As a mechanic with more than 40 years in the<br />trades, I can tell you that "gryoscopic forces" do not even come<br />into play. All radial engines have an odd number of cylinders.<br />This is a conscession to balance. <br /><br />I own a 96 CI Harley Davidson. The engine in this photo is more<br />balaced than my twin cam V-2 but that does not equate in any way to<br />centripetal forces! As a science geek at age 14 I understood Newtonian physics.<br /><br /><br /> Leonard Jonesnoreply@blogger.comtag:blogger.com,1999:blog-4533651942397782565.post-57209012846293765352018-07-09T18:43:08.455-07:002018-07-09T18:43:08.455-07:00This is not a scale model.

My resume includes air and gas<br />compressor mechanic, Millwright, maintenance mechanic and<br />electrician.<br /><br />My father was an air compressor mechanic. He once asked someone<br />which piston weighs more (a large LP aluminum piston and a smaller<br />cast iron HP piston.) The correct answer is they both weighed the<br />same.<br /><br />When it comes to radial engines, you will never find an even <br />number of cylinders. they are all 3, 5, 7, 9 or two banks of<br />odd number cylinders. It is all about balance. Only in-line<br />engines can support odd numbers of cylinders because of counter-<br />weights.<br /><br />I have worked on reciprocating compressors that were driven by<br />by 5,000 HP elecrtic motors. Starting with Ingersoll Rand <br />PHE's, these 2 cylinder compressors were horizontally opposed.<br />Their HHE's added 2 or three banks. Not one of them had counterweights.<br /><br />The most naturally ballanced engines or compressors are boxers.<br /><br /><br /> Leonard Jonesnoreply@blogger.comtag:blogger.com,1999:blog-4533651942397782565.post-40215276598211586502018-07-09T18:04:21.127-07:002018-07-09T18:04:21.127-07:00Here's the story on this bike.

It was a powerhouse compared to the Indian's and Harley's that had been dominating boardtrack. It had problems with exhaust heat, getting it started, and a gyroscopic force issue that made it a difficult bike to ride. tsquaredhttps://www.blogger.com/profile/02737130316088634658noreply@blogger.comtag:blogger.com,1999:blog-4533651942397782565.post-46887868858037231642018-07-09T10:37:14.854-07:002018-07-09T10:37:14.854-07:00Could be legit.
