Actually reading further last nite about 2st and fuel injection, it appears that KTM, Husky, TM are all actively working on direct fuel injection.
It would be a huge boost for 2st in terms of emission controls etc and registration of bike, esp in the US of A, which of course is a huge market they all want to a slice off.
For racing it will properly not mean much, if anything at all, as a well tuned smoker goes excellent at the moment.
Possible some fuel economy will be achieved and less oil cost.
