Hi. Obviously I do not think my argument is ridiculous just because it is different from yours. :-) I also like learning about other viewpoints.
OK, so it will be interesting to see if you can walk your talk.
Didn´t say your arguments are ridiculous, the fews you have, but the WAY you argument is so, if somebody says something about Naish products in a negative way. That´s a difference but ok, I understand you are protecting your company. "Brand affiliation: none" - should be changed.... :)

Anytime there is an argument over the single inflation we all fall into 3 camps. One camp who likes the octopus system, one camp who likes the external single inflation system and one camp that prefers multipump systems. Personally I prefer the octopus system because it is simple, it works and to me it is easy to work with. It would not be highest up on my list for kite purchasing decision, but kind of on the secondary list of features I want.
OK, got your point but you were talking about only two groups before and forgot about the priority ones of external single inflation.(see my answer about your way of argueing above) Nobody mentioned mutlipump before except you.(if so, please help me find the passage in one of the posts). Of course there is still a small group of fans of this system, too. But I think we can neglect them if disussing the pros ond cons of Octopus Sys. :wink:

I was arguing to the people say they just want a multi pump system with individual bladders that Naish had a kite like that and they removed it.

Secondly I have seen a ton of kites with external multi-pump kites have problems. There are a few things that happened that will not happen on an internal system. The first is accidental disconnection. The rubber hose would just come off...if the kite crashed the probability of that increased. It canpt happen on an internal system because the the pressure in the bladder keeps the system connected.
OK, theoretically right. But when did you see this happen in the recent years? Not 10 years old kite models please. I asked you before what fabricat you saw hoses rotting and popping off. Still waiting for your answer...

The second was that the hoses themselves would become brittle over time when exposed to sunlight. Another issue was that people would not clamp the hoses so the kite would deflate if there is a leak.
I can chime in, a hose was disconnected on a Core kite when I was renting one in Mui Ne. Not an old used kite at all...almost brand new.

Hoses were leaking on my own Airush Lithium after approximately two years. Lived in Thailand at that time but always stored my kites inside my house and didn't kite that often.

just would like to add an INTELIGENT non-partisan question here about a leak at the MAIN inflation valve of my naish boxer 2017...

have just done the famous bubble test and the oNLY place i have a leak is the actual inflate/deflate valve....it is NOT at the seam where they thread together..got that nice and tight....its actually leaking right out the big hole...the little rubber disc/flap that allows air in but not OUT....is somehow allowing air OUT.

It LOOKS perfect, no cracks, no sand, seems to SEAT well...but obviously its NOT...the leak is SLOW...but within 10 minutes the kite goes from rock hard to 7psi and then another ten minutes down to 6psi...

since its the ONE strut boxer...the rigidity is pretty important...it flies like a DOG when its a bit soft.

ANY one else have a MacGyver solution for this? short of trying to ask NAISH for a new rubber flapper (which they probably dont even stock) or hiktting up other Naish kiters maybe for an ORGAN TRANSPLANT from their old kites that havent been thrown in the trash yet...not really sure what else to do...im THINKING of maybe trying to glue a perfect sized plastic disc to the underside of the rubber "flapper" but that might make the SEAL even worse....

grateful for any ideas.
buen vientos!!

think i got it figured out now....just ripped it all apart, lubed up the rubber parts, fine sanded the plastic parts..and seems to be holding air now.

Hey Chirojoseph,
My last kite session I had the same problem with my Naish 12M Pivot. I did the bubble test this morning and found the same thing you did, a very slow leak at the main inflation valve. Could you kindly expand on how you resolved the issue? I am hesitant "rip apart" anything. Your experience and a more detailed instruction will be a big help to me as well as others.
Thanks!

So there is a slow leak when the top screw lid is closed? Or when it is open?
Did you try to just blow little on it in case there is sand stuck down there?

Top
The leak was from between the valve seat and the main screw (not the top screw-lid which was closed). Admittedly I did not attempt to blow away any possible sand. It looked really clean, but I will have to give that a try. I was considering removing the o-ring (if that is possible) and checking /cleaning it. I was also considering putting silicon grease on the o-ring, but was concerned about it attracting more sand.

Yeah on any kites that run Boston valves you have to be pretty cautious with sand getting in that O ring. Pumping my 14m Pivot a couple weeks ago I could feel the kite way softer when I was ready to launch. I went back and checked the valve and the O ring was actually unseated and a some sand was in the channel. Cleaned / reseated the O ring and it's back to normal.

I've had that same issue with Cabs, Switch and others. Part of the pre-flight inspection now.

Also, be careful when you pack the kite. I had my Pivot packed pretty tight when I traveled and also had a slow leak when started to use it. It turned out that the threaded cap had deformed the lower part on the v-shaped area that seals against the rubber gasket.
Luckily plastic is viscoelastic so after a while it regained its original shape.

I didn't know that could happen. I always screw the top very loosely when I roll up the kite. I remember my old evo would leak like hell if I left (tried to) the struts inflated over night, but these are made of a much harder plastic.
