OEM reeds for stock ski

I am overhauling the carbs on my 1999 low hour stock ski (mostly ridden by guests) and wondering about the metal reed petals while I have it almost that far apart.

Should I leave them alone?
Replace them with another set of OEM metal SS reeds per Group K recommendation?
Replace them with the 64x fiber reeds?

Would be helpful if someone has the Yamaha part number for the OEM fiber reeds. If the fiber reeds perform the same I would like to use those as they are safer and will not damage the engine if they fail.

This is what SS reeds do to an engine if they break, I discovered it this last summer. Not pictured is the cylinder which will require a 1mm overbore now and the crank which is shot. They work great till they dont.

I think the part number for the 760 reeds is 64X-W0004-01-00

You can also get carbontech reeds and I hear they are more durable. https://www.carbontech.com/water/yamaha.html

Fibre Reeds stand a better chance of passing through if they break. The metal ones actually work really well. But if they break............... I have been running the same pair of carbontech's since 2003/2004.

Thanks Req, that is what I am afraid of and why I want to replace them.

Is there any reason to go with Carbontech over the 760 fiber? I like OEM parts.

Carbontech part number I would use is 202LT?

I remember reading years ago that they had a carbontech reed they used on rental skis that was stiffer and more durable. I have no idea where I read it or the performance implications. Any input Kahuna?

no idea. I just know I have 16 years on the same set. that tells me everything I need to know.

is that for full set or just one side? Got to be careful with Yamaha OEM Parts, some stuff you have to buy each side seperately, not as a pair.

Oh good question. 2 petals, so only 1 set. Dual carb, dual reeds, I need two... so it's the same price as carbontech.

Are you using carbontech 202LT for the dual carb SJ?

Do the carbontech include new patched screws or did you just use liquid threadlocker for reassembly?

I see nobody mentioned Boyesen fiber reeds so I will not consider those.

looks like they do come as a set for both. not a bad price. from what I remember, Carbon Reeds are stiffer, Fibre reeds are softer (If that best way to describe). Stiffer will close back quicker... Jr. or someone else can give a better description that I can.

see my post above. I traded some VForce1's for stock cages and reeds, have never removed them.

Well, you can forget the OEM 760 reeds as an option. I just got a call from my dealership telling me they couldn't finish my order because the 64X fiber reeds are now listed as discontinued so he can't order them.

I also saw they are discontinued but there are a few available on eBay. Based on the positive feedback above about the carbontech reeds I was going to go with those.

Also on the ebay ones, the Yamaha parts diagram says 1 set is needed but on ebay for the same price it only shows 2 reeds with 8 screws so this would only do one cage. I am still not sure if you trust the part number and diagram or the pictures.

I came to the same conclusion. The parts fiche for the SJ and 760 both show only 1 set required. But photos of the SS reeds clearly show two sets included, and the photos I found of the fiber reeds only show one set included.

I'll check the OEM SS ones when I get home to verify how many are in the box.
I have personally never seen the OEM stainless ones break and have see quite a few high hour 650 & 701's with the original stainless reeds. I think it all depends on hours and how much water they ingest. I will probably just run the SS ones I bought new for a few years then change to carbon tech's at some point.

If you have it apart, I would recoment replacing the SS pedals. Like someone stated above.
They are fine until they start to chip. Then get very expensive very fast, with resulting damage.
For most all rec use SJ motors I recomend Boysene power reeds. The glass version.
Easily last several seasons and withstand the harsh abose water injestion causes.
They sell for about $80 for a complete set. Money well spent in my eyes.
Carbon offer better initial performance, but loose tension quicker than glass.
Those sell for aprox $125 a complete set from several manufacturers.

BK, 16 years on a set of carbon pedals?. While they are still intact, im sure you have given up a considerable ammount of performance. The tension of glass or fiber over time diminishes. As a result, so does performance.
You certainly got your moneys worth out of them, its time to replace them!

Ski ya, Paul
