Chris' Surf Battle Boat... Never done!

[tightithrash]

#1 the ones he has on his ski are drilled out and lighter than an old umi kawi style coupler..is it going to make a huge difference??..no but it will make somewhat of a differnece

#2 if you ride in the surf hard you will break the stock ones..they are cast junk

#3 the advantage of the billit front cover is that it uses an oring so if you need to remove it you do not have to purchase 20$ gasket each time

hope that cleared it up for you

:lightning: :headbang::burnout:

Im not exactly sure how you measured your couplers, but I just weighed and compared both sets of couplers a few days ago.


The yamaha OEM cast couplers AND dampener was 1 lbs 10 oz


The BILLET kawi conversion couplers AND dampener was 1 lbs 7 oz.


hardly half a pound. Perhaps yours are milled far lighter, but as for me, I think the widespread claim of everyone feeling a large snappy difference is a bit bogus. The yamaha coupler is roughly 3/4" larger in diameter, and though yes, there will be less centrifugal inertia, it wont be that much as compared to an aluminum flywheel when you are talking about loosing 3lbs on a 7" disk, not 3-4 oz. on a 3" disk. Personally, unless your grenading the yamaha couplers I think its a bit of a waste of $100+ . (i also dont understand the recent hype with the billet timing covers either... but thats another story)




On the bright side it does look hot as . =] Good build!

When I installed my couplers, they were the only thing I changed on my boat, and I absolutely felt the difference. And, I didn't spend $100+.

The flywheel cover utilizes a o-ring as wydopen has stated. No gaskets are wasted when the cover needs to be removed.

It has been a very very very long time since I have given my boat any love; mainly because nothing has broke, which is good, but mostly because I've been busy this last year starting a business and I purchased my first home.

I repaired some of the gel coat flaws in the WDK hood. There were some air bubbles under the gel coat that have caved in. Filled those in, smoothed them over and shot some rattle can black paint over the whole hood. It doesn't look the best, but its cool for now.

I rode a ski last weekend with riser bars and loved them. I don't have the money right to do a full riser bar conversion, so for the time being I built a hood pad to elevate the pole. I haven't glued down the pad yet, I'll probably move it a little further to the rear of the ski...

I plan on finally installing a bilge, primer, and properly securing my limiting rope to the dash rather than under the hood latch before my next ride also.

So not the best pictures in the world, but I just got done installing a Cold Fusion Riser Bar turn plate and Blowsion riser bars.

Had to grind the crap out of my chin pad to get the bars to clear.

Also the large center hole on an x-metal pole is not large enough for a stock bushing. Had to take some stock bushings down to Cold-Fusion and have Carl take some of the material off with a lathe in order to get them to fit on the X-metal pole.

I'm running a pre-production/protype turn plate so the ones you buy from carl look a little different.
