RE: OS have just announced a 55cc gas engine
the ignition is an in-house design, they didn't use any off-the-shelf design. Apparently it is optimized to maintain high voltage and high RPM.
Looking closely at the con rod I think that is a bushing and not a needle bearing. Ruh roh, chink in the armor! Just like the Moki 1.80 gasser.
As for the price there is no telling what will happen there. Most of the time the OS engines sell for around 70% of retail price, so maybe $450 or so?
**edit** on second look, it almost appears to have needle bearings at the crankpin side. If they went to the trouble of designing their own carb and ignition, I can't believe they would forget the needle bearings.
