So looks like the new clutch is now available but what do the specific notes mean?

I run a Stage3 on a 2017 GP1800, same hull and SVHO engine platform so I would expect the same results on the 2021.

I run the ET17 wheel and custom tune from Jesus.
Acceleration is a huge...

Also keep in mind that you can have custom tunes with MaptunerX by adding the data logging option. You can get custom tunes from Jesus at Riva by email. For instance if you are at higher elevation...

I would put it on a switch or plan on pulling the power plug each time. If you leave it "live" to the battery it will drain the battery. I left it live over night first time using and battery was...

Yep, exactly what Adam said, had this happen on a 09 FZR a few weeks ago. Disconnect the bilge pump and replace fuse and all was fine. Obviously have to replace bilge pump.

RIP Mr Jordan, thank you for all the help over the years. You will be missed.

Jerry, I feel you are setting us up for something.

Well let's see if you can answer this?
Will reving it on the trailer be a issue in 2021?

I am using Maptuner and no fuel pressure regulator.

I am running the 17# wheel. Stock fuel pump but 1K injector's.
@9k rpm I have seen 19.4# of boost.

The stock wheel VS 17# wheel is a big...

I was able to get mine to work also with a metal plate grounded to engine.

Yes, fine tune with the ring placement on/off.

Use the wear ring as a template as you sand down the transom piece. Sand a bit and the place the...

I tapered my transom plate using a flapper wheel. I did notice a improvement.
Seal the transom and the intake grate also.

Clutch change is not bad, just take your time. What wheel you going up too?

I am running the solas 13/18@8600 + rpm and no issues at all. The acceleration with the 13/18 is nice. 8-)

On the 2019 plate did Jim cut any more material out of the center area or was it just all cut at the mounts for more angle?

I wish someone was testing the plates ASAP !!!!
