Good luck with seeing that everyone plays by the rules.
MONEY - Tuners that know what they are doing - and the very best riders..

Maybe its because the factory bikes are blueprinted. The factory has a parts room full of parts and can build each bike using only the best parts.

another rule applies here also - its called don't over modify.

way back in the 70's when I started racing. I raced an RD350 yamaha
we had 3 basic classes to run them in
1. production where only changes allowed were tires, rear shocks, handlebars, gearing(sprockets) carb jetting, and rearsets.
2 cafe class where anything goes as long as the bike remained street (somewhat) legal.
and
3 GP anything goes this was the Yamaha TZ full roadracer class.
I always did better in cafe class with my production RD then the guys with the modifyed RDs.
