Thanks guys!
I wonder how much effect this does, but we will see.

Guy who made exhaust is well known racingbike builder, so I think he knows what he do.
But we will see.

The pipe length from port to collector should be the same on each cylinder.

Not that surprising with how many modern sportbikes have 1-2, 3-4 merge.  Well set up I don't think it'll make a huge difference.  I know merging 1-4, 2-3 helps mid range torque, but merging 1-3, 2-4 done right just acts like a 4 into 1 which is more for top end.  And if it couldn't be made to perform I think factories would have changed it up by now.

Solved few big problems...

Rear shock.
Original GSXR1000 rear shock had a gaschamber and it was way too close to the carb, so I couldn't fit the pods.
Finally solution was to buy a new rear shock

YSS MZ456-305TR-28X. Model is made to fit in Honda CB600 and length of it is 305mm.


Only problem was that this shock had loop-style lower end and I needed fork-style lower end. Also this shock doesn't have interchangeable lower end.


Original fork-style lower end


New shock with loop-style lower end

After some googleing I contacted YSS seller in Finland and they said straight away: "Sure we can change it"  8)

Sended shock to them and after couple days they had switch the whole lower body and center arm. Lenght extended from 305mm to 320mm, which was better than great to me!


Ready to rock!

Now rear shock is attachted. Shock is just right length and has great stiffness, so when you sit down, the rear end doesn't get much lower than in the pics.




Stance is great! I like size of the gap between rear wheel and rear end of the bike


Shipment from the states
4into1 send me a package. It contains new pods, sidestand spring and exhaust gaskets.
Pods look and feels good and finally they have enough room to fit in.  8)






Parts keep coming, but I think I can finally see end of this buying period  :D
Last purchases
- Kawasaki Z750 -06 clutchlever setup
- Shorty-style clutch- and brakelevers
- New front and rear brake fluid reservoirs
- Rubber bits for fastening the tank etc.
- New throttlegrip
- Fuel hoses and filter
- Brake fluid hoses




Z750 clutch setup and new lever


GSXR1000 brake setup and new lever

Still to come:
- New battery
- Wires and electricparts
- Leather wax for the seat
- New mirrors


I also bought Por15-set to coat/seal tank from from the inside.
More of this later.


Next huge thing is to settle wires and start this beauty for the first time in 18 years. Fingers crossed!!
First step for the wiring is done, but lets get back to that later


Original wirings


Months ago I bought bar end mirrors and turn signals.
Just like I thought, I can't install them at the same time because they both use same kind of fastening.

I really want mirrors and turn signals to my bike, although legally you could leave turn signals and one of the mirrors to the garage.

So we came up with this plan:


From the factory this is the set-up. Lens -> threaded rod -> rubber -> washer -> nut.
By tightenin the nut rubber will expand and when you push whole thing inside of your bar, it should stay there.
(same set-up with the mirrors)

This is what we did.
I bought same size threaded rod but longer piece. Drill it through, so it became threaded tube and pull the wires through.
Rod to the lens -> fabricated metal sleeves(?) for the mirror -> mirror in -> nut to tighten mirror to the lens -> Rubber piece (will buy longer one) -> washer -> nut.

Exploided set-up


Finished set-up

This way I got what I wanted.

Clip-ons has to be modified. Have to drill a hole to get wires out.
Wires will come out to the original "box" where all main switches are. Then from there in same route that all the other switches wires goes.


Thinking the future... Wiring, start-up, rear cowl and paint.
Have a good weekend!  ;)
