Okay so I've set aside this weekend for a major overhaul of my 2001 YZ250. I'm doing the fuel/air mixture aswell, should be fun. The lefthand (if you are sitting on the bike) fork's clicker does click, but clicks either way forever, it doesn't stop and makes no difference to the speed of the stroke. Not cool right? And im not sweet with buying a new compression adjuster. So anyway, I thought of a way that not only is completely cost free, awesome way of getting around this issue that also has benefits. Put the showas from my 2005CRF250R (in pieces its destroyed) into my YZ. Not only are the clamps filthy dirty and had to apply copious amounts of lubricant to get the forks out but i've come across two main issues: How do I get the piece that the front axel goes through off the fork? Not just the caliper the actual hunk of metal that screws onto the bottom of the fork, also what is this piece called? And how do I get the cylinders in the caliper to uncompress cos I can't get the brake rotor back in, the pads are all the way together. Yeah mum thought she'd come over and check on my progress and started fiddling with the front brake lever.... Thanks ma.
I'd appreciate the help guys cheers

They are called fork lugs, they are press fit and use a set screw to locate. This is something that I would reccomend for a suspension tech. I believe the diameter of the forks is different and there may be issues with getting the kyb lugs to actually work on the showa legs as far as the rebound damping is concerned. I would reccomend finding some 2005 or newer kyb sss forks they will bolt right in provided you get the triple clamp too. Fixing the old forks is probably the cheapest way to go. I would part out your crf on ebay or something. That should give you some money to work with. Good Luck
Insert a flat blade screwdriver between the brake pads and pry apart.

The bottom of the fork where the axle runs through is called the stanchion, the showa is not interchangable with the kayaba use the front wheel and caliper from the honda.
to spread the caliper insert a larger screw driver between the pads up on the metal above the actual pad and spread them.
However if you are going to use the honda front end, lawd have mercy, just use the whole front brake, as the hose routing is different from the yamahas

Honda parts on a Yamaha?
Sacrilege!! You've just lowered your resale to half 
Oh yeah,what they said above.

I'm pretty sure the showas would've actually fit in the clamps, and I'm confident it took the same axel bolt. But I realised that it will indeed decrease resale value and may in fact lead people to believe the bike has been badly smashed up if its been mixed and matched with these two bikes. So I went back on it. The front brake line that came with my bike rubbed a hole in itself by sliding over the bolts that hold the forks in whenever the forks compressed and the front line from the CRF fits perfectly.
