I have an oem Gen2 X-2 hull lying in my garage, thinking of using it to create a better flatwater fixed-steer ski and I am looking for ideas. Will mould a lightweight version once I am happy with the ride. My thoughts so far: Larger Pump - do I stick with a kawi based pump or go with a 155 Yami...

Check out the short tray on the Super UFO and the Vertical reed system on the new crankcase: http://www.bun-freestyle.com/images/catalog/2013-14catalog.pdf $30160 for a complete ski, pricing competitive with USA built skis.

BUN is casting crankcases that have the intake aiming 30% more up and accomdate +14 strokers with no machining needed. http://www.bun-freestyle.com/parts-engine.html#waz-cylinder

I am looking to buy an AM engine for my Carbon Gen2 X-2. It has been shortened, 79" tip to tip, 71" bottom hull, intake increased to 160mm and running a 146mm SB Mag at the moment. RTR weight 305lbs with 8 litres of fuel in it I recently moved to a city that is at 5000ft asl which causes a 15%...

I found this today and have emailed to see if they can supply a kit for jetskis: http://www.ecotrons.com/2_Stroke_Small_Engine_EFI_kit.html

As the title says I wonder if there is an optimum Intake gullet to pump size, as I see 155mm pumps getting fitted to skis with smaller and smaller engines. Is it only for easier drawing in of the water by the pump, does water 'storage' play a role? The Wabuzun and UltimaX hulls seem to have...

What size ADA domes should I use for 95oct on a SXR 800 @ 5000ft? It is a flatwater engine.

Does pop-off need to go up or down when going up in elevation? I know jetting will have to be reduced I have moved from sea-level to 5000ft. I have not run the engine since moving.

Some pics after shortening and respray. Going with a drypipe I haven't seen anyone use, recognise it from the graph?????????????:chairshot:

Found this in the Bikeman Performance Catalog for snowmobiles. Looks like an 800etec bored to 900 with a turbo

I have a customer with almost a completely stock WB1. How big can the nozzle be bored without suffering cavitation? I used to doing this with am props and modded engines, a bit wary with the lower hp and poor impeller design.

These designs reduce straight from behind impeller, stator vanes would be in beginning of our exit nozzles. http://www.youtube.com/watch?feature=player_embedded&v=OtgCEbWMtqQ http://www.wartsila.com/en/propulsors/wartsila-waterjets/waterjets#expandable_id Gets interesting from halfway through...

Has anyone got some kind of template / sizing of PFP? I have shortened my 2006-shape X-2 and would like to know if I have the space to fit a PFP in it.

Saw this on the Japanese DASA site:

Looking for a new starter and bendix to fit sxr800 type engine. WSM, Caltric, etc any good?

Where is the best place to purchase a MSD brain? Needs to be shipped to me in South Africa
