Probably not, takes the same amount of hp to do 70 mph whether you are turning 5,500 rpm or 5,000 rpm.
For me a change to a 16T front sprocket was easier. For one thing the 16T is available from Kawasaki ((13144-0038). Kawasaki O.E.M. sprockets are first rate and it is hard to match their quality. Second, it is easier for me to change the front sprockets. Takes about 30 minutes.
The difference is with the 15/44 setup with the 15/46 you would be doing about say 5,550 rpm @ 70 mph true, with the 15/44 your rpm would be 5,308 and with the 16/46 it would be 5,203.
Downside is the 15/44 setup your speedo will probably dead on and the odo off a bit. With the 16/46 my speedo reads 68 and 70 (true) and the odo is 9% short.
