can you just swap out the gears from a 1300 to 1800 in the final?
You would change the gears and the housing. Its a unit. You can get the parts(gears) separately from the dealer. But then you have to setup the ring gear and pinion gear. The pinion depth to ring gear takes time. So find a housing unit. Its complete with the gears.can you just swap out the gears from a 1300 to 1800 in the final?
Yeah, what Poison said. I love it, but on the highway, you feel like you should have another gear left. I'm only getting about 30 mpg with it. I have the speedohealer and my speedo is dead on, my odometer is 3% off. Not bad I'd say. My speedo was 19% off before the speedohealer (that's also with a 165/80R15 cartire which threw me a little off too.)I've used my gps to compare gas mileage and actual speeds between the 13 and 18 final:
Cons with the 18 -
Worse gas mileage
Speedo way, way off
rpms seem very high on highway, and I never really considered the 13 final bad in that regard.
It is very fun for hitting mountain twisty backroads though. If you do a lot of that type of riding - you will probably like it.
If you are already complaining about the bike needing 6th gear, or do a bit of highway or long flat straight road riding - you probably won't like it.
Top end really isn't affected, though the bike will be screaming.
