Boysen said on there web site that you don't need a reed stop and can use there rev plate . But I can't find a rev plate for sale on there web site . I have a Suzuki with case reeds and am wondering if I should modify my spare reed stop to just hold the reeds to the cage or not .

I tried some Boysen reeds back in the day on my RM. I followed the instructions to a "T". Raced the bike and went right back to the stock reeds. I could not feel any improvement in the mid-range and the top-end was slower, if anything, even the mid-range seemed flat as well. The reeds were a two stage style for my year and motor size. The instructions made no mention of needing a re-jet. Just my two cents. I would only use the Boysen reeds if you don't trust the stock steel reeds to have much life left in them.

The bike is a PE175 and has piston controlled ports so the reeds shouldn't kill my top end that bad .

You think broken reeds can't make it up the transfer ports?

As I remember you needed to increase the reed stops clearance so the thicker composite Boysen reeds would not restrict the flow. My take was the Boysen reeds softened the power increase. To me at that time, Boysen reeds were better suited for big motors. Never tried them on a PE 175. But as said they would be safer than using the stock steel reeds for the long term health of the motor. Not for any increase in power. As for not having a reed stop, that will allow the reeds to flex farther and increase the chance for the reeds to break. I'm not saying not to use them just understand there will not be any increase in power they only soften the power/RPM increase.
