I just came back from Uwharrie,NC and I'm feeling a need for a four cycle bike. I have a FMF Fatty Pipe, Torque rings (at Mandifold and carb), airbox cover removed, 12 tooth front sporket, Vforce Ram reeds and am running 93 octane gas. The bike is a screamer, but when it comes to steep and rocking hills, the bike bogs down in the low end, while te four cycles just "chug" away. With the Four cycles at about par with the 2 cycles in weight, why not go with 4 cycle?
