WHY?! short inlet timing 50degree and MASSIVE BLOWBACK?!? how does this go along with the explanation long inlet timings = blowback problems?!? other reasons? yes! see it compared to 2 healthy engines: original 200 freshly serviced with also only 50degree and a polni 218 with 75 degree race longstroke crank, both of course WITHOUT BLOWBACK = healthy engines :)
