Hi Everyone,
It's a New Year....time for new resolutions, new beginnings, and NEW MODS!!!!!!!!
With my desire to run and finish LB2CAT and some other offSHOre endurance races this year, I decided to go BIG on my SHO.
That being said, this thread will SHOw what it takes to install a Riva Stage 3 kit on a Yamaha FX-SHO....which includes fuel, cooling, pump, and electronics upgrades needed to feed, cool, and protect this beast when she's done and rippin!!!.
I say Stage 3+ because not only am I installing the Riva Stage 3 kit, I'm also beefing up the shortblock with aftermarket rods, pistons, and head stud kits. Why you ask?
The Yamaha platform is proving itself to be a very stout platform, even when running the Stage 3 kit and cast internals. Even though some individuals are knocking the cast internals, many people have been pushing the envelope and making 330+ hp at over 8600 RPM. Jerry and JD1 are 2 examples. Deans Team Racing has raced a whole CC season with his FZR's running the Stage 3 kit, sometimes reaching as high as 9000rpm during a pump unhook,,,with no issues!!
But offSHOre racing is a different animal. And the usually constant, volatile sea-states are extremely punishing on the skis, riders, and engines. Also, when watching the race results of the MH 300, LB2CAT, and other endurance races, I started to get worried by the high attrition rate/DNF's witnessed in the high-hp skis in the open-class races. Considering the sloppy, washing-machine waves that we have to run off the East Coast, it's easy to visualize the beating these engines can take from hooking/unhooking in the chop for long, extended runs.
These are the factors that I considered as I made my decision to beef-up the shortblock on my SHO, particularly the connecting rods and pistons. I plan on installing all ARP hardware and the RIVA valve train upgrade kit as well for added reliability/longevity. Not to mention an eye-to-the-future when bigger boost wheels come out....
I will also be making modification to the pump and prop to a more suitable offSHOre set-up, as well as the handle-bars and other assorted offSHOre tweaks.
Stay tuned....
I would definitely like to keep this build thread positive and on-topic. I welcome suggestions and ideas that you guys have for the build, but please keep brand-loyalty arguments and other assorted BS out of the thread.
