250-500cc Fork Bleeders - Threads?

[Jhunter]

I was doing a quick search on Rocky Mtn ATV and I see two or three 'push button' fork air bleeders. Most all say 5x0.8 threads. Will these work on the Zokes?

Anyone know?

I bought my Zoke bleeders from Motosports, if I remember correctly they were priced better than most other internet sources.

From memory the Zook forks have the same thread size as WP forks

I just put Motion Pro bleeders on my single chamber 50mm Marzocchi Shiver forks and 4x0.7 is the correct size. It is a tight fit because the hole is so close to the raised hex on the cap, but they do fit.

Yes, they are the same thread

Yes, they are the same thread

Yep I can confirm that too.

OK, I'm going to order the 4x.07 bleeders. I'll report back once installed.

Most suspension tuners that I've talked to recommend to NOT use these. Some say they will actually suck air into the forks. Just a little info, do your research.

I called MotionPro today to figure out what bleeders would work. They didn't have much info on the Zokes. Looks like I'll need to pull the screws out and do some measuring. I'll post again once I have this thing nailed down to a part number...

I bought fork bleeders for my husaberg (48mm white power) and they fit my husky forks perfectly(50mm 'zokes,2010 wr150). Sorry,can't remember the part #.Hope this helps

It will actually depend on which bike (or fork) you have. Marzocchi forks use different bleeders for different models. This is why you are getting different answers.

Correct, Per the guy at MotionPro, the 45mm and the 50mm have different thread sizes or depth ect...

I don't see any mention in this thread mentioning what forks you actually have... 45mm or 50mm, open chamber or closed chamber? As I mentioned before, the Motion Pro 4mm x 0.7 are a direct fit on the 50mm open chamber. I have first hand knowledge of this. Sorry I can't help with other models.

I ordered some MotionPro bleeders from RockyMtnATV. They were 4x.07 and I made sure they fit the WP forks. I think the only issue will be how close the screw hole is to the top of the hex cap. Here's a photo of my top cap.

They will fit no problem

Mission Complete. I bought the 'MotionPro' Micro Bleeders from RockyMountainATV. I have a 2008 WR-250 with the 45mm Zokes (the bleeder screw thread is 4x.07). The RockyMtn part number is #135995001 and MotionPro #11-0080 (Black). If you go by application, I used 2004 Husaberg FC450. The key is 'black' version because it gives you enought room to clear the hex cap. Quick and easy 5 minute job and only $12.99

They look awsome ....! Much easier that pulling the screw. Will they fit my wr250 2004 that has zokes on it but I'm not sure what type. The screw is pretty small.
