For the people running the three stage boyesen set up .Have you seen the top reed or is it the middle reed that looses its tension sooner.what I mean is which petal is visibly more open after say 20 hrs of good use?

Between me and two of my friends we have a total of 5 of the Boyesen Full Spec setups. One of the manifolds is from a SJ limited that has over several seasons on it maybe 100 hrs and just now needs new reeds. Our time with the Boyesen Full Spec manifolds has been nothing but perfect, but there can always be one that doesn't play well with others.

I was more interested in the life of the reeds than on the life of the manifolds. IF those reeds last 100 hrs and on the bigger carbs thats alot of time.
Thanks for the info.

The Boyesen set up on my limited (the one egbrig was talking about) was used and put away wet for three years. when I finally took them off to put ona mod blaster, the reeds still looked perfect. This is with 46mm carbs. That same system on my 6mm stroker went the entire year without a problem. That is four seasons on one set of reeds. I have noticed the edges on the bottom reeds are starting to fray, but after four years, I guess I can't complain.

dragin up a old thread here, I havnet found the same to be true as scottie,I bought his manifold and then bought brand new reed valves for it and the bottom set on the most outside edge are gapping out a ton,not even close to sealing,dont know if they are making the reed diff now or what but its crap.maybe you guys were using the older models back in 05,the new ones have a carbon pedal in the middle that holds up fine,but the outside fglass one is junk in my book

Your saying the bottom set of reeds are staying up. I assume you mean the reed that rests on the cage are staying up. Is it worse on the lower side of the cage than the reeds on the top side of the cage. How many hours?

the last reed that is on the outside with no reeds supporting it from behind are the ones that are stretched out and staying open bout 16th of a inch. this is only happening on the reeds on the bottom side of the cages. I seriously hope they have something better than these to replace them with,it would make more sense to me to use carbon on the 2 outside edge reeds,rather than just the middle one.
these have hardly any time on them,maybe 20 gallons of fuel,thats about 4 rides at 2 hours each max.

does anyone have any info on the diff with vforce 2s and 3s,I have some vf2s that I can grind the edges down of the plastic and get them to fit in the boyesen manifold

just came up with a diff fix,I took the reeds off a set of Vforce cages and used them to replace just the outside boyesen reeds,this may work out pretty well,The vforce reeds are much nicer feeling and have lasted much longer on other skis,but the cages are no where near as nice and dont look to flow as good as the boyesen cages,so maybe using the best of both will result in a better over all throttle response.
