Topic: EMGO fork tubes, early style problems?

[mcswny]

Has anyone had a hard time getting the fork pistons on the bottom if EMGO fork tubes (early year models)? It feels like the tube is a fraction of a mm wide or something...

[mcswny]

It seems to be about .14mm too wide and now I have my f'in piston stuck and it won't budge

Emgo makes fork tubes?  How much..
 Tap it off carefully with a wooden or aluminum drift, then polish off some plating.

[mcswny]

Yeah, they were like $120.

But so far wouldn't recommend. F in night mare trying to get the piston on. Any recommended way to polish off some plating?

Hold tube in a vise with padding, then use emery with shoe shining motion..work around it.
 ( unless you have a lathe to use)

Awesome thanks frank. I got one done, will have to finish the other tomorrow

So now that I have access to a computer I was able to do a more comprehensive search and found this post if anyone is interested. It can be hard to do full searches on a phone with greasy hands.

Looks like its a thing and all you have to do is hone the piston or as Frank suggested sand down the tube a little.

They are chrome all the way up and stock length, is that correct?

Yeah.


Still struggling with this second one. Using a brake cylinder hone on the piston and for the life of me can't get it on. Can't figure out if it's just a bad repop fork tube or my fork tube piston is bad.

Maybe just take the piston to a machine shop and have them bore like .15mm out of it?

[mcswny]

Yup, still won't fit. Going to have to find a machine shop to grind down the tube or bore out the piston

[mcswny]

So I've tried using emery paper on the new tubes, emery on the inside of the piston as well as a cylinder hone on the inside of the piston (for a long time).

Should I get the piston bored out like .15mm? And I that's the case does anyone know a machine shop that would do that in the NYC area? Or someone here have access to the tools!

Thanks.
