What? Hip replacements are for old phartes, not youngsters like us.

Yes! The surgeon told me the average life span for a person after hip replacement is 18 months. Statistics

Phil the total opening, where the pads sit, is roughly 22mm. They're single pin Brembos, the bike is a '98 748.
You might get lucky, and will be able to use the original stem in whatever triple you choose. In any event, you'll have some basic necessary dimensions to use.
Different model speedo drives should still allow you to use the original cable/speedo, especially as you'll be staying with Honda bits. Hopefully the differences in tire circumference between your wheel options, won't be too extreme. Playing around with tire sizes, in regards to profile sizes, could be something you could use to compensate for differences in circumference too.

Wow. Mike, I hope you're feeling much better soon - or at least by spring when the riding weather comes!

Mikey, thanks very much for providing that measurement - but I wasn't clear about what I'm looking for. I'm trying to figure out if I have enough clearance to fit the inside portion of the caliper between the rotor and the wheel. Can you measure this:



Sorry about the confusion - I really appreciate the effort.

Overall width is 79mm. That would make the measurement you need 39.5mm.
Does that work for you?

Beautiful, thanks a million!

A friend had a hip replacement when he was about 70. Had the second one done in his early 80s. Couldn't understand why he didn't bounce back as quickly with the second......

Yupper! Looks like they would probably be too tight for the stock rotors, but with the extra clearance I get with the 310mm pie-plates there should be plenty of room.

I just ordered up a set of used calipers - cheaped out a bit and went with the 2-pad ones instead of the pad-per-piston calipers... The comparatively low-rent calipers on that big rotor are going to be overkill anyhow.

Thanks again!

And I also just pulled the trigger on a Bandit 1200 master cylinder. Not sexy like the Brembos, but it has the coffin-type reservoir, integrated mirror perch, and its 5/8" piston should drive those calipers very nicely. If I think it's too much of a mismatch to the Honda clutch perch/lever, I'll swap to a Bandit 600 on that side (the 1200 has a hydraulic clutch but 600 uses a cable).

Calipers, master cyl, and Superbrace all arrived this week. Pro-link front axle is in the mail.

The OEM fork caps off of my Pro-Link forks are also on their way up to Toronto along with some dimensions to go to the fabricator to make up some new fork caps so I can fit cartridge internals like these:

Looks like the 25mm cartridges with external adjustment won't fit into the 39mm forks, so we're doing with 20mm carts.

Caught a break on the weather and I rode the bike into the shop before work this morning. I got a call yesterday from the mechanic there saying that the shop's gonna be closed for 3 weeks but he'll be coming in a bit, so he wants the bike in to work on it when he won't be distracted by other customers. Nice.

My YSS shocks have arrived at Cogent Dynamics (my suspension shop), and they're going on the dyno to check out the valving soon. Hopefully I'll have 'em in hand next week. My sprockets & chain have shipped from Driven, so we should have the back end of the bike sown up by the end of Jan.

I went out and dropped off the stock fork caps at the fabrictor's yesterday - they're going to modify the stockers instead of making new ones from scratch. With all of the work that needs to be done sequentially, and the amount of other projects going on at Cogent and Kreater (the fabricator), and the shipping of stuff back and forth between Toronto and NC I think it's gonna be really tight to get this all wrapped up by spring. FINGERS CROSSED!!!

All it takes is cubic money!

All it takes is cubic money!

It's gonna take some goodwill and luck, too - although money never hurts with either of those things. :)

The order of operations is:

1. Get the 2nd fork cap shipped from NC to Toronto & run it out to the machinist.
2. Machinist modifies both fork caps & calls me.
3. I go settle the bill and pick up the fork caps during business hours.
4. Ship the modded fork caps down to NC.
5. Suspension guy performs internals swap on forks.
6. Suspension guy ships completed forks up to Toronto from NC.
7. Mechanic pulls original front end off the bike.
8. I deliver the original front end, plus the modded 39mm forks, Pro-Link axle, and the brake rotors & calipers to the machinist who fabs up the triples & fits the brakes.
9. I pick up the modded front end from the machinist & deliver it to the mechanic.
10. Mechanic gets everything put back together.
11. I go riding.

What can happen in parallel with that stuff is:
1. Fuse block replacement/relocation.
2. Maybe keyless ignition - haven't decided for sure yet.
3. Probably cyl hone & new rings, new valve guides & seals.


I'm not unconcerned about the money - I know it's gonna be a lot. But my big stress is about the timelines. Lotta moving parts, and a lot of stuff has to happen in order - coordinating across 3 shops in 2 countries.

Phil, you just have to take your time. You'll have all the time in the world to enjoy the work, you don't want to spend any of that time lamenting that, perhaps, you shouldn't have been so rushed. Don't ask how I know
Thank God for Canadian winters...sometimes. If we lived someplace like California, when would we find time for projects/maintenance ?
Go Snow
Keep the updates flowing, it'll all work out for the best, we're certain.
