I don't think it matters. As far as I know, the forks dampers/springs are the same size.

Will deffo fit the curvy forks.

It does matter, too loose in top of pointy damper rod. Doesn't sit right, you can use in pointy but you need to make a bushing.

Chris, if you give me the dimensions of the bush if a pointy buyer want them I will make them on the lathe and chuck them in with the emulators.

Google tells me those codes quoted are racetechs part numbers

3801 = 38mm

4101 = 41mm the ones you appear to have?

If they are racetechs that would be applicable, if not then could be these that are for curvies https://www.debrix.com/ProductDetails.asp?ProductCode=24-0361-VT

Those fit pointies too with spacer, don't see why OD of emu is important as long as it supports spring and seals comp chamber.

Dimension that is different between pointy/curvy is way less that 38/41mm

If the pointy bike needs a smaller insert, I could machine the emulator to fit the smaller damper.

They are the ones from Debrix.
Mine's a curvy.

It needs a bushing to either make emu bigger or damper rod smaller

Pretty sure they're emulators, fegv-s3801's, if you were gonna rip off someone elses design you wouldn't copy it so it looks exactly the same!!
They will be fine in a carby

If these are debrix ones, how come the high price? They are only about £40 new?

Yc, what's yr preference for the pointy bushing, a 'top hat' design so there is a lip that sits on top of the damper rod, or a spacer pressed inside it? I've seen both made in different threads about the debrix emus

Makes no difference on the spacer design as long as its located in damper rod and seals against the top.
They may be £40 but what rate is the compression spring and what size is the low speed bleed, kinda vital in how it works, Harleys= heavy springs, thick oil (up to 50wt in some!!)
Least they look the same!! lol

Doesn't matter, so long as it stays in there. If you have a lip on top remember it will make a small change to preload.

You can change that later if required though.
