back then, 80, 81, 250s were advancing very rapidly....C ('77) monoshock TZ chassis, B model cases, Kanemoto ported F top end, 38 Lectron's, and cut B pipes (attrocious pipes, I might add). My old F (79) was hot for exactly 1 season. The Gs got separate cylinders still parallel, but with base bolts The F had head bolts running through the cylinder on the RD pattern which greatly restricted transfer port area. The Gs also had the first power valves. The G was a great advance, then the cylinders got Veed and the G was history, LOL!
OK kids, that concludes today's lesson on the history of an extinct form of roadracing. Tomorrow we will cover record players, the predecessor to the CD.
