What do you think about Boyesen 2 stage reeds, I check the search and i saw that it is good but I heard that the second reed is too fat and never open in 250 2 cylinder bikes and it is only for one cylinder dirt bikes!
If the second doesnt open the nsr will have good midrange because the small reed is thin and opens fast but at 10.000 rpm the nsr loose power and the stock are better!
What do you think?

Personaly i'd stick with the Tyga Hi Flow Reeds. If your after that little more on the top end and mid range go with the carbon fiber petals.

Your 100% correct. VForce beats all.

I order tyga! I dont want to use carbon for safety! My nsr is for road use so i dont care about 0.5 hp that tyga says it gain with carbon

Why aren't carbon reeds safe?

If they snap then they simply get chewed up by the engine and spat out in a puff of dust...

Carbons quite tough material, I had a reed break up on a KTM and it lunched the big end! Having said that I would be suprised if plastic or glass fibre reeds didnt do the same thing.

Take the time and do a comparison dyno run when you get the new reeds . It will be good to see what you get .

Four stroke?

How dare you! It was a two stroke Dave

Heh heh!

Tyga offers reeds? only found CF petals on their site.

I got MC18 if it makes any difference

Yeah for a 21/28, I can't see why they wouldn't fit in an 18.

I think they arent !!!! And can do problem in engine.

Are you sure they are safe???

I've got carbon reeds in my NSR, which has done a couple of seasons racing, a bunch of trackdays and a few thousand road miles. No problems so far.

I've also not heard of someone destroying their engine due to reed failure (until the KTM mentioned above!).

All these things are down to an individual to assess the risk and what they're comfortable with.
