yes i read what you posted.. and i was addressin' this...

you're fighting a losing battle dumpin' money into an f2motor to achieve comparable horsepower/torque to modern 600s.

find other ways to lower your laptimes...like jason's suggestion on attendin' a school... or if u would like a part for your bike.. the best mod you canon any track bike is aslipper clutch, you can make uptime on corner entries by having one.

but it's your bike, do what makes happy.
