Yes Mike, it has the closed system, it is still spotless after 70 minutes, the reason I mentioned the knocking when rich is that the instructions suggest controlling the rpm by richening the HS needle. Not possible to do it that way, the knocking is scary and real.
James, it sounds strong, when opening the throttle the acceleration is quick. This is an eerily smooth engine, I may stick it on an RCM 40 just to get it in the air.
When I get another hour on it I plan to install a 10 x 1 TurboHeader and see if it will respond like a Saito.
