Just wondering if this looks correct?
 

It does from my sofa in the UK MotoDave0. Looks the same as a TY 175,which fits straight in my CT3.
I'd even like to bet it fits that AT3 you have too.
Take it it's out of a twin shock DT ?

Could be the camera angle but are the reed stops bent unequally?  Some of the manuals have a spec for the reed stop gap at the tip

That is what my question was about was the reed stops.
They look to close, the reeds will not open hardly at all
I am going to install a set of Power Reeds do I need to keep the Reed stops?
 

Looks closed up on the stops & uneven. Bend them out equally. I bend them until they scrape the housing on the way in thinking more is better which isn't necessarily true. Check the screws after tweaking the stops.

Okay RT325. That sounds good. I am putting a 175 jug that has been worked on.
On a DT125 bottom end. try and make a racer out of it.
Thanks again.
 

Hey, now i'm sitting up & taking notice haha.

Boyesen dual reeds will kill top end in my experience.  Can give a neat mid-range kick but suck for HP.  Yes, you do remove stops with Boyesen.

Manuals have the answers...  but I've also done what RT325 mentioned and tweaked the stops as far as I can...  which isn't much.

I remember dads YG1T & it stripped the center drive out of the fiber rotary valve--which we did a few of at work--& i just screwed a reed petal off something yamaha straight over the inlet hole & left the rotary disc off, probably just had the steel center bit in place as needed for spacing crank gear. It worked ok just gutless but for him it was usable until i got a disc.

Thank you, MarkT.
Great info.
