let’s see how they actually stack up, rather than guessing. Build some interesting stuff, have some fun and see what happens. Twins vs singles. New vs old. Light vs heavy. Shifter vs single gear etc etc.
That, plus every initiative for low-profile competition should be encouraged. But it would not be for me because I drive karts that are too slow anyway.
This reminds me of that FSA on a modern frame idea I was talking about earlier in the year. I only weigh 145, so I’d barely make junior weight as it is, which already gives me some of an advantage. If I could afford it, I’d definitely try something but for right now I’m stuck at Yamaha budget
Main difference when they were raced was that FSA ran a 30mm slide carb vs 24mm butterfly. Also you could run 6", non homolgated “fancy” tires.
Until 2001 (I think) FSA was also rotary only.
But otherwise the basic motors are the same, bar some tweaks to make them work best for a given track with the 30mm carb.
Are you familiar with Italsistem? They make FA engines for like $2,000 and I thought I might want to save up for it for fun sometime, if they’re any good at least.
Yeah they were world champions a couple of times I believe. I ran an MV21 for a while.
For $2000 though it’s just as likely to grenade as one that costs $900, so you might as well get a $900 one
True, it’s just the first one I could find. Used ones don’t seem to pop up all that often from what I could find, and searching Formula A for sale only gets me Briggs World Formulas
That’s awesome!
You know, I haven’t quite nailed down the formal process yet. We could have folks attach files to replies on the forum for now until I get something built.
Make sure you take all the pods and un-needed bits off. Get that frame nice and light and agile.
Also FSA you could effectively do anything inside the engine as long as it stayed 100cc (may have been a head volume limit too). I don’t think they were forced to run rotary, it was just faster until the changed the port height limits for reed engines in what 2000,01?
I might have remembered that port height thing wrong.
