So I can find a 65 tooth pulley and swap it out, no changing belts or anything else, that is if I can get the correct tension, if not it is a mute point if I have to change the belt because I could just change the trans pulley up 2 teeth from 32 to 34 to reduce my rpms.
GRBrown, I have had this bike for one year, I have put almost 20,000 miles on it, I live in a rural area in Virginia and am in 5th gear most of the time, on the highway, rt 95, rt 66, rt 81 and more, if I am going 65 I will be run over, my bike feels and sounds much happier between 2,600 and 2,800 rpms instead of 3,000 and above while cruising long distances. Most of my group have 6 speeds and like to cruise at 75 mph, we did a trip to Mississippi last month, 2,300 miles round trip, I rode one of my friends 6 speed, he rode mine, after we switched back he told me I need a 6 speed. I said I am going to fix that for much less then a new 6 speed, I am not interested in how fast I can come out of the hole, or how fast I can accelerate, I want to reduce the buzz and be comfortable in 5th gear cruising.
Thanks again

Take a look at typical dyno curves for our bikes. The best part of the torque curve is around 3,000-4,500rpm. That is where your bike will be at its best. Do try it! You'll leave those pesky 6-speeds in your wake.....

I understand, I want to keep my race car at maximum power and rpm while racing, but while cruising I want my bike to be in its comfort zone so to speak, not at 4,500 rpm's. How long will a Harley motor last a 4,000 rpm's for 2,000 miles, not as long as at 2,800 rpm's, and as a matter of fact either will I lol

well,
my evos are up way over 75K and much of the time is over 4K (85 mph ish w/ stock gearing)
the flip side of the coin is the guys who lug the motor and destroy the bottom end.
you can determine what you wanna do, I've told you what I did on 2 of my bikes, but I rarely ride under 2800, more often 3200 or more.
among other reasons, this allows me to decrease speed by closing the throttle- in canyon riding, this saves the brakes for when I need them.

I understand what you are saying, if I need more power I simply down shift to go up a hill or thru a corner, but out on a open straight mostly flat road the bike feels better at about 2,800 rpm's, I don't think that is lugging the engine, my car runs 2,500 rpm's at 75 mph and if I need to pass or go up a hill it down shifts as I press the throttle down same as I would down shift to pass or go up a hill on my bike, I think reducing the rpm's about 250 at 70 mph to around 2,700 would greatly inprove ride comfort and reduce the buzz, will let you know how it works out, if i don't like it I can easily switch back, is just a matter of pulling the primary and replacing the comp gear and chain, thanks for the input guys.

FWB,
Your absolutely correct, 2800 rpm is not "lugging it" for this engine design.
Less than 2k is.
I also agree with you concerning the comfort factor of using lower RPM's when the situation and conditions allow.
I live in your area and understand the conditions that you ride in.
I use earplugs when I ride and still enjoy the lower RPM's when cruising on the interstates.
Keep the dirty side down.
