I rebuilt a 61x to go in my FX-1. Here's the list: Hotrods crank coated pistons FP B-pipe limited Protec rec head ?? MSD enhancer Compression after 3 tanks of fuel = almost 200psi Been running 92 pump gas. I am a little freaked out about the psi. I dont want to hassle with using avgas on...

Well put.

What would be best for his application, a small hub 12/17 swirl or that big hub 9/17 swirl? Oz

If you do pull it, take a few digital pics so you remember where stuff goes and routed.

Just like Kahuna said, It simulates the lengthening or shortening of the chamber depending on where and how much water is injected. Gives you the option of tuning for top, mid or low end power. Read Factory pipe's site.

As far as the setup wake, watch a little freestyle video and get some ideas. The extended plate will affect your abililty to get air. Just my .02. I am still somewhat a rookie to freestyle.

Finally posting the semi-finished innards.

Doh!

Cool Crab, thanks. Ill just have to match them up to my different hulls to see what they fit the best.

Hey Craiger, the lake was a whole degree less nut chillin tonight!!! WOOHOOO!!! Starting to lean out the FX a little, its really starting to come alive now. Slippery little bastard it is.

BIG difference between the 650 and even the 61x in power. IMO.

About time he comes to his senses. Hey nothing wrong with that old school vintage crap, but its time to get the heck with it and fork out for an SJ. Thats where the real fun is. My girlfriends son just got the SN SJ I found for him down there. Has a Protec pipe and head, plate, scoopy and AL...

I have a FX-1 stocker as well, and have basically zero vibes. Something is outta whack on the mod.

Thanks, thats a great explanation. Only thing is.....Now I gotta take that freakin B-pipe off again....AAAARRRRRGHGGGGHHHH. I am also not putting the shim that goes on the lower bolt of the midshaft housing. The pump already needs to be shimmed down in the back. Question: If you dont use...

I am having the same issues with my FX-1. Seems to vibrate up to about half throttle, then smooths out. What about pump alignment? And why check couplers with rubber out?

Took her out for the first run last night. The damn thing goes like a scalded dog. I got two issues that need dealing with. Its alot louder than I wanted or anticipated. Makes me wonder if the waterbox has been gutted. I am using single line cooling with a restricted pisser coming off one side...

Craig and Tanner, have fun, take lots of pics. Tanner, best of luck at the races kid. Man I wish I was there.

Thats a damn fine looking ski I say. Ride the thing silly.

Yeah, just got my first one. Hard to tell about the cranking performance since I put it in my new build ski w/180+ psi. But it started it fine.

Long been done, she's a runner.
