Front end part 3

Ok, more on the front end saga...
The YZF750 forks are in, with new seals and fork oil.
The FZX stock wheel is in, with the special axle adapters I had made (check previous post, Front end part 2), since I'm also using the stock FZX axle.
I got some used Yamaha R6 brake rotors from Ebay (bolt-on onto the FZX wheel)
The YZF750 6pot calipers didn't align with the R6 rotors so I had to make a couple of caliper hangers from Naval quality 10mm thick aluminium.
I made some cardboard templates first, just to get the basic shape and measures.
The pics show just a rough cut of what the hangers will look like.
They will be fine shaped and mirror polished.
In addition, safety lock wire will be applied to all 4 caliper bolts.

Front end part 2

The triple trees are on.
Fresh steering bearings. The stock adjusting nuts have a rubber washer between them. I usually replace this with a solid metal washer and tight the two nuts together as per factory specs.
The top triple tree is from RairoTec, I got this on Ebay real cheap a few years back. It's CNC machined and comes with bolt-on risers to use your stock handlebars or dragbars.
I'm using clip-ons, so the risers are on the shelf for now.

I wanted to do something for a while now, and decided this was the perfect time.
I wanted to be able to use the stock wheels for two purposes:
1- For that "old-school street special" look;
2- They're preparing to have bikes go through a MOT annual inspection (Yes I know, we're lucky bastards so far), so bikes will need factory spec wheels and tires to get approved (probably).
Older design bikes are of course much safer with modern wheels and suspension, but go tell them that.
They discard all responsibility of having to judge if a 17" wheel conversion job is safer or not, so it's easier to say "bikes must have all factory specs", end of story. Bastards...
I needed a quick way to change wheels without to much hassle.
(Here I go again, letting out all my secrets...)
I had two adapters/spacers/sleeves made, that allow me to use the stock FZX wheel and axle (spindle) on the YZF750 upside down forks.
But for this you need BOTH fork legs to have clamping bolts for the wheel axle. This is a must.

Front end

I'm using the complete front end from a '94 Yamaha YZF750 Exup.
I rebuilt the front forks with new seals and good quality 10W fork oil. The springs are Ohlins.
As anyone who've replaced seals on these suspensions knows, it's a b*tch to get the spring spacer and fork cap back on without someone assisting you.
I was really pissed about not being able to do this on my own (again), so I scratched my head, and about two beers later, I designed this in my head and built it using some steel threaded rod and scrap metal bits.
It's ugly as hell but it works, and that's all that matters to get the job done.
The bottom end attaches to one of the brake caliper mounting holes, and the top "grappling hooks" fit in the metal spacer (which has one hole on each side for this purpose).
With one hand holding the spacer/hooks (with a heavy leather glove on, just in case), and the other with a 13mm spanner turning the nuts (which have been welded on to the steel rod), thus pushing the rod and hook/spacer down.
When it reaches the fully compressed position, you can simply pull up the fork dampening rod and attach the fork cap back on. Presto.
Just as a sidenote for all the lads on the FZX Club:
Notice "The BIG Hammer", on the second pic. Always have the big hammer near by, for when things don't go as you liked to. That, and lots of beer...

He's one of the lads from the FZX Club and he makes these awesome custom made radiator covers for the FZX,  in "FZX700", "FZX750" or "FZX1000" layouts.
Check it out.
Thanks Woz, great product!
