This site contain information and links for the good old smoky
Yamaha RD350 and the TZR250 type 3MA 2stroke motorcycles.
At the moment the site is under construction.
I have posted some information on the ignition modification I’m working on
and the removal of the air restrictions on the Japanese TZR model.
Check it out. It is located under the TZR250 3MA menu.
