does any body know how much horse power a stock Z 250 has. how much more power would it get fromm a 25 cc over bore (i.e 10% gain)

 

IM NOT TO SURE ABOUT THE HP OF THE SUZUKI, BUT MY LITTLE SIS HAS A HONDA 250ex AND WE PUT IT ON THE DYNO A FEW MONTHS AGO AND IT SHOWED ABOUT 17HP RWHP. YOUR SUZUKI SHOULD BE REALLY CLOSE TO THAT. ANYWAY HOPE THIS HELPS.

 

yea 17 RWHP sounds about right
