yeah will be watching, I was more surprised by how high they were winding the engine 7900 RPM
Being an OHV architecture, that is Screaming
Uh, å¾¹HV? Over Head Valve? Has anyone built an Under Head Valve in decades? Does even Briggs & Stratton still make an UHV engine?
Honda has made many pushrod engines with 10,500 RPM redlines.
RPM is mostly meaningless. The rate a shaft spins or piston reverses direction isnç¨š a primary indicator of what some would have you believe. The real issue is with piston speed. The faster the piston the greater the wear per inch the piston rings travel. So long stroke engines run slower but may have piston speeds comparable to supposedly å¡—igh stressed high RPM engines.
