Default Sprocket change - mph higher or lower?

ok, it's time for new sprockets and chain on the '54. I plan on doing a +2 in the rear, or maybe even a -1/+2 setup with a 520 chain. I've heard bad things about Vortex sprockets so i think i'm gonna go with the RK 520 Chain and AFAM sprockets. Is this a good setup?

Also, i was wondering about my speedometer, i know it's going to be inaccurate but my question is will it read higher or lower than my actual speed after the sprocket change?

for example, if i'm actually doing 50 by gps will my speedo read around 40 or 60?

Also, what kind of percentage in an inaccuracy can i expect after the conversion? 10%? 20%?

Thanks in advance guys!

RK is an ok chain, afam is also decent sprocket.
It will read higher, 50 on gps will be 60 on the speedo
If i recall correctly with a -1+2 it will be around 13%. You could get a speedo healer tho.

In case you may ask i use Driven chains and sprockets. They cost a bit more but you get what you pay for

^^^
dido ... i have always run RK chains and Vortex sprockets. I have never had a problem. Personally, I have always thought they are the best looking set-up as well.

BUT THAT"S JUST ME AND MINE

Yea i have heard a few bad things about Vortex, but honestly it seems like its from guys who dont take care it. Cleaning, lubing, proper adjustment, etc.

I run the 15t, 45t set up in vortex sprockets and RK 520 chain- never had a problem. Just maintainance them and yer fine... BTW the -1/+2 gives you a perfect 1-3 ratio, which is the perfect combo track and street. Trust me it RIPS.
