I just got my CPI inframes and clamp on K&N filters. Installed the parts to get ready for a dune trip next weekend. Re-jetted the carbs. I put 310 mains, 30 pilots, and left the needle in the third position. I fire it up and take it for a ride to see how it works. It seems like the low end is very hesitant. I know that these are mid to high range pipes but i wouldn't expect the low end to be worse than stock. Another thing it is smoking real bad like it is running rich. The smoke is blue. I drained my gas tank and put new fuel and oil in it 40:1 because my roommate borrowed the bike and didn't know what kind of oil he used to mix it. All he knew is that it is pre-mix oil So i tried to ride it for a while to see if maybe it would quite smoking but that didn't help. it is sea level here and around 65 degrees. Any suggestions would be appreciated thanks in advance.
