I also want to change my final drive ratio and lower it a bit. Stock (for an 04 Daytona) is 42/18 which is equal to 2.33.
I also wanted to try to stick with an 18 tooth countersprocket--- for two reasons--- one to lessen the likelihood of wearing the blocks and secondly because an 18T should have longer life than a 17T.
And it would make me use a larger rear sprocket--- which, again, all things equal--- should give longer service life.
So--- I've been kicking around going with a 46\18 which would lower my final drive ratio to 2.56.
The other day I did find a vendor (but forgot to bookmark them) who offers a 46 tooth rear sprocket for my year daytona. I if remember correctly--- they even had the 46 toother in alum.
2.33 to 2.56 is only about 10 percent lower. What I am looking to do is to raise my rpms at cruising speed so that I can use 5th or 6th gear.
This past summer on a long road trip I found that to be in (I forget exactly) 5th gear at about 6000 rpms I was running close to 80 mph. Which in shark infested waters--- I wanted to back off a bit but found myself running in fourth gear to keep the r's above 5K while maintaining a road speed of say 65 to 70 mph.
So--- I'm hoping that I can (if I drop down to a 2.55 ratio) be able to kick into at least fifth gear and not be lugging the engine. My bike really doesn't like running much below 5000 rpm's. Does this sound right to you guys?
thanks,
Mike
