Head. Keep your reeds stock for now.

Or at least put some glass boysen reeds in there they won’t waist a piston if they break.

Get some late model OEM reeds. They're glass. :biggthumpup:

thanks for the replys.
so, if buy the 07 reeds they will be in glass. that's perfect.
for the head, should i buy blowsion or ada, and will i need anything else to make it fit.
will 170psi be enough

when i did this i went with the head next
i raised compression to 185 (35cc domes)
over all its a pretty nice and reliable setup

im considering goin with reeds next

but all i have now is
b pipe (limited)
prop
head
reed stuffers
and airfilters

id go with the head

ADA seems to be the preferred choice, but either head will come with what you need.

Before you order new reeds: If you're going to shell out money for new OEM reeds, spend that money on aftermarket CarbonTech reeds instead.
I suggested OEM because they are cheap USED.

go ada
185 compression
is premium pump gas
93 or 92 is the lowest you can run

how late of a model? I was wondering this myself, b/c one person told me "all yamaha twin reeds are metal", but I had thought I have seen a set of glass reeds come out of an engine that had never been dismantled.

 

[Matt_E]

I don't know.

 

[oxnard111]

I don't know.

What good you are... geesh.... J/K :biggrin:

 

[Mark44]

I have a RIVA head. It came with the engine I purchased. Some say they don't like the RIVA style studs, while others do. The RIVA head weighs more, but it works, so if it ain't broke, don't fix it.... right?

my 04 came with stainless reeds

Do you have a different ignition cdi or modified your rev limiter? If not, then the stock rev limiter is probably holding you back from full power.

Perhaps it's not by model year. GroupK mentions that some come with Glass reeds, and others do not.

I have seen both.

Don't mean to thread-jack, but can someone please explain the added benefit of going to an aftermarket reed?

Call me dumb, but I have flip-flopped back and forth from the cheaper Boyseen reeds to stock (because of breakage) and did notice a slight difference in the way my motor responded, but I was thinking it was something a little tuning would have taken care of.
