Title: I feel the need, the need for new reeds
Post by: cyclegod on November 19, 2015, 08:06:28 pm: I'm having trouble finding Boyesen reeds for my Suzuki GT250X7, I have one set out and they measure 44mm long x 35mm wide with mount holes 18mm centre to centre. I know Suzuki like to common up their parts sometimes but I can't even find a bloody part number for them to cross reference, I "think" they may be the same size as the early RM80's but until someone measures theirs and tells me I'm stumped.

I have a considerable stock.
I started to look for you when you through up this thread
http://forum.ozvmx.com/index.php?topic=39097.msg376417#msg376417 (http://forum.ozvmx.com/index.php?topic=39097.msg376417#msg376417)

But got distracted, crashed out and forgot until now.

I will have a look if you put standard ones with dimensions up :)

Reed gasket 13156-11300

They don't come up as fitting any other models and the reed itself is not listed separately

Are you certain that 18mm mounting is center to center?

Post by: John Orchard on November 19, 2015, 10:15:53 pm: This is the link to the GPS Imports website for reeds & reed material, they list .40mm which would still work ok.

They used a pic of me on my GSXR1000 racebike at the top of the page; I haven't ridden for them for about 4 years, go figure!

Post by: Lozza on November 20, 2015, 05:25:27 pm: Unfortunately the Aussie Polini sheet is hideously expensive, I got some from a scooter shop for about $30. The Suzuki power reed doesn't really like carbon petal material though(they break in no time), besides the stainless , the twin petal boyensen seem to be the only option for replacement/improvement

What do you think the reason is that the Suz power reed doesn't like carbon? It doesn't open any further, or more often than I normal reed valve assembly I would have thought; interesting.

I wish I knew why John the only thing I come up with was the dimensions of the petal itself. Tried all manner of combinations on a RM400 and a 125. The 400 petals lasted maybe 10min, 125 just ran flat.

Post by: cyclegod on November 20, 2015, 09:30:04 pm: I still need someone with an RM80 to measure the reed dimensions as I don't fancy wasting money on buying a set just do check it.

Do not buy the RM80. They are incorrect.
I have emailed my oversea supplier. He will answer and he will know. Tis the weekend though.

Post by: Mick D on November 21, 2015, 10:57:11 am: OK, got an answer :)

It appears that the earlier RM80 will fit :) just not the latter model ones that I measured for you.

Boyeson Dual Reeds #610

There are heaps on US ebay if your local dealer hasn't stock.
