Yamaha RD400 Race Build- 65 HP

Sharing my build of a 1976 Yamaha RD400 full race engine.
Techniques shown include engine assembly, measuring port timing, carb build, expansion chamber exhaust design and fabrication, dyno test and more.
The RD400 is a long stroke version of Yamaha's RD350 two stroke. The same tuning techniques can be used to build a RD350 race engine and exhaust.
This is not a full tutorial on everything involved with an engine build. It does not show final jetting or proper operation. Air cooled two strokes require precise jetting to allow full power available and not seizing or detonating the pistons. The life span of the pistons is short compared to a street engine.
Motorcycles are dangerous. It is th...

Ducati 250 Racing Exhaust- Megaphone Fabrication

Просмотров 5 тыс.6 лет назад

My fabrication of a racing megaphone exhaust for my 1968 Ducati 250 single. The meg is 23" with a straight through perforated glass pack core and reverse cone end cap. Fitment is to a 1-1/2" OD headpipe by slip fit sleeve and springs. Excellent power, and barely legal for AHRMA vintage roadracing.
