It isn't a MUST that you change then. Going down in the front or up in the rear will give you more acceleration, but less top speed, bigger in the front or smaller in the rear will give you less acceleration, but more top speed.

A popular combo is -1+2 but it all depends on the kind of riding you do!

So you will advise to go 1 up in front and 2 down at the back. Will it be worth while on top speed?

That's gonna hurt your acceleration a good bit, where are you gonna new to go more then 161mph? Lol

i used to own a R1, so if the top speed will improve it is a plus for me. I know I will never get top speed of R1 of course. Not that much worried about acceleration. Do you think top speed will improve and by how much? Thanks for advice

No. He means the other way around. Minus 1 in the front and 2 up in the back.
Why would you change your sprocket off 'some guys' advice? If you don't notice yourself that you need a gearing change then you probably don't need a gearing change. If you're insistent on trying it then just go -1(that's 1 down) in the front and go from there.

You can use this chart here to see what the changes in gearing will do. Next time just use the SEARCH. http://www.gearingcommander.com/
