Cast can deal with the heat better

How so?

Yamaslut - notice the "secret " there have been some talking about their pumpsetup and intake ducts, people asking for pictures. So i posted them here, not everyone has fb.
Haha Tom21 i feel you

Maxx wasn't hiding the pump ducts or intake.. they were hiding the actual pumps.

[special fx]

Go....go....Godzilla!

Did you see how tiny that purple ski is???? Either that or the girl is a giant, and I think not!

 

[Idok]

[egbrig]

That pipe looks like a R&D pipe copy. A very good pipe if you know how to tune it.

 

[Big Kahuna]

Yup. Copy of the R&D.

It really sucks that whenever you touch the throttle it backflips or 360's.

With those wide intakes is there more potential to cavitate when leaning it over?

There is a cast big bore PV coming to market in the US very soon and once it does you will see how many guys start going that way.

Excited to see it in action! Got a look at the piston size the other day, it's a beast!

Looks like the power valve setup is a bolt on part for that cylinder or is it just my bad eyes?

 

[Twinturbostang]

Ya the jap one looks like 2 part jugs and then a head. Crazy.

 

[Tyler Zane]

im calling out the crazy, bridged, bat wing exhaust port. thats just ridiculous. i once read in a old book that people may try crazy exhaust ports but its really much more simple that that. the true limitation for a 2 stroke is expansion chamber development.

its pretty safe to say those are purpose built skis, not meant to get off plane just tricks, the height there gettings insane but most of us like to actually ride skis not just do tricks that thing would die in the surf i know someone that rode one posted on here said it was very hard

those are just skat knock offs. and there is no sercret anything being released in this thread. like dk said its something with the pump.

 

[joesuperjet]

Looks like that cylinder with bridged exhaust is a cast one ... are they making those big one 94/95mm pistons in cast ?
Kind of strange that in today's billet precision world someone will do a cast cylinder again...

What is the OD of their sleeve for a piston in 94/95... not far from 98/100 I guess ...
will be interested to see the case, to see what's left of them especially if a stock one is used.

Nice to see some new stuff going on...

I'll take a cast cylinder over billet any day of the week!
