I changed my front sprocket at the same time I added the mini-tach. I notice that with the 19t I do 70 mph between 3900 and 4000 rpm. I'm just wondering what difference folks with the 18T are getting.

I've had the 17, 18 & 19, at one time. I currently run the 18T, at 4000 rpm's I'm doing about 67 mph. I would have moved back to the 19T until I replaced my rear tire with the 140R80. Going from the stock 130 to the 140 and keeping the same aspect ratio made the tire taller than the stock tire, which raised the final drive ratio a little more. So now I figure I'm at 18 1/2T. Really like the lower revs on the highway.
