hummm - have a quite early '95 (built in late '94) and a '02 - might should move the tach and see if the different 5th is indeed different ratio

Please keep in mind that the sprockets are stock, but the tire is not.  It is the next size larger 140/90-15 which has a diameter of 1/2-3/4" larger than a stock tire.
Instead of a circumference of 77.5", the stocker is going to be about 75.9"...depending on manufacturer, because they do vary in size.  Anyway, that works out to a hair over 2%.  Only 120 rpm at 6000.

Greg, my bike only had 100 miles on it when it got the Jardine muffler,152.5 main,55 pilot and KN drop in filter, and no mod needed to the white spacer cause it pull like he11. Pilot screw out 1and1/2 turns. No backfires just a nice crackle on decell. The first thing I do to every bike I have ever owned, including my first bike,Honda Sport 50, was to put a pipe on and rework carb and make it breathe, once that was done I played with the gear raios to suite my purpose. Some bikes I even had whole tire and wheel/sprocket assemblies set up for a quick swap to run trail, or run the street, just like I did with my hot rods. It now has 2000 miles on it. It pulls trough town(25MPH in 5th) with no need to down shift to have plenty of accel once it is out of town., but like I said it is screaming bloody murder at 80MPH and wide open , no throttle left, it's done. ELFINE. NADA.  
  ALSO, for every tooth you add or subtract off the rear sprocket there will be a change of 2.5%. I added that to the two charts on the first page so the info is all together.

Hey greg, where you located? I graduated from Tigard High right near there. Used to drive past Bob's all the time. Now I am on the face of the SUn in Phx.

sorry we can't afford any it's been cold here... it was only 90 on Sat   .

I don't know.  Since you only have 2000 on the clock, did you ride it like that during break-in?  

Do you have complete throttle travel?

AND, as I said in the previous post, you'll need a GPS to see that change in speed, anyway

Broke it in easy, in stages up to 1000 miles, then just drove like I normally would. I checked throttle travel, I even checked to see if the brakes were dragging.or the axles were to tight and pressing the bearings to hard. You name it, I checked it. Bike is even lighter than when stock and I only weigh 150. 80MPH that's all she wrote.
With the 17/45 sprocket it works out to a 10% change and if you can find a 44 rear it would be a 12.5% change.
