​​​​​​ Could you please give some info on the fork extensions. I have ZX6 forks on my project and and I'm interested in how much you were able to  =19.5pxlengthen them. I would like to compensate for the  =19.5pxdifference between a 17" rim vs a 19".

My fork extensions are 27mm long. I have read elsewhere on this forum that you can extend them up to something like 34mm, but because I added the drop at the top triple, I didn’t need to go that long. 

I have some extra extenders if you’d like to purchase a set from me. They are made in stainless steel.

I sure am  interested. How much and how? Do they mount on the bottom of the tube?

How will depend on where you’re located. If you’re in the USA I’d say $100 shipped, but if you’re elsewhere I’ll have to figure out what shipping costs. I can take payment via PayPal or Venmo. 

They mount at the bottom of the cartridge as seen in one of the photos in this thread. It’s an M12 thread, so you probably want to take your forks apart and double check that that’s what yours have.

Sounds good. I'm going to take apart my forks to check. Might be a couple of days before I get to it but I am real interested.

Do your extenders have a drilling through the centre to allow the fluid to return from the "compression" damping adjuster (my ZX9 forks have a banjo style bolt in the bottom)
