Basic Stage one Engine Design
What happens when your cash outlay for a Stage 1 engine is
under $150? If you have done your homework like Brett Jacobs, you don't give up any
performance. Here is an excellent example of low cost and good power. Brett and C&H Motorcycles in Spartanburg, S.C. deserve a lot of credit for a great job
of tuning.
Brett's Comments: My Fatboy now runs
awesome and beats in a drag race a few of my friends that spent over $1000 on their EVO
and thought they were bad asses. :) Their jaw drops when I start to pull away from them at
a red light. They think I'm lying to them and have a cam installed. Haaaa! What is even
funnier, my total cost was $140 and a few hours of my time.
YOU ARE THE MAN!!!!!!!!!!! Thanks again.
Best Regards, Brett Jacobs |
