Brembo Porn

Back in September, my wife gave me a Brembo 19x18 forged master cylinder for my birthday. Without having installed it on the bike or pumped brake fluid through it I can't say how it performs, but damn its a sweet looking piece of kit.

That's all folks (for 2012)

Life has thrown quite a bit of stuff my way over the last few months and with what looks like an fall chill setting in, I decided to pack it in early this year. The down time has given me time to do some stuff on the bike and generally shift focus from maintaining a ridable machine to adding on major components for next year .

First thing I did was try to sort out the F-Hot carbon fiber intake tubes. Like I mentioned before, the F-Hot tubes really don't work too well with standard CV carbs and standard airbox.

Definately going to leak air here ... shop towels wedged behind the tubes for visibility




Tubes don't quite make contact with the airbox resulting in leaks all over the place


I'm not quite ready to reinstall my FCRs yet so in the mean time something must be done to seal up the massive gaps between the tubes and the airbox. I went down the home depot and got myself a roll of weather stripping foam; the thickest one I could find.

This stuff is supposed to be good enough to seal my windows so an airbox should be a cake walk (never understood that expression)


The weather stripping material basically replaced the factory rubber seals around the airbox intake. One strip on the inside and one strip on the outside creates a very tight seal. Looks decent too.

One strip taped to the inside of the opening ...

... and another one around the outside of the opening ...

... creats a tight and handsome looking seal ...

Much better


Another 'leak' that I discovered with the F-Hot tubes was in the front where the tubes meet the mesh grille. The standard grille and rubber fitting is a little more 'round' on the outside where the F-Hot tubes are a little 'flat'... if that makes any sense.

Holy fitting issues Batman!

A gap large enough to fit an average sized school bus


To remedy this, I basically taped the ducts to the rubber pieces that join the intake tubes to the front fairing. Not the most elegant solution but it doesn't look half bad and solves the problem. I didn't take a direct photo of it but you can see the fix in some pictures below.

So while that pretty much wraps up the intake tube installation, the biggest project (and one that is yet to be completed) is the front end upgrade. I've been collecting parts for this all year long (wheels, forks, brake master cylinder etc. etc.) and just last week, I finally got the critical component I had been waiting for! Dan's custom triple clamps!

Really no need for captions... the pictures speak for how gorgeous these are








Dan makes custom triple clamps specifically for the ZX7. He has one version that uses standard forks and another that will adapt a ZX10 front end to a ZX7. Luckily for me, I just happen to have a set of ZX10 Ohlins forks and OZ rims! Yay!

The pictures speak for themselves, but these triples are absolutely gorgeous! The only visible fault is some tool chatter marks in the middle of the bottom triple and a tiny bit of chatter at the bottom of the top triple. This certainly isn't representative of Dan's work since he cut these up for me in a hurry while he was moving his shop. When he gets settled down we'll figure out what to do about these chatter marks.

Chatter marks; only blemish on this otherwise brilliant piece.


So fitting the front end is pretty simple. First the bike had to be stripped down of course

Now at this point the old triples had to come out which is a bit of a problem because without wheels or forks, the only thing supporting the front end is the front stand.... which is plugged into the old triples.

I resorted to using two hydraulic jacks to hold the bike up while the front stand was removed. If I had bothere to remove the exhaust I probably could have gotten away with using just one.

Jacking up the bike while the front stand is removed is by far the most nervous part of the install.


Another difficulty with this install is removing the old bottom bearing from the steering stem. Luckily I had an All Balls steering bearing kit lying around that was advertised as a direct replacement for the ZX7RR N1.

The All Balls bearing is on the left. The OEM is on the right

While the bearings may have been close in dimension, the races definately were not!


Since I didn't plan on riding my bike until next spring, I figured using the All Balls bearings temporarily would be okay. Dunno when I'll be able to press the OEM ones out... hopefully soon.

The All Balls dust seal is considerably smaller than OEM... not great. I'll have to order an OEM one

New bearing hammered into place


With my temporary bearing situation figured out, I slapped my triples on and slid my forks in.

Looks good!

mmmmm... looking more business-like


Although the triples look great, there are a few areas of concern. The bottom of steering head is spaced very close to the bottom triple; there's a gap of about 0.15mm. Maybe this is due to the stupid All Balls bearings. There's also a chance that a small clearance isn't even an issue. Hard to tell without riding the bike thou.

