Default Ratchet top shift drum question

I have this after market ratchet too shift drum with a neutral type detent that gives a false neutral between 3rd and 4th. Anyone ever seen this or is this a flaw. Oem one to the right and aftermarket to the left. Detent is where the pen is.

Odd, never seen one like that. I have a few aftrmkt ones, I'll see if I can Id them.

Nope, none of mine are twice notched. I can't ID them tho, I only know that they aren't oem. Can't imagine why they'd put an extra detent in it, seems like a phuk-up.

If it's an FX drum, why does it have 2 neutral detents?

If you got it out of the catalogue in the background, I'd be suspicious that it's a mfg. defect.

OR, it's supposed to work in either FL or FX setups, so they put the neutral detent in two places to accomodate either set up.

The extra detent would make it a pain in the dick to ride. If it's something you want to keep, weld/grind the extra detent smooth.

Here's a pic of an oem FX cam from my stash:

Not sure of the manufacturer. It was in a tranny I picked up that had some shifting "issues". Im replacing it with an oem one. Just never seen this before. Thanks for the input guys.

I'v heard of some riders intentionally putting a detent in so that a tankshift lid's false neutrals became real neutrals in the event that they couldn't get to "real" neutral.

I think it would be a huge pain in the ass, personally.

As everyone already mentioned, that drum looks like a fuckup

Here's the FX and FL drums next to each other for reference. Remember that each drum also has it's own corresponding ratchet gear. You cannot use an FL ratchet gear with an FX drum and vice versa...(FX ratchet gears/drums are tough to find, but if you do, the gear is HD 33960-74). Not sure if you're planning on jockey shifting, but I prefer the one up three back orientation of the FX drum.

One of my triumphs had this, used to hit it doing 60 real pain in the ass.

Aye, good info. The first time I saw this was in an old tranny I bought. I couldn't get the neutral light to work right. Took it apart and it had an FX cam and an FL gear. Apparently, the previous owner didn't need a neutral light.
