    Talking R2 reflash with no retainers for my 15 fzr?

    Hi guys, i currently have riva scom with intake, exhaust, cooling kit and pitched prop with a contant speed of 75 mph on garmin gps. Ive been wanting to do a reflash since i got the ski but was scare of blowing up my motor. I ve seen some people running r2 reflashes with the same mods i have doing 79-81 mph and no retainers, now my question is: would i be safe by just adding an r2 reflash and depitching the prop for 8500 rpm with no retainers? I use the ski almost every weekend for severe saltwater use

    R2 reflash is safe. Can't rev 8500 though. You'll be all over limiter.

    Jerry from the GH store says even the r3 reflash is safe on the SVHO, since the stock valve train is proven reliable up to 8700 rpm.

    8550 limit for R2. Was turning 8500 and brought it down to 8400 with a Lucky13.
