i have a 2002 honda shadow spirit 750. it gets pretty buzzy/shaky over 65 mph. im looking for a faster n better quality highway ride. i want to change the gearing for better highway speed. any thoughts or suggestions would be appreciated. thanks.  

HI; I think you should call Honda and ask if they make smaller or bigger belt drives. One for the trany output and rear sprocket. That is how you would change the gear ratio.
Most V twins are a little buzzy above 65mph. scruffy...  

hey scruffy its not a crappy harley. it has a countershaft sprocket .im looking for # of teeth. stick to what you know mopeds.  

PITY Scott. If it was Belt or chain, you'd have a chance at a better ride.

I don't know of any sites that make gears for shaft drive. It changes the angle of the driveshaft depending on the number of sprockets on the final, just real messy.

While shaft is nice if you like the ratios it give you.. it does in turn give you the shaft if you don't  

doesnt anyone have a clue? its not shaft driven. honda didnt put shaft on shadow spirit till 2007. it has a counter shaft on trans and rear wheel sprocket. thats it. i want to know # of teeth to achieve better highway ride .a larger bike is 9 grand .2 sprokets are 100 bucks.

So, just to fill in the pieces:
You likely have a 44 tooth rear sprocket.
I saw countershaft, and read it as shaft and that was the only context that it made sense to me since you were talking about final drive ratios.

What you  want is a 42 tooth rear sprocket, like this

It should pull your RPM down by close to 10%
