[b]Timing and tips on a Stroked Engine.[/b]

I have a 2001 RM 125 That I had the Crank Stroked on. Does Anyone know if This Will have an effect on the Igniton Timing of the Bike??(Say I left it in the Stock Setting) Also, does anyone know how to figure Blowdown duration from Degrees of opening from exhaust to the ports?? Also, does anyone have any advice on Tuning This Engine?? I'm trying to learn as I go and do everthing myself.  The only thing I haven't done is balance the crank,(didn't have acess to a balancing machine. Any help will be appreciated. I'll post all results I get.
       Thanks
