Nice work steve45. Yes grumpy i did get those cams installed but to get any real gain from them i had to put a set of adjustable gears on them from kawi preformance. The cams definitely made a...

Not yet still a work in progress.

I was under the impression riva's stage one tune is a 93 octane tune but I'm not sure so I have emailed riva to confirm.

Yeah changing the pump would have made getting more top end a lot easier, but i would have had to modify the pump tunnel if i use a larger pump. I think on this conversion i just wanted to change...

Well been playing around with it for about a week now nothing new to update top speed, still trying to figure out the best pump setup. I definitely have a lot more power on the bottom end and mid...

Here are some more pictures im going to try and do a video soon of everything thats been done. Love the newer style gauge and all the real carbon fiber....

Conversion grades almost done! Lost 30lbs and gained 20 hp.

I used a 2008 250x rotor on a 2004 STX 15f. It fit without any modifications

Do you have the cams from the 260x still?

Checked the injectors they are not working, i know everything is good on this engine because it starts and runs fine on a different harness and ecu. so its either the harness or ecu, is there anyway...

I know i have fuel pressure i will check if they are firing. If they are not firing what would cause that issue?

I have a 2016 15f that has no spark on all wires. There are no codes on the dash. I have replaced coils, roll over sensor, voltage regulator, plugs, and plug wires. I have checked the fuse's all...

I didnt try to install the stx air box i never flip mine, you could probably get it to fit but you would need to customize the hose from the intake to the air box, where i mounted the ecu might be in...

Just fyi the 15f tank wont fit in the ultra 150 hull only the 12f tank fits, but i would recommend finding a ultra 130 tank. Thats what im switching mine to, the fuel pump fits perfect but you will...

Yes they are the same but the cams are different

I have been working some major upgrades for the first conversion i hope to have it completed soon and i will post a video update on that ski. Conversion 2 is a major under tanking i should have alot...

Crazy thing i just picked up a 2004 f15 yesterday in great condition for almost free. This is the same year I used for my conversion and it has identical hours as mine when I did the conversion. I...

Speed sensor

If you are referring to switch your 2004 for a 2015 and newer gauge it won't work unless you switch everything electrical. I'm in the middle of converting mine right now. My 2004 gauge will be for...
