If I've got one pet hate (uh no, I've got heaps actually!) it's listening to a bike screaming away in top gear when your travelling long distance. Even worse if your slip on is too loud Ha ha.
I've decided the N400 falls into this category after a long ride today on mostly straight roads. At 120kph/75mph your sitting on just over 7K RPM, too much IMO and it makes your fuel economy suck too.
So I've decided to change the final reduction ratio from 2.93 (41/14) to 2.71 (38/14). I could also go to 2.73 by adding a tooth to the front sprocket which is close but I don't want to bring the axle any further forward in the slot.
Better to drop three teeth off the rear sprocket which is basically raising the gearing by 8%.
This should make my speedo read more accurately too as it's a bit optimistic. I can tell from the speed radar advisory signs we have here.
I may need to take a link out of my chain though.
I'm going to get a 38 tooth 520 blank made out of aluminium and I will machine the center out to suit the hub diameter and drill to suit for sprocket bolts.
Does anyone with a Ninja 300 know if the front sprockets are interchangeable?. This would be really handy info to know. Rear as well.
