I installed my mag with oem 2008 prop in my XFS - I still get some cavitation to my surprise. I am using a not so aggressive worx grate, no silicone between grate and ride plate - should I change the garte (e.g torrent from ATP) or silicone the space in between? Did you have a similar...

Darn "turf" so slippery that even with good shoes I fly off the footholds... anybody else has the same experiance? How did you deal with it? The turf job is so nice on the XFS, but if it will continue to assessinate me I need to do something about it.. and quick... Be obliged for any...

Recently I had a chance to visit Chris and Lisa @ ATP and I can tell you that was one interesting visit. As some of you may know I am an ATP dealer for about 4 years now, but never had a chance to visit my Partners, and thought it is the right time, especially becuase ATP moved to new premises...

Just for fun...

Hi all, I currently use a cutback 08 prop on my small bore XFS (needed to prop up from 12/17 skat swirl due to the boat cavitating). I was thinking that maybe bending the prop for a bit more low end pop would be ok... so anybody bends their own.. any tips? Heat no heat? How to measure the...

Everybody is very much welcomed on www.4aces.fora.pl the only freestyle dedicated forum in Eastern Europe :) Thanks guys!

I have a small motor @ 727cc in my XFS. The power isn't bad for this ski, I was able to pull a 3/4 of a BF after 10 min of riding, which was NEVER possible with my RN - i like that. What I do not like is the way the power is transferred the water. After e.g a 180, it takes a bit of time for...

The same 727 cc motor and pump in my "light" SJ had no cavitation issues at all. Now, in the XFS Current prop is skat 12/17, (i have the oem big hub 2008 - 3mm to try) and it cavitates badly atimes. No its not damaged and pump has FS cone and bored nozzle to 85mm - what do you think? Its...

I got my motor compression tested after fitting 33cc domes and I got 15 BAR = about 215 PSI - not good for pump gas. I can source E85 fuel which has about 104 octanes which should keep the motor from deto. What do I need to change in fuel delivery / ignition to run this properly?? I know the...

Hi all, After a very very long waiting time (8 months roughly) my white fiber glass XFS arrived in Poland. It is being processed by Customs. By finding a cheap shipper (sea transport) I paid only 1.5K usd for shipping 2 of them (all taxes and so on included). Onto the build: The motor...

Hi all, I got from a customer, an ex-Ross Champion ski (orange and white, JSU graphics on front) with about 760cc. It is a bibore ported 61x cyl on 62t worked cases and bolt on goodies, It uses 65U pistons. It was brought to US to Poland some years ago, was somehow "adjusted" to work on...

Hi guys, I am considering building a cylinder to have an alternative to my 727cc. I am on a tight budget, thus not able to jump on the billet cyl. bandwagon (although I would mind it at all ). Not sure which way to go to get best power. Old saying says: no replacement for displacement...

Hi All, I have a snag with my ebox. Seems like its leaking. The gasket was new, not sure whether the cap can leak as well? Anybody any opinions on good fix? Should I tighten the ebox covers more?? This mositure is causing lack of spark sometimes with my EPIC... Thank you

I've been on the forum for about 3 years now and I can say this has been a wonderful time for me with all the knowledge and friends I acquired durng this time. I got hooked up on jet skiing badly and cant imagine a summer without riding. I started with a 550 had it for 3 seasons and learned...

I was thinking to upgrade my motor for next season, by making it a stroker. Preferably 5mm. I do not know where to get such parts and what lenght should they be. Can someoone help out with that? I want to use oem 61x ported cyl or go bigbore with a 62T - what you guys think? I need to run...

I am considering (strongly) to further enhance my freestyle capabilities. I spoke with a dealer (Q8, RRP, Bun, etc) about my current platform (RN SJ+ ported 727 with bolt ons) and this is what I got. Hopefully it will answer some of our questions, especially about BF with "stock" motors...

Those helicopters look sick... generally they know what are they doing.. these guys on here??

Intro: Ski: 727cc, ported (cleaned up windows, bored exhaust window 70% of cylinder diameter, EPIC ignition, 12.1 bar compression (pump gas 98-100 octane in Europe), Bpipe Ltd (bored, polished), jetworks valve, cone, cutback -3 mm 2008 oem prop, bored nozzle 84mm, oem carbs (rejetted, no...

A customer brought in a 2007 SJ with drowned motor. I started looking at the parts and noticed that: - these carbs (2x38mm mikuni) have no Low or High adjusters!! - the oem exhuast seems to have some sort of insert that looks a bit like it is supposed to affect emissions Anybody any...

Hi all, I am trying to dial in my old pp 550 kawi with practicaly all the goodies. It has a westcoast Works pipe, 44sbn, ported cylinder, hi comp head, 15 skattak, bored nozzle by 2mm, etc... The ski runs well up top but it takes time to get there... I think the problems are or could be...
