lol.....4 skis & a boat and with that RXT you're building for me it has become my primary focus. I spent a good deal of time mofiying what I did last summer to the RXT and the GSXL was only given shy of 10hrs ride time after it's restoration was complete because nobody in my family I'll trust doing a good breakin...a sittin ski no good for me . Once warmer temps arrive I might give another shot at tuning the beast if no takers. It's either in the base timing or the prop. I had the base timing spot on, or at least I thought so, but my eyes aren't so good and timing it gave me a halo image and I focused on the steadier of the two images I got. Once I added in the Microtouch rev limiter I lost 2degress retard, which I found odd but jumpers let you correct it. Only wish I bought my 1st 4-tech sooner as I would never have embarked on that project and sunk the dough into the RXT instead.

Nice ski. I read your description. What RPM do you have water injection set to turn off? I did a few 951's with Coffmans and water injection and we needed to set it to turn off much sooner than what was recommended. It worked on a few of them.

sorry Joe missed your response. I still have it and chose to take another whack at tuning the beast and then decide if I want to relist it or not, killer is 4 skis and a boat and wife says i'm overtaking the property with my toys. I have rpms now up to 7200 and a few more tweaks/tests to go as follows
1.) Ski has a Solas Scoop grate that I'm sure is dragging it down on rpms so swapping for a stocker and retest...scoop is huge on the thing.
2.) Going to test timing retard @5k up and see if removing some timing up top increases rpms.
3.) Skat nozzle ring size variation test...currently runing 84/87
4.) Prop tweak
but come hell or high water this Coffman pipe setup will be turning 7400+ before I'm done! The thing pulls like a train and did have a few issue to button up with water injection limiting rpms
And to CrazyA...head pipe injection fully turns off at 6100 but jumper is set/verified to 5800. I'm assuming the fact that a real world test with the line hanging over the hull was residual water still in the line after solenoid closes. A good tip was passed to me from Bill O that it's best to install the solenoid as close to the injection fitting as possible to limit residual water, apparently even a 6" line still has some flow so I might try dropping the jumper to 5600 and see if pipe temps come up and help raise rpms a bit more because from the feel of the pipe after a good wot run I have more room.