With the triples fully installed, there is very little clearance between the bottom of the head stock and the triple ... won't know if this is an issue until I ride the bike


Another issue I noticed was that the steering stem doesn't become flush with the top triple like I thought it would. Once again, maybe not an issue. For all I know it's not supposed to be flush.

The steering stem sits a little deeper into the top triple that I'd like to see...


The last issue was that the ignition barrel mount couldn't be monted due to contact with the dust steering column dust cover. From what I understand, the ZX7RR N has a lager steering column than the ZX7R P so the vast majority of ZX7 owners shouldn't have this problem.

Ignition barrel mount doesn't quite clear the black dust cover


Before I mounted everything I did a quick weight comparison between the OEM stuff I took off and the new stuff I put on:

OEM forks + triples = 25lbs
OEM front wheel + rotors + tire + spacers = 30lbs
----------
Total = 55lbs


Ohlins forks + custom triples = 22lbs
OZ wheels + rotors + tire + spacers = 25lbs
----------
Total = 47lbs


So far the front end swap has saved 8 pounds, at least 5 of which is unsprung weight from the wheels! Nice!

So that's it for now. Clipons and calipers are next! Here are some more shots of the forks and junk.

Hectic Days

Been keeping busy. Lots of stuff happened recently.

Friday
George (R1 Buddy) and I went up to Grand Bend race track to check out the Rider 5 racing school. The track is about 2 hours west of Toronto so it was quite a drive up there but we saw some real fast riding and met some great guys and gals.

A very scenic drive to Grand Bend

Track bikes look so much better than street bikes ...

Hmmm.... yes I approve of this one




On the way home, we stopped by at Zdeno Cycle for the first time and were struck with awe by the amount of stuff EVERYWHERE. Entire ceilings covered with fairings and shelves upon shelves of carburetors. It was quite the orgy of old odds and ends.

Walls of fairings

Stacks of forks

Halls of wheels


At the end of the day, we stopped at Tom's house. Tom is an ex-Suzuki factory mechanic with a massive collection of rare bikes; a superbike spec OW-01, a superbike spec OW-02, a Buell XBRR, a TZ350 (harris frame, all original), and a Vivaldi superbike spec ZX10. I'm kicking myself for not taking more pics of Tom's incredible collection but you can sorta see the Harris modded ZX10 swingarm in the pic with the OW-02 fuel injectors.

OW-02 throttle bodies. Throttle bodies that are worth more than your car


Saturday
George and I went across to Buffalo where I picked up my Brembo forged master cylinder from Hard Racing... which was shipped over a week late. Weeks earlier my wife bought me this as a birthday gift. Thanks baby!

Another step closer to finishing up my race rep front end.

Brembo! Damn, my pants!


Sunday
George and I finally got around to installing the Harris swingarm onto his minty fresh 1998 YZF-R1... and she is a thing of beauty!

Almost there ...

... and we're done!

Happiness is a garage full of bikes :)



Unfortunately we hit a few snags. First, it seems the OEM rear rotor is too big for the AP racing caliper. Furthermore, there appears to be quite a bit of play in the wheel on the rear axle. We suspect that this is due to the fact that the caliper hanger (which doubles as a wheel spacer) is designed for the 2000 R1, which probably has a smaller rotor and wider hub compared to the 98 R1.

Hmm... either the bracket is too short or the rotor is too large

Monday
Showed up at the office and saw a big box at my desk!

Light weight + big box can only mean one thing ...

... carbon fiber!



F****** Hot is right!


I got these carbon fiber ram air scoops from former BSB Racer Dave Redgate. I'm not sure what his affiliation with F-Hot is but his ebay account sees these ram air scoops moving regularly for decent prices. Unlike many other scoops, these ones are designed to work with the stock airbox OR the carbon fiber race airbox. The flexibility is nice because the race box is both rare when your looking for one and expensive when you find it.

The grills were a tad difficult to fit... I imagine they were originall designed for racing applications and therefore not meant to be fitted with a grille


I noticed the seal between the ram air tubes and airbox wasn't the greatest. I suspect that although these tubes are designed to be compatible with the stock airbox, they are designed to work with FCRs as opposed to CVKs. I don't have any weather stripping material on hand but I suspect that it can be used to improve the seal... or I'll just reinstall my FCRs when I get them sorted out.

Overall, the air tubes are very high quality. The carbon fiber is nicely formed and there is very little distortion of the weave, especially for such a complex shape. The fit around the front grilles could be better but I suspect it wouldn't be an issue on race fairings. All in all I'm pretty happy with these tubes and they make the bike look great. Will take some better pics when the sun is out.
