    Where are the Riva numbers coming from?

    I just rode two of my friends RXPs with Riva stage 2 and one ran 7850 with the Solas 15/20 70.5 MPH radar and the other has same thing but pitched stock prop and is 8100 @ 72.1 MPH radar. I figure that is respectable considering the cost he has in it compared to mine. I ran 8450 and 76.4 MPH radar with same stock pitched prop. Tried the 15/20 on my RXP and only pulled 8100 and 73.4 MPH. Corrected altitude is 3100 ft with BP of 29.4, Im thinking most of the good numbers must be coming at sea level with BPs of 30 or more.

    I ride on the bay exactly 2 miles from the Atlantic and I run 75 all day @ 8000-8050rpm. My only changes are a Greco water strainer for the IC, a PPG thermostat, stainless wear ring, new clutch, and a shaved lip on the bucket. Otherwise all Riva. (0 elevation, 85 degrees avg., and usually 90-100% humidity.)

    Note: Got back 200 rpm on the clutch and wear ring combo.

    There you go Air pressure, are you in salt water? I dont know about there clutch they dont have boost gauges which sould be a first in hop up. Your most likley riding in 100FT- 1500 ft corrected air. I'm liking my SS wear ring alot! Bruce at Extreme sports is one fine indivdule! Had a little trouble with mine and he took care of me BIG TIME.

    I do ride in salt water, although not as salty as the ocean. On less humid days, I've been turning 8100 and running 76+. No bad w/out any big internal changes. (Can't wait for the fall for the cold water.)
    My stock clutch was running 5nm of resistance and the new one is at 12nm. I replaced the clutch at 40 hrs. I have 70 now and am extremely happy. Bruce helped me with the ring as well.

    Burnwater,
    I assume you have the rr ecu? If so, that confirms my findings that the rr ecu does not like that 15/20.
