It's a yes and no. It depends on rather your bike was running fine before you did the swap. Also on jetting, ignition timing, moon, ect. How fast did the bike go before? What is the speed rating on the frame, did it go at least that fast before? If it is a 20mph, then don't expect better performance, in fact you might have been better with a 12 on the super slow cylinder. What do your plugs look like? Is the Variator operating properly, clutch? Lot's of stuff that need to be checked before you go blaming the del and short intake.
