Not sure what your planning on for motor buy my sfs circus with a ported 760, msd enhancer, pfp run wet, oem 155 with jetmaniac prop was a riot.

Found. Thanks guys!

Pressure test your PFP chamber. If it's broke that would explain the lag/lack of rev feeling you're experiencing. Ski will sound great out of the water but as soon as it hits water you can feel a very inconsistent ski. Like others said, you should be pulling at least a 9/15 - 10/16 with...

140 Main 142.5 Pilot 2.0 N/S 95g #60 Return 2 Check Valves Jetting is from my old XS900R race gas setup Your compression numbers do seem high for an xs motor

the heel blocks themselves are premade. They take a little sanding to get them to fit perfect but yes they fit in XS foothoolds on dvx/helium for pricing message tricky

order the premade kits from @tricky1 when set up correctly there is nothing better....especially on xs hulls

@JKMike im running into the same issue on my new xfs. I am going to cut out that oem battery mount thats epoxied into the hull to drop the waterbox down. A buddy of mine cut and rewelded the waterbox, but I think im going to pass on that route.

@Storbeck From what I can tell/have heard the LS1 the booster is not "centered" in the carb. Its offset so the fuel doesnt dump directly on the throttle shaft and disturb the flow or when the carb is at full throttle it doesnt dump on the plate, it dumps directly down the throat of the carb

why are 2 girdle studs missing out of the cylinder? exhaust side middle and rear

yes

Have a nice raptor trim in the parts for sale section

here’s a pic of the xs in a q8 build we did for reference. If I recall the Ariel does have a little more room to work with.

@jharvey1984 Heres a better option and it has comparison pics in the thread to the oem for size comparison. If you go this route you might not have to change chambers. From what I remember the xs does fit but it is tight https://www.x-h2o.com/threads/jetmaniac-sj-standup-ski-waterbox.181445/...

Xscream waterbox works

I will say back when I was using these they were just released (maybe changes have been made since). Justin Sylvain and I found tuning them for pump gas 900rr setup to be very sensitive to air temperature. If you are already in touch with Phil you are in good hands and he will definitely have...

I ran them on my XS900RR a few years ago. They were difficult to get dialed in and I found they were very sensitive to temp changes. From my experience I found I had to set the screws to a specific setting and adjust the jets accordingly. When they are right they do perform very well. If I...
