Australia - Gen2 RCC Stage 1 Kit Build

I forgot to mention I installed the Clutch Slave Cylinder support bracket made by "Exoticycle" from Schnitz Racing.
Also bought the fixed Brocks rear lowering links rather than the adjustable window type. 2-3" lowered in the rear was plenty.

It’s all good Jeff, you can’t make everyone happy. The slave support probably doesn’t hurt and the lowering links are probably good enough.

I have the Brock’s window links and recall others saying they are no good and the Soupys are the ones to get.

I’m waiting to see some onboard riding footage still. :D
 
I didnt think the gen 2 needed a slave support and window links are way better to adjust and setup more.
Unfortunately in this case, yes. Newton's Third Law came into affect.
I could see the slave cylinder was visibly flexing under hydraulic pressure when opposing higher spring pressure therefore reducing clutch effectiveness. Luckily, support brackets are made for the gen 2. I didn't want to wait for it to fatigue and crack.

Now that the support bracket is installed, the clutch lever no longer feels spongy and the clutch grabs closer to the bar. It's also a more positive and reliable feel. There's more bounce back in the lever.

Window links are great; they're also nearly $200. Cost per inch varies a lot it seems. I only need a 2" drop to match the Trac Dynamics 2" drop front fork inserts, but it seems I've been ghosted on that order since October last year. He is impossible to get in contact with. Maybe I'll try Morse Code next time because telephones and amicable emails don't provoke any response.
My bank is investigating and hopefully I get a chargeback to my account, or possibly insurance claim, but I don't like my chances. I may just write it off as a learning experience when purchasing stuff from abroad.
 
Update:

5000 km later of endless Hayabusa fun and many, many boosts, I forgot to factor in during the build that by installing higher tension valve springs which naturally puts more tension on the cam lobes and in turn requires more chain pressure to rotate the cam shafts, definitely needs a heavy duty cam chain and gears! I thought 300HP would be ok, but nope! I will measure the stretch comparison to a new chain and post back here.

Pulling the engine out back very out very soon to replace it all and change out a few other things and install an RCC Throttle Body Clamp and ditch those rubber boots. I'll take some pics.

I tell people I'm actually excited to break open the engine again and they pull a face at me. Well, if I paid someone to do this all for me, I wouldn't learn anything right?

Taking a nice long break from work soon so I'm keen to work on this beast again! @JeffSyh you are right, I'll never be finished with this beautiful machine called the Hayabusa. I'm addicted.
 
The cam chain hadn't stretched, but the drive chain did :p
Over 10,000km has passed on this build now and frequent oil changes and air filter cleans.
Valve clearances are fine.
Running tight and sounds good. Always get good oil and change it frequently.
Turbo itself is running great.
The blow off valve was worth getting.
Swing arm extension wasn't needed.
She drinks fuel like a drunk sailor.
With the bike's weight reduction and 313 hp, it's perfect for picking up the milk and bread as a daily.
This bike was a build intended for reliability, not economy, and it's proven it in mileage and maintenance. RCC gets my tick of approval :D
Never regretted a second of it.
 
First of all, thank you for this post and these feedbacks over time, and through your post you answer a lot of questions that I asked myself.

A few quick questions though:

-What type of injector do you use?
-You don't have an intake temperature problem with this configuration? (no cooling) in road use?

There is still room in front of the radiator to put an exchanger, do you think? Even small?

You would have photos of your finished motorcycle from various angles ?

Thank you in advance for your answers, I will probably need to contact you for my editing (see my post)
 
Apologies for the late response.

Injectors can be OEM standard for Stage 1. You'll just run out of fuel delivery above 350 hp give or take. Other people here may correct that figure.
But at 315 hp, stock fuel injectors and air at 12psi is sufficient.

No temperature problems whatsoever throughout all seasons of the year.

There is room for a small heat exchanger on the right hand side of the bike, or other intercooler devices. So far I haven't needed a heat exchanger.

I insulated the air intake pipe with heat wrap so to minimise heat conduction into the pipe from the engine.

I can take more photos.
