Re-gearing - beating a dead horse?

[4 Paws_imp]

Sorry to re-visit a subject that apparently has been beat to death, but I am.

Interested in a bit taller gearing for my 2013 5 speed, would like to drop the rpm's a bit while cruising along.
I've done the forum searches and read as many existing threads and postings as I could find multiple times and am a touch confused as to one item - if I increase the countershaft sprocket by one tooth do I need to modify the sprocket cover to alleviate clearance issues - grind away to make more room?

Does changing (reducing) just the rear sprocket by two or possibly one teeth make any appreciable difference or is it pretty much just spending money for the pleasure of spending money?

There is a guard (not the cover) that needs to be ground slightly from what I understand. Personally if I were going that route I'd just do the front sprocket and see how that is before considering a rear sprocket. With a front you will not have to alter the chain, with a rear you might have to shorten the chain, grinding off the staking link, getting a new staking link, and staking it.

Here is one thread you may find interesting

You might PM or email PekingDuck. CB4ME and Chip Beck who have all changed both sprockets for first hand info

Above is a thread with additional information.

No need to shorten the chain going 19-38's final drive

Five minute job with the guard in a vise using a grinder.
