can a yamaha dt 125 beat speedfight 100cc mine will go 50mph is there any tweeks u can do 2 make hit 75-80 mph
Dt125 will piss on a speedfight all day long! If you own the dt, then you need to derestrict the clocks which is a wire that needs to be removed and earthed Full dep system Derestrict airbox 240 jet in the carb and sprockets to suit
Seeing as this is a scooter forum I expect he was talking about making the speedfight faster. In short no. For more people saying no and other information use the search.
