Ok, I put a cam and a .o40 bore kit on my bike. 1st and second gear are gone so fast, that I think I need to change from front or rear gear. What do you all suggest for drag racing?

cnl83, stock gearing is different for different years. Any idea how many teeth you're running? What year machine do you have?
