do i have the corect prop ?????
my mods 2009 Fzs ,R2,C3 ,riva pipe, filter ,rive power color 13/24 ,R&D intake Grate,R&D ride Plate.
my speed was 72Mph with full tank , RPM 7450.
i was thinking to change the prop to 13/23 will i get more speed .
my brother fx cruiser same mods but with stock ride plate and the new double prop << his speed was 71MPH ,Rpm 8100
what do you think guys

Right now you might as well not even have the R2 because you aren't taking advantage of the added RPM. 7400 is lower than stock. You need to get them up to around 8400.
I'm running 77 with the stock boost wheel. With you running the C3 and R2 you should be over 80.

i had the r2/c3 with a 13/23 skat.
more rpms where 8200 to 8540 depending on what nozzle ring i was using. and my speeds where79/80+
have you checked your afr?
there are several things going on with your setup, for your rpms to be that low. you should be at least getting 8100 rpms. and you still have the oem pump and liner too?

Boost is low, as well, for that set-up. The problem is I don't know where to tell you to start looking. There are other guys here who have much more wrenching experience than myself. I can only tell you from my experience riding and monitoring my ski. Sorry I can't be more help.
I have my set-up close to yours and I see 8250 - 8550 rpms with 13lbs boost.
Unless you somehow got a prop that was supposed to be 13/24 but is actually closer to a x/26, but I still don't think you would be that low on rpm's and boost.
my .02 cents.
