Freestyle 9/15 to much for a 650?

[Fstrkls1]

I'm looking to buy a prop. Every one says run a 9/15 but is it to much for a 650? My current mods are: modded cdi, cheater pipe, flame arrestor, bored pump nozzel, and I'm waiting on a lightened fly wheel ( it's in the mail) with what I have done will a 9/15 be to much? Or should I go with a 10/16, 11/17?

higher the number the higher the load on the motor.

9/15 is gonna be the easiest to turn of those three, but if it's a hooker 9/15 then it's a BIG hub, setback, swirl which create higher pump pressure and have much greater grip so they will load ur eng quit abit more.
We jus put one in my buddy's 650 that runs like a good 701, and we ended up running a 1.5mm spacer behind it to free up the revs a bit..

I have a hooker 10/16 in my SN
which now has a 650, 185 psi, protec, ported, MSD, etc
and it runs great!

do not put a hooker on a 650 imo use the $$ to get a 701 and mod that thu time

There is not many modern impellers that are low enough for 650-701 engines. The hooker 9-15 is as close as I have found.
