KTM & Husqvarna have overcome the technical hurdles, & are releasing 2-stroke EFI engine off road bikes this year. A primary motivation for this evolution is that the engines must meet impending Euro 5 emissions regs. Again, these models are marketed for off road use.
So, if Euro emissions laws apply to karting as well, does that mean that EFI is eventually coming? I’ve heard that TM has a prototype in the lab, & there was a Modena EFI prototype displayed back in 2014, but it never came to market.
I’m aware of that kit, but it doesn’t meet the Euro4 mandate, which is the driving point of my question. If emissions mandates will be applied to off (public) road vehicles, of which karts are a subset, then are true 2-stroke EFI (ie. case & transfer port injectors) engines inevitably in the future of karting?
Hmm, I sure hope politicians/regulators don’t start considering karts as “off-road vehicles”, as opposed to pure racing vehicles. Please don’t encourage that line of thought! 🙂 It could be very dangerous to the future of karting.
I think being afraid of change to modern solutions which are well-proven, and well-documented pose a threat to the future of most things – karting very much included.
Think about it, no more carbs with 3 jets, various needles, and knobs. No more carb rebuilds. That sounds wonderful! More driving and less cost messing about and having to have $300 in carb-tuning equipment to be competitive.
Not about being afraid of change, just not wanting some bureaucrat dictating the terms. I would personally love to see a good fuel injection package for karts, but don’t think I want it designed by a lawyer. Cost IS a factor here, mass market emissions specs could well kill the whole thing.
