Ok, this is going to stir the pot, but I don't care. I think its good discussion.. I have an RB racing dune ported, stock stroke 350. 35mm PWKs, 185psi, +4 timing, CPI inframes. This is my trail/dune bike. its nothing major, but runs good.
This past weekend, I raced a stock stroke A&S motor, drag ported on alky, and beat it every time by 3-4 bikes in the dunes. Same swinger length, and similar paddles. Similar rider capability.
Also raced a 421 cub from RDZ, and beat it every time by a couple lengths. I thought this was ridiculous, no way that should happen. The bike seemed to run decent too.
Now, I consider myself a novice rider, not a pro by any means.
I just thought it was necessary to give props to R&B about making good power, and big names aren't always the solution. Not that the other guys don't build badass motors, because I know they do. But, they got beat!
Not trying to toot my own horn here guys, but I have been layin it down to most similarly modded banshees that i race lately. I just thought it was a good enough sample to give R&B props, and to let you guys know whats up.
Now, begin the bashing lol
