gday im sure this has been asked before but i couldnt find it anywhere.

i recently bought a best kahoona 09 9.5m as my light wind wave kite. love it!

i only have two issues wth it. I have to pump up the struts separatly before i pump up the leading edge. has anyone joined the struts to the leading edge with tubing to make it a one pump system? just to give me a few more minutes on the waves


also the kahoona has way too much bar pressure compared to my bws noise 6m. there is only one setting on the kite and bridle so i cant change bar pressure. is it possible if use the bws bar and lines on my kahoona? both 4 line setups...

I may be wrong but I don't believe that the bar design has any bearing whatsoever on the bar pressure.
Kites with light bar pressure bear most of the pull on the front lines (connected to the harness).
Let us know

Hi surfy31,

Changing bars will do nothing to fix the bar pressure. The bar pressure comes from the bridle setup and kite design.

You can change the kite to a one pump, but it will cost you more than the kite is worth. You'll need $150 worth of strut valves fitted, and then get a kite maker to open up the leading edge in three places, cut a hole for the valves, reinforce and sew the reinforcing pieces into the leading edge and then sew the three open sections of leading edge back up. Then add transfer tubes, clip locks, and cable ties and the whole job should cost around $500 in total. On an old 09 Kahoona, that's about all the kite is worth.

The Kahoona is cheap because you aren't paying for the little extra's you get on more expensive kites. It will be much cheaper to buy the kites with the extras in the first place.

DM

Adding all the valves on leading edge bladder means you now have twice as many possible leak points. You only need one of these to leak badly and there goes your days kiting.

I was looking at converting my kite by removing all the leading edge valves and making it a two pump system. Much prefer to get to beach and take 5 minutes longer to pump than get to the beach pump it up ; find a large leak and go home again.

Simpler is best.

PS 14 out of 16 valves on my kite have leaked.

Actually I don't think Darren is entirely correct on this one. It is possible to cheaply convert a multi-pump system to one pump.

Eclipse kite successfully did this using some tubing, a few cheap joiners and some cable ties. Works fine

How did they attach them to the LE bladder?

I still say no
